Multiple Shader On Object Problem

[user_deleted]

Hello. I have a problem many times this seems to be a common type of corruption in maya. I apply many shaders to diffrent faces on an object. When I select the object I see them all but when I deselect it some disapear. And it wont render some shaders. It seems to happen when I apply the shader to one area and then apply a shader over it or over some faces where that shader was. Maya shows the previus shader on certain faces unless I select it. I know I can export the object as obj and it usualy fixes any problems I have with obects. But If I have carfully selected it this can be a pain to reselect everything. Has anyone else experianced this or know a way to fix it?

the way they are laid out here suggest they should not discern form the face next to them... becase they are planar and share upright normals, it sa actually a what poly is trick here.

seme applies to suitably sampled splinic zigzag, it may well be intentional. Because i do things like that intetionally because this makes for a appearrance of rounded corners where theres none.

Thanks for answering my question but Im not sure if I understand you correctly. I beveled the corners, yes to give the rounded apearence as you are supposed to do with hard surface modeling. I plan on later making the area inside a lcd panal and use 2d texturing. but that is beside the point. Its not a normal problem I did "set to face" and all the normal tricks. I have moved on, exported this oject as obj and reselected all the faces and reaplied the textures by now, but it is a problem the contiues to plauge me. Others at my work have experianced this problem as well.

Not necceserily.

if you have 2 faces thet are on the same plane, then theres no difference between those faces once you deselect thus they would look like one plane wich is what they should be.

The reason you do thet is for the normals to generate a auto normal that is tactually pointing along th plane.

HOwever if you say bevel then yes i know what the reason is, its because the beveled region does not have a uv cordinate and sometimes this leads maya to draw it as transparent.

However this might also be a bug in the gfx drivers state machine. Ive seen it only once on a ati card.
