Disc Nr

Thank's

This is the problem:

It would help to see your UV layout, but it looks like an issue of some UV pieces being scaled smaller then the others, or flipped/mirrored? Around the neck it looks like there is insufficient padding and the edge is bleeding with the background.

Hi

I attach the reduced dimension of normal map, i think you are right but it are unwrapped in this dimension, i don't have change any scale

normal map:



Thank's a lot for help

sorry i have no real idear.. it looks like the part of the legs and the upper arms have wrong normals or something.. the normalmap looks not that bad

is your model fully smoothed and have you set "reset xForm" and..

Hi rollin

Thank's for your reply

If i see it without any map it look uniform, if i put diffuse color total pink without normal map, it look uniform, when i put normal map it is break, in diffuse i have fix some dark brown line a the border but normal map are discontinued to, if i don't resolve it i think must re unwrap all model

Thank's

I can't get the full-size image in the first post to load. Can you re-post it?

export the model as obj and reimport it.. ?!

what map do you use to display the normalmap in max?

Eric Chadwick

You need to use the right kind of shader to avoid seeing seams, one that uses the tangent/bitangent data stored in the mesh. Load any of these .FX files using the DirectX Shader material:

J.I.Styles' skin shader.

Ben Cloward's shaders.

Make sure to setup the lights in the shader, and often you need to specify a diffuse bitmap (you can't leave that slot blank).

Hi Rollin

I display it in bump -> normal map, and load normal map generated by z-brush before export normal map i flip it, i have see now this problem are the same in zbrush before exporting, i remapped it today and re try if it work fine.

I use standard direct x shader for use it in 3dsmx becouse i don't know other way, the last image for the contest must is render or only realtime grab? i ask it becouse i had read are allowed Real Time shader like HL2, UT3 e Crysis, can you explaine me?

Thank's a lot

The default shaders in Max incorrectly display normalmap lighting in the viewport.

• Standard material, bitmap loaded in the Bump channel via Normal Bump, using the checkbox DX Display of Standard Material.
• Standard material, Enable Plugin Material = Metal Bump9.

If you want to fix the seams, you should use a third-party shader instead. I don't know what the contest requires though.

Oh my good

Now all perfect, but when i make render appear this error message

MSG 0.0 error: Material "19 - Default ( DirectX Shader )" not supported by the translator. Will render black.

Any tips

Eric Chadwick

I sent Joel an email about his site, maybe he'll fix the link.

What do you mean "when I make render"? The DirectX Shader material is for the viewport only, not for the scanline renderer (nor VRay nor mental ray).

Disc Nr

OK Eric

In this way fo rthe contest is correct make grab form the viewport or must make scanline render?

If must make viewport grab im now ok else i must resolve, for see in the sam mode viewport and definitive render, sorry for nob request but it is my first war, i don't have experience in this contest :P

Thank's a lot for your great help

Bye

A viewport screengrab would be fine as long as it shows your model how you want it.

Disc Nr

Thank's for reply MoP

In this way you confirm are sufficient viewport screen grab for the definitive presentation in the Dominace War III contest?

Can i edit it in photoshop, or only realtime view?

Thank's

Read the rules.

Looks like only a realtime view, using standard shaders. So the shaders I gave links for are not allowed.

But... you could take a screenshot from one of the listed games. Xnormal is also a good way to go, I know it handles seams properly.
