Texture rendering black - but no alpha channel

Anonymous — Sun, 21 Jun 2020 17:34:43 GMT

As the title says, I have a texture in a scene rendering black, no matter how brightly I set my lights. I've already searched the forum with keywords, and I found various solutions that worked for others in the past, but haven't worked for me yet.

The texture is an aiStandardSurface, not a lambert or anything of that lot. Tried checking the normals; Display > Polygons > Face Normals shows me they're all facing correctly. I've tried checking texture for an alpha channel in PS; already removed. I've tried making sure the texture points to the right folder and file; goes to the sourceimages folder and correct albedo. Tried making the texture a .tga and .jpg, both with equal success - none. I've tried making sure it was saved RGB and not CMYK; it was RGB. I've tried cranking up the exposure and intensity of various lights and of the texture itself; no luck. Even tried cranking up the Emission value; it still shows up black, though it's reflection underneath on the surface underneath is super bright.

I would really appreciate some thoughts on the issue, thank you.

(The pumpkin, if that wasn't clear)

Re: attached .ZIP, I had to delete all the .PSD work files to be able to upload this, but the textures are still there. The latest iteration is hauntedhallway_mb02.mb

Hi!

Thanks for the scene-file, this made troubleshooting a lot easier.

For the pumpkin "Matte" rendering is enabled.

In the shape node in Attribute Editor, arch_stairs_pumpkin_geoShape:

Arnold > Matte (uncheck)

or simply execute this MEL script:

setAttr "arch_stairs_pumpkin_geoShape.aiMatte" 0;

Thank you very much, that clearly solved it. I never would've found that, no clue how it got checked on in the first place.
