Everytime I hit render, I get a different output
Hi there,
Every time I hit render I got different output — the shadows differs dramatically. And sometimes, instead of shadows, some strange glows appears in unexpected places.
There is just one white material applied on all the boxes (big and small). Somewhere there are strange reflections, somewhere extremely dark shadows. But in new render these “errors” changes randomly — they appears on different places.
I use Physical render, GI is on, no AO. Scene is lit by HDR image.
What are those artifacts? And how to avoid them to get exactly the same result in each render?
Thank you in advance!
