We recommend that 8GB of VRAM is the minimum for rendering projects on Blender. Blender settings Render engine set to Cycles, with GPU option turned on. Alternatively, if you have high budget, you can get a new graphics card or buying a more powerful computer that has a higher VRAM. Methodology / Approach Using Blender 2.93 Alpha, this project leverages 11th gen Intel Core Processors, Intel Iris Xe integrated graphics and / or Intel Iris Xe MAX discrete graphics. Yes, we know that all computers have a limited Vram amount, then the main solution to prevent Blender from Crashing while rendering is to pay attention to that memory statistic at the bottom of the user interface and guarantee that you are working within the limitations of your current hardware. Get larger VRAM to Prevent Blender from Crashing You then can use Video sequence editor to convert those frames into a movie easier later. On the other hand, if you render your file as an image sequence, then each image will be saved as a separate PNG file so all the frames render before crashing will still be saved. Max and Maya are used a lot but nobody uses their internal render engines. Moreover, you will lose the entire rendered file if you render the whole video if Blender suddenly crashes even though you had spent hours rendering the movie before. I so often said Blender is great but it lacks a render engine that is professional. Blender often crashes during an animation render more than it does for a single image. Regarding rendering animations, what you can do is render your animation as an image sequence ( render frame by frame) instead of a video file. It seems like Object Properties -> User Defined Properties had some Vray data in them and it prevented them to export (or sneak peek).
