Thank you Andrew.
I have read documentation before even starting the project, and section you have mentioned - additional few times when problems arrived. No solution yet. I’m doing everything step by step, and in shader model 4/5 it works flawlessly, no dark spots with 1 layer at alpha blend and so on. I do believe, that it might be something with my project/world setting. But same thing happens after I try it on blank project. Its about a week I’m trying to figure this out, or work around it and nothing. Pleasae, any help would be just terrific !
ps. I know, 1 layer should be alpha blended to avoid black spots, yet i tried every possible combination with no effect.
