Mia material x passes problem

[frack]

Hey, when I plug in a file into the colour channel, the material gets blacked out, in the program itself, not just in the render. This happens with any file. However no  problems occur when I use any maya software shader. Whats causing this? Also is the a setting that one can change in the batch bake options for ambient occlusion to give more coverage in order to reduce areas of total black and spotted areas?

Well the texture problem I would assume has more to do with the type of file you're plugging into the MIA material, it may not be supported... tough to tell from here. as for the occlusion texture node... I believe the setting you're looking to change is the spread. By default it is at .8, but if you up the number it will spread the black further out and make the "shadows" lighter.
