PBR and textures with alpha channel (1.31.0.12)

I have noticed that with the 1.31.0.12 release and PBR enabled, any object with a face having a texture containing an alpha channel is completely invisible. This can be demonstrated by rezzing a cube and then setting its texture to the Library's White - Transparent (semi-opaque). In version, 1.31.0.11, the cube will render as expected as a 'ghostly' or 'smokey' partially see-through cube. In 1.31.0.12, it is completely invisible. The behavior shows up with shadows enabled, either sun & moon or all.

Re: PBR and textures with alpha channel (1.31.0.12)

Yep, a consequence of one of the latest (not yet released) "fixes" that went into LL's PBR viewer, and that decreased the usable number of texture channels (mainly for macOS issues). Reverted for next release.

If you compile the viewer yourself, here is the patch to apply to current sources:

Re: PBR and textures with alpha channel (1.31.0.12)

Thanks for the patch. Even though experimental, I have been using PBR pretty consistently. I know there is little to no content in-world yet, but figured I'd help knock out any issues before wider adoption.
