Hello guys!
I have a problem with Corona. I'm trying to put a logo on polygon, but i have problem with the background.
I read many threads about that and i tried everything, but nothing work.
This is what i have done: i put in a Corona material the .png in diffusion ant the alpha map in opacity. I tried to put color read in linear and then i apply that material in the object. I don't understand why i have still the black rectangle in the background.
I upload the image with the problem and what i have done with materials.

Is that a render or just the viewport? If it just the viewport, then there are know issues with the previews in the non-rendered windows.

Ok! In render is better, but now i have another problem! Alpha channels work, but the rest of the cilinder become black!

It appears you're doing it right, but obviously, you have missed one little item somewhere. Any chance you can post the scene? I did a quick test and everything works as it should. The displacement is rough since this is a low-res alpha.

Forgot to ask what version of Corona are you using? Maybe there was an issue in the old version.
