[Odilkhan Yakubov]

Hi. It is still has problem and didn't fixed in any release. It is behavior just with BPT not in other integrators. We must need to fix it.

Hi all,

I've tried the latest build using Bidir and without transparent backgorund the first tile is wrong.

Basic scene, I upload it in case you need (sorry for the colors, it is the filmic addon).

Hello,

Thank you for the info. I've checked previous releases (v3.1.1 and v3.2.0) and this also happens there.

I have an idea of what could be causing this. There are some divisions by zero as well as un-initialized values... Current Bidirectional integrator feels like a coding "mine field"...

I'm working on fixing these issues, or at least to patch them enough for it to work...
