Character WIP - C&C welcome

Hi everyone, this is my personal challenge for this month, a character! Based on this concept


At the moment I'm on the sculpting phase(more focused on the anatomy), and when I'm done, I retopologize and detail + texture.

I would like to hear from you all if, the anatomy needs to be changed, if not, I go to the retopologies.

C&C are most welcome!

Thank you

Guys, i need some help!



I just retoplogized the body and head and UVed it. Experimented a displacement map 2048*2048!

Went to maya and rendered it in mental ray. Is that a displacement problem? Subdivision aproximation node? Uv problems? What is it? =X

Thank you! Help me =)

High res image! You can zoom and see the displacement "malfunction"

Yes, just tested and its the map resolution i think! Tried 4k maps and the i dont see those artifacts anymore!

I think its the resolution. I tried 8k maps, and i still see those articats on the eyes and mouth =s

What's the bit-depth of the displacement map? It should be at least 16-bit. 32-bit is even better but sometimes not necessary especially as the file size can get large.

I tried with 16 and 32 bit! Tried 4k and even 8k. And in eye area the displacement wasn't perfect, still had those artifacts, i don't know but i think that it is from the Uvs, what do you think?

It could very well be the UVs. Sometimes in those areas the uv space can be so small that even 8 maps are not big enough to contain the sculpted detail.
Can you show us your UV layout?

Thx for the help pap87 =) I have 3 screenshots of the Uvs for you to analyze








you can zoom the last one in this link:

Thanks

Hmm, I doubt it's the UVs then. They look good to me. Seeing how the strangeness is happening everywhere I'd say the fault might be in the displacement map. Do you see any strangeness, pixellation or artifacts in the map? Perhaps it didn't get written out properly or wasn't made with the right setting? Can't say I've run across this before.

Did the bit-depth of the displacements make any difference at all on the renders? Or the resolution of the maps for that matter?

And in what program are you making the displacements? In mudbox for example, there is a little checkbox that says "Smooth Source Models", which you might need to check if you get faceting from your source mesh.

Well, it's the displacement map itself that is causing this problems. I tried 16bit and 32 bit displacement. Tried 2k 4k and 8k maps, and they all had this problem on the render.



There's a white artifact on the eye, that is causing a great deformation on the mesh, i cleaned it out and i blurred the eye area and the mouth area, and still had the problems!

lawafilm, there is an option that i checked "SmoothUV" and "Adaptive".

I tried displacement maps with other models and this is not the first time that happens.

Due to this situation I decided to make it a game model, based on the concept!

Thank you guys!

Hello again!

Based on the concept, I'm finishing the model and going to make it a game model!



You guys think that i should retopologize the legs and the torso separately?

Trousers + legs bandage + feet armor + feet ? 1 Mesh?

Torso + arm bandage ? 1 Mesh?

Skirt + Belt + Medallions ? 1 Mesh?

Should everything in the model except the sword, be in the same UV space?


Note:

This is my first game model. I have never done any before. Any help it is very appreciated!

Thank you!
