Sunflow works irregularly after first frame processing 1.5.1

in Contributed Library Questions • 7 months ago

Hi,

What is going on with sunflow render after first frame?

Firstly, I have to say that everything with the library is ok, and everything is working.

Smth is not good with the sunflow camera.

After the first frame, second frame is zoomed in. When I tried to zoom out processing camera, I got the same results.

The scene is just simple rotating camera.

Maybe there is a problem that the camera is being rotated every frame?
