I see, although I knew about that detail during coding, I though you could force it to work that way. Thanks for the info. Thanks, didn't notice the other was locked. That solves my problem.
Hello there. I was trying to use the NormalMapPlus plugin but it keeps creating artifacts (similar to those described in one of the replies). I thought that this might be happening because it doesn't run the whole effect in a single call. So I want to know if there is a way to force PdN to run plugins in a single thread, even if it does decrease performance.
