Hi there, My name's Thierry
When I attempt to use the higher predefined image pixel resolution settings for renders (anything above 4000 approx) I get a Black screen result in the render window. If I select a lower predefined setting, I will see my render result. If I then attempt to enter my own image resolution values, I get the same results. Black screen above 4k, visible image below 4k. สมัครufabet
