Thanks for your reply. Appreciate the support of your free tool.
well. this fault is not yours, its a bug in the mia_material_x. i’ve tracked it down for about 2 hours last night.
here is the bug i’ve logged with autodesk:
using any of the “result” outputs of mia_material_x when it has a cutout opacity of 0 will crash maya when u render.
for example: create a scene. create an mia_material_x. in “advanced” section of the mia, set the cutout opacity to 0. create a surface shader. connect the mia result to the surface shader color. assign to object and render with MR. render begins and then crash.
although this example is kind of simple, it just illustrates the bug. the same crash will happen when u try to utilize the mia_material_x multiple output to write to buffers, and at the same time use textures in the cutout opacity.
