I have this issue where 3DS Max 2020 runs out of virtual memory when rendering more than 150 frames.
It basically increases virtual RAM when rendering a new frame, and after a while physical RAM just jumps to nearly 16GB and stops with a message "internal error".
The scene itself is low-poly and it's rendered in orthographic projection, using only two low res textures.
It has two lights (with RPR emmisive materials it has four lights); one is RPR's Image based light for the ambient, and the other one is an animated direct diffuse from 3DSMax, because there's a different issue when rendering with RPR's physical light (It increases the brightness for every frame untill the image is fully white.). Is this a bug or am I doing something that isn't correct? I've attached all the files from the trace dump folder (without the bin file because it has over 3GB), I hope it helps in some way.
Scene specifications and render parameters:
Frame size: 1000x1000 pixels
Animation length: 600 frames (30fps)
Min Samples: 256
Max Samples: 500
Noise Threshold: 0.008
Samples per iteration: 2
Time Limit: None
Irradiance Clamp: 1.0
Max ray depth: 3

Thank you for reporting this. I can confirm this is a known issue in 3ds Max. I will provide this information to developers.
