Well here is an image ( part of it , to be more precise )
So...i've been trying to define where those come from but with no luck , i mean it may appear from a certain views and disappear when you get closer. As for kernel - i use path tracing but as at turned out , those appear with others as well.
As for geometry - it may not be perfect but it does not contain any manifold , lamina faces or alike ( as you can see on a screenshot ).
I do have several geometric light sources , thought that maybe it had to do smth. with a sampling , but nope , didn't help.
Sorry if it's smth. completely dumb and noobish , but i've just got started rendering and yep, i may've missed smth.
Any tips are greatly appreciated! Thx! ^^
