Thank you for your answer. I tried this but it didn’t help. Here is mine composition in blender. I’m rendering it in cycles so dunno if that is the problem.
I’m rendering each object on separated layer in blender and than saving it thought this method. I’m going to try render just one object (render layer > alpha over > composite) and I will let you know.
--------- EDIT ------------
Haha … it worked. The software that I was using to put object together has bug with png files and it will make weird outlines to objects. So this composition in upper image works
Thank you and have a great day everyone!
