Hi,
is backface rendering possible with emitter material ?

What are you trying to do exactly?

[Frank1000]

i'm trying to get the backface of a mesh shaded as well.

This might be part of a bigger issue (bug?). I am trying to render a piece of paper with different graphics on each side (it is a simple single polygon). I have applied different materials to the main and backface parameters but it still shows the same material on both. Is the backface feature working in Softimage (2014)?

[Frank1000]

yea just from the SI 2014 Texture Decal it's rendering both sides. I was using the same texture though.

Right now the engine only supports adding backface materials on meshes, so at the moment backface materials are supported via a parameter in the Maxwell Mesh Attributes property. Let us know if there are any other workflows in XSI to add a backface material to a mesh that you would like us to support.

If you set the backface material in the mesh attributes and it still doesn't appear, can you send me a scene that I can use to reproduce this bug ?

Hi Raduc,
thx for reply. I had used it but it gives me black backfaces yet.

Sent you .scn tp pm

I forwarded this question to the engine guys and unfortunately this is a limitation, backface materials can't be emitters.

[Frank1000]

ok thx for info.

Maybe duplicate the geometry, apply an emitter material to it, and hide it to camera?

[Frank1000]

yea that's one way for lighting effect. in my case i just gave it dimension.
