Fix for strange black squares over trees when using blur?
Hello! I have a problem that first appeared in Unity 5.1.1f1 (and next patches didn't helped me). There are some strange black squares which are rendering over Tree Creator trees when I use different kinds of blur image effects with HDR. AA is disabled. Some strange thing: trees which haven't been rebuilt in Tree Creator in 5.1.1f1 don't cause that problem. I tried to create new projects, new scenes, also tried to rebuild the trees again, but I haven't got any result. You can say: "That problem is simillar to white sparkles in deferred path". But no. The issue is same with all rendering paths (suprisingly, with Forward too). Is it a bug or some my mistake? So please, look at the GIFs:
I very need your help! Thank you in advance and sorry if there are mistakes in my English.
I'm having the same problem as well and with similar settings. The weird thing is that it just started happening in the past week or so even though my camera has had the same settings for a while.
Humour me. Remove dirty lens ins$$anonymous$$d of disabling it.

I found a temporary solution. Set the Shininess value in tree materials to 0.15 or higher.

I have a very similar problem. This happens mostly when I decimate some models or use a cloth component. I thought at first that it was because I was using UBER shader pack, but apparently, even using the standard shader gives me the same results.

I have the exact same problem, I think it's something with the Tree shaders maybe

I just had the same problem. It appeared to be because our meshes had some normals with a zero magnitude. Fixing the meshes fixed the problem for us.
