  • Normal Direction in Alpha Channel not working?

    Posted by Caroline Anthony on September 21, 2015 at 5:47 pm

    Hey all,

    I’m trying to make my model into a transparent alpha mask for the structures around it. I put a material on it, unchecked everything but ‘Alpha’, changed the texture to ‘Normal Direction’ and it just isn’t working. The model comes out solid black. Oddly enough, if I go inside the model and look out the alpha channel works. I tried reversing the normals but that didn’t work. Does anyone know what I’m doing wrong?

    Any help appreciated!

    Did you try unchecking “Invert” in the alpha channel properties?

    Hey Adam,

    Thanks for responding. Yes, ‘Invert’ was unchecked when I first started trouble shooting. It is the oddest thing. I found a work-around for now, but I still would love to figure out what the problem was.
