Using Alpha channel from .tiff/.targa from Maya to Unity.

Unity Engine
1

I’m creating a large bird cage and instead of loading up thousands of polygons to create the metal bars I tried to create a single texture with alpha channel. In Maya this works fantastic and was easy to do. But when I transfer the object from one program to the other… Not only does Unity not recognize Alpha (creating a white background instead), it doesn’t load the .tiff/targa’s from the source images folder - only Jpegs for some reason.

Also Jpegs with “White Is Luminence” selected does not become transparent.

I’ve looked at multiple guides/tutorials but it’s difficulty to find one that focuses on transfering the qualities of one program over to another…

You should try using one of the Transparant shaders in Unity (Transparant/Vertexlit, Transparat/Bumped Diffuse etc), combined with PSD’s or PNG’s (without a background). As fas as I know, Jpeg’s don’t work for transparancy, I don’t know about tiff/targa.

Sorry for the double post. I wrote the first one and refreshed a little while later - didn’t see it so I assumed it didn’t get submitted. Hadn’t realize new threads are screened first.

I’ll try these shaders and perhaps need to sit down and read the manuel on the subject of Unity Shaders. Thank you for pointing me in the right direction as this has been driving me crazy these last couple of days.
