I have a problem with this scene. Renders only work occasionally (it helps if I press f11 to close render panel then press it again to re-open it). The tiles move about like its rendering but remain transparent and you can still see the checker board pattern through them. It doesn’t take as long when it does a blank render.
If I press animation and try and render out a sequence it never works and the images it saves are blank.
I thought this might be a memory problem (graphics card has 3gb memory) but the same problem happens when i use CPU (with 32gb of ram).
The rendered viewport shading works fine.
Does this sound familiar to anyone?
