Title: Inverted opacity in max
Post by: Wigglevigor2 on 2015-03-17, 10:06:06

Hey,
I am getting inverted opacity in max ( I know the image it doesn't really look like inverted opacity but it really is. I should have removed the texture for the example screen shot). I tied all kind of settings for almost an hour now and it always ends up the wrong way around. Checking invert in the output tap doesn't work. Having this issue with all textures the eyelashes are just an example. Can anyone help? :)

can you share the scene so somebody could take a look? Opacity currently works a bit different in Corona w.r.t. bitmap outputs. I will consider changing it in the future, but for now it should be easy to work around this once we see your setup

Corona does not use the Mono Channel for opacity (like Vray or others). It uses the RGB channels. So if you want to use the embedded alpha, try using it in conjunction with a mix map and use the colors to define white and black.

The material/lights converter also has a tool to do that automatically, you can try that and see what it does.

The converter plus some setting changes did an awesome job! Thanks guys! :)
