like many other posts, I am getting CUDA error: out of memory when I am rendering out many images for an animation.
But- when I close Blender, and restart the rendering process from the stopped image, then the rendering works fine again for a while. This really confuses me- because if the scene requires larger memory than GPU's memory, shouldn't it have an error message all the time?
I am curious- is there a function in Blender rendering, where the GPU memory starts to save and accumulate for a faster rendering? In the attached image- I noticed that another memory number does get larger as I render out more and more images in one rendering session.
Can someone explain what this number is? And how I can avoid this out of memory problem when rendering out large number of images (say more than 3000 pictures)?
