Mental ray and Render to texture problem.

[Andrew75]

Hi , I'm having trouble with rendering to texture using Mental ray,

in the picture above,,,
the green texture on the left opened in MS paint is what renders out and saves from 3D studio.
ive tryed a few formats like TGA BMP ect,,

While the right picture is rendering within 3D studio is exactly what i want.
i can save it from the rendered picture, but it doesn't have any padding.

also I'm using a Blend material. with noise as the mask.
it just saves first color for some resion.

Bump. someones gata know this..
it seems to only do this with the blend material. i havnt tryed all the marerials.
top botom works fine

It won't render correctly.
This is a limitation of the blend material and also of the composite material.

It is explained in the max help as follows.

If the object has a Composite or Blend material applied to it, only certain elements render correctly. Which elements render correctly depend on the renderer you are using.

The default scanline renderer renders only these elements of a Composite or Blend material correctly:

Diffuse color
Specular color
Reflections
Ambient color
Self-illumination color
Refractions

The mental ray renderer renders only these elements of a Composite or Blend material correctly:

Lighting
Shadows
Normals
