Hi everyone, I am making a movie with poser 12. Everything goes well, but I decided to try Poser 13. At first, no problem, but something went wrong on my last scene. (see images). At first, I thought that was bcause of the distance (a lttle far away of X and Z =0) But that dont make sense, because the character was at the same position of the previous scene and everything was ok. I try almost everything ; free the ram, reload, save PZ 3 again, reload the file in poser 12 and save again and try...again with poser 13. Nothing works. So I am back with poser 12. Someone, has an idea of what went wrong ?

It looks like it's just on the character's skin, so probably a shader problem. Can you post a picture of the material for the character, for the arm, face, or neck?

Sure.Thanks. It work well with Poser 12, but may be it's too simple for P13.

The problem with the old skin shaders is that the creators continue using old hacks and outdated channel connections that are no longer appropriate for Superfly or Firefly  rendering.  Aside from unticking the Reflection_Lite_mult box, I would try disconnecting the Gradient_Bump channel or reducing its value to 1 or lower.

The other recommendations I suggest are disconnecting the color texture from the Specular_Color connector (should use a grayscale map for that) and reducing both the Diffuse_Value and Specular_Value values (0.85 and 0.5, respectively).

Keep in mind, some of those material shaders are very old and are no longer valid in the current Poser iteration.  There have been changes between P12 and P13 to correct problems that were always there since the beginning.

I've had that issue with the bump being too high. drop it way down. My default is usually 0.3, but experiment.

Thanks Guys! The poser community is really great ! I'll check in my library to find a newer M4 maps and try it in Poser 13 again.

You could also use a PhysicalSurface base node instead of PoserSurface, plug the image map in to that. If the bump map is actually a bump map, plug it into the bump node and give it a reasonable value like 0.01-0.08, set the roughness somewhere around 0.5. Sometimes the maps are just fine but the node settings were the weird part, and PhysicalSurface does a better job especially if you are using Superfly.

Thanks you a million time ! It's now ok!

Here,s the result :-)
