Forge your warrior in the ultimate 3D sculpting and painting challenge.  Stretch your imagination and show off your creativity.  Warriors can be fantastic, futuristic, historical, ethnic or anything else you can dream up.  Is your warrior organic or mechanical, male, female or creature, low or high tech, cute or fierce, cartoony or hyper realistic?  The options are endless, the choice is yours, let the battle begin.  Artists of all skill levels from around the world are invited to join in the fun.  This is a great opportunity to have your work reviewed by some of the most talented artists & judges in the world, and you never know who might be watching your entry or where it might take you!

war · ri · or –noun
1. engaged or experienced in warfare; soldier.
2. shows or has shown great vigor, courage, or aggressiveness.

After you have a concept for the warrior you would like to create, you will need to bring your creation into 3D.  Use Mudbox to sculpt and detail your warrior’s mesh, and use Mudbox’s painting features to texture your character.

This is a sculpting and painting challenge with a focus on character, so an ideal submission would be posed, painted and rendered, ready to spring into battle.  Please do not submit flat shaded models in t-poses.

To get started, create a WIP thread in the Warriors forum with your name and entry name ie. <my name> - <warrior entry name>.  Use this thread to post your progress and WIP shots with the community.  When you have finished your entry, post it to the finals thread in the Warriors forum with your final images and a link to your WIP thread.  Click Here to go to the Warriors Forum.

Don’t have Mudbox?  You can download a special FREE 3 month trial just for this event. Click here to download the trial.  For a list of serial numbers to activate your special 3 month trial version CLICK HERE.

3 months to see who will be the last artist standing. 
October 15 2010 - January 15 2011.
Final entries are due by January 15, 2011 12pm pst.

Model sheet - front, back, side and 3/4 view of your final modeled and painted warrior.
Beauty render - show off your model with some nice lighting and show off the best angles of your warrior.
Above the call of duty - (not required) a 3D turntable of your final model, and possibly a breakdown or making of.


1) You must use Mudbox for all 3D sculpting & painting of your warrior. 
This challenge is sponsored by Mudbox and we want you to discover the powerful tools it has to offer, so you are required to use Mudbox for your sculpting and painting tools. Other 3D sculpting software is not allowed for this challenge. You may render in any software you wish.  You may use other programs like Maya and 3ds Max to work on the base mesh, but all 3D sculpting and painting should be completed in Mudbox.  If you don’t own Mudbox, you can still participate by downloading the 3 month trial.  Additional painting and touch ups in Photoshop are acceptable.

2)  You must keep a wip (work in progress) thread documenting your journey to the final image.  Don’t post your first and last image only, we want to see the steps in between. Failure to post wips could lead to disqualification.

3)  You may not re-use existing work.  You may start with a generic human base mesh, but it should be simple and not overly detailed so you don’t have an unfair advantage.  If you start with a finished model and just add a few details on to it your entry will most likely be disqualified.  You must disclose where your base mesh came from if you use one and show a screen shot of it before you begin modifying it.

4) You may have multiple characters in your submission, for example, a warrior on a mount.

5)  You may submit as many entries as you would like, however we suggest you focus on one idea and develop it as much as possible, focusing on quality over quantity.

6) You may not use an existing character from any source (film, comic, movie, game, etc.).  All warriors must be original designs to qualify for prizes. Historical and mythologically based characters are an exception as long as there is no existing copyright on the character.

Q&A (Updated Oct. 17, 2010)

Q: Where do you post the WIP for the Mudbox Warrior Challenge. Im new to CGHUB, so please bare with me.

A: Just go to the Warriors forum or click on the link below, then click "New Thread" and name it like: <username> - <entry name> ie. mstone20 - myWarriors name

After you've made your first post, you might want to subscribe to the thread so you get updates, and bookmark it, so you can quickly access it when you want to update your progress (just click "Post Reply" to add a new post to your thread.)

Good luck!

Q: Could we 2D artists design a warrior that a 3D artist could use?  You know, either collaborate or just post up for anyone to use?

A: Yes, you may team up with a 2D artist to do the concept if you wish, that's fine, as long as you have permission to use the concept and it's not copyrighted by anyone else. Please DO NOT use someone else's concept without their permission. If you win the challenge, we can only deliver prizes to the 3D artist, so it's up to you to divide them up amongst yourselves (we can't be responsible for 2D artists not getting prizes if the 3D artist wins.)

Q: I thought it was a 3 month trial all I got was 30 days Is that what the serial # is for.

There is an option after you install which gives you two options before you begin to use the program, a 30 day trial or verify the serial/registration. Make sure you pick the second option, not the 30 day trial. That should activate the 3 month trial. Please let us know if you have any problems!

Q: Can I use default Human Body in mudbox as my base mesh because I'm sorta just getting used to working in 3D?

A: Yes, the default human body mesh that ships with Mudbox 2011 is ok for everyone to use as a starting base mesh, along with their other base starting meshes. Thanks for asking!

Q: I really want to join this challenge but i have no idea about 3d ?!?!?

A: One of the points of this challenge is to give all artists an opportunity to try 3D sculpting, you could always watch a few of the tutorials posted here and then check it out? We would love to see what you could come up with  If the 2D guys would just give it a few hours to play around with, you might be surprsied how accessible 3D is, and it's becoming more and more a part of the 2D workflow as another tool in the artists belt.

Q: Any requirements for polycount or textures size?

A: There are no restrictions on polycounts or textures, so go for it!

Q: Are we allowed to use another program like Maya or 3ds Max to create our base mesh, or does it have to be mudbox right from the start of modeling?

A: You may create your base mesh in any package you wish. Please post a screenshot of your base mesh in your WIP thread and explain how you created it. The sculpting and painting should be completed in Mudbox.

Q: Hope it's ok if i forward people on other forums?

A: Feel free to spread the word about the challenge, just make sure to get permission before posting elsewhere (not from us, but from the places you will be posting so it's not perceived as spam).

Q: GIMP, Blender or other software ok?

A: Yes, for example if you don't own a license of Maya, 3ds Max, XSI, etc, you could use free open source software like Blender to create your base mesh and Gimp for your final touch ups and composting, and you wouldn't have to own any 3D software to participate in this challenge. Mudbox should be used for the sculpting and painting aspects.

Q: I have one question regarding the race of the characters, for example it can be of any fantasy race right? for example orcs, trolls, kobolds, gnomes, dwarves right?

A: Yes, fantasy races should be ok, just don't create a recognizable Dwarf, or Orc (say from Lord of the Rings, or Warcraft). Your character should be unique and original.

Q: Can I have multiple entries (judged separately?) cause I have loads of ideas.

A: Yes.  Take a moment to consider time restrictions and focus on quality over quantity.

Q: Can I use other software for things that Mudbox doesn't offer yet such as retopology and UV unwrap?

A: Yes, use Mudbox for the sculpting and painting processes, that is the focus of this challenge.

Q: A warrior is not always the winner. If I portrait a defeated warrior, will it be ok?

A: Yes, that's an interesting take on it, we encourage you to think outside the box to come up with an original warrior concept.

Q: Any restrictions regarding nudity or gore?

A: No restrictions, but keep in mind winners will probably be used for marketing purposes, so if it's too extreme you might be hurting your chances of mass exposure due to adult content. That said you could always submit 2 versions if you like, a more conservative one and your version.

Q: Any restrictions regarding a diorama? Let's say I want to portrait a battle with 2 to many fighters. Is it ok? Or should I model A warrior and that single warrior only?

A: You could do a diorama and multiple figures, but when it comes to the 3D print, you might have to select just one to be printed.

Q: There is no specification for what the figure should be, so it could be a bust as well as a full figure it seems?

A: Yes, you could do a bust, but it should be full painted and be "posed" for your final (ie. try to show some character).

Q: As the winner will have it's model printed, shouldn't the rules include specifications for that? What are the limitations for textures in models that are meant to be printed, for example? Is there a limit? Will the the textures be printed at all? What format should I use? What's the minimum thickness for objects? and so on and so forth. Printing has way too many rules that most people are not used to.

A: Offload Studios will be posting some guidelines for the 3D printing process shortly, please keep an eye out for those. Those are all good questions for them! Visit the Offload Studios Warriors Landing Page for more info

Q: Can I use Maya (or other program) for creating object kind of lowpoly mesh like armor, swords, guns and such? Are these objects counted as basemesh?

A: Yes, you can use any program you wish to create the base mesh. Make sure you post a shot of your base mesh before you begin sculpting. (If you are a student or a newbie to 3D and don't have any 3D software, check out Blender, a free 3D app where you could model your base mesh.)

3D sculpting and painting should be completed in Mudbox.

There are no software restrictions on base mesh creation, UV mapping, re-topologizing, or creating the final beauty shot render comp (ie. 2d software like photoshop, shake, etc.).

Q: If my model has hair , fire or smoke can I create it with other software?

A: Yes, you can use other software for your final renderings and beauty shots to add effects, like smoke, fire, fur and hair. Your final touches (hair, etc.) could be hyper real, or you could try to model a stylized version of these effects which could even translate into the 3d print possibly, it's up to you!

Q: Can I show my base model in my native software?

A: You can create your base mesh in any package you would like. The emphasis here should be on the high resolution sculpting and texture painting that happens beyond that point of fleshing out your base mesh. You need to show a screen shot of your base mesh at the beginning in Mudbox, and from there you should be working with Mudbox for sculpting and painting the final high res mesh.

Q: This challenge sounds very similar to Dominance War?

Maybe, but if you look at most DW entries, they tend to gear towards the darker side, hyper detailed and photo real, largely influenced by death, demons, etc. (not all, but many - this is nothing against DW, it's just what usually gets generated for that challenge). Feel free to go down that path if you'd like, there are no content restrictions.

For the "Warriors" challenge, we are hoping to see a wide range of warriors in different styles, cute warriors, historical warriors (think of the possibilities...samurai's, ninjas, cowboys, indians, ww2 soldiers, just to name a few), sci-fi and fantasy warriors, your imagination is the limit. You could pick a specific person from history, your culture, religion, country, mythology, and develop that, or you could create something completely original.

Q: Can we render the beauty image outside mudbox?

A: Yes, you may render your final images in any renderer you wish, or you could submit a high res screen shot from within Mudbox if that is not an option for you. Judges will be focusing more on the quality of your sculpting and painting rather than your final image quality(remember it's a sculpting and painting challenge, not a rendering and compositing challenge) so if rendering and lighting are not your strong points don't worry too much.

Q: Can I use subsurface scattering and compositing to improve the final render in compositing/post?.

A: You can use any rendering techniques you would like for your final render. You may composite your layers in photoshop or using a compositor (like nuke or shake), that is ok as well. The sculpting and painting should be completed in Mudbox. You can touch up your textures in Photoshop or other 2D painting app, but the majority should be done in Mudbox.

Q: Where is the Australian 3 month trial serial?? it has a space for it in the text file but there's nothing there?

A: It's in the txt file, the first in the list: Australia - 356-99139039

If you guys have any difficulties with serials please let us know and we'll make sure we get an update for you.

Q: I am from Peru I can participate?

A: Yes, please try using the Americas serial: 356-85672271

Q: I just have an idea for a Jedi Hunter that I'd like to go with, is that ok?

A: That's the issue, "Jedi" and Star Wars universe items like light sabers, blasters, etc. are copyrighted material, so it would be a safer bet to push your character enough so that it isn't a recognizable part of the Star Wars universe. Hopefully that makes sense, if you have other questions regarding copyrights or if an idea is ok please let us know in this thread. Good luck!

Q: Are 2d model sheets or 3d model sheets required?

A: 2D model sheets are not required, the 3d model sheets will show off your sculpt from different angles.

Q: Should i give it a try? I'm pretty positive I won't stand a chance but hell, guess i'll do it for fun.

A: Go for it!  It's a great opportuinty to learn new things and get support from the participating artists.

Q: I'm in. But i have a question. Is ok if i want to export/import mesh from mudbox to any 3d software to render and compositing for the final image?

A: Yes, you may import/export for the final rendering and compsiting, as well as while building and working on your base mesh (example maya ->  mudbox -> maya or 3ds Max -> mudbox -> maya)

As long as you use Mudbox for your 3d sculpting and painting you are good. We don't expect you to create your base mesh in Mudbox, or do your final renderings in Mudbox.

Q: Does posing count as "sculpting" or can it be done in a different program?

A: You can pose your character (say with a rig, or deformers) in another program, that is fine. Mudbox has some nice posing capabilitles which you shoud investigate, but as long as you do your sculpting and painting in Mudbox you could do your final posing elsewhere for the finished renders.

Q:  I'm planning on completing my character in another program, then I'll just load it into Mudbox for a few screenshots, nobody will know the difference.

A:  Come on guys, please be professional and don't try to game the system.  If there is any question that you didn't use Mudbox for the 3D sculpting and painting you run the risk of being disqualified.  This is a Mudbox challenge, please respect that.
