Memsaver is a VRAM optimization add-on that reduces memory usage by dynamically adjusting image textures and mesh density based on their visibility to the camera. It calculates the necessary texture resolution for objects depending on their appearance in the final render, avoiding the loading of oversized textures for distant objects.

The tool features a non-destructive workflow. Original images remain untouched while downscaled versions are stored in a dedicated cache folder. Mesh decimation is applied via modifiers, allowing users to revert to the original geometry at any point. Memsaver also supports animation by calculating the required image size across all frames to maintain sharpness while still conserving memory.

Additional features include memory estimation for the current scene or external blend files, with output available in HTML or JSON formats. Memsaver provides a preview function to assess optimization effects before applying them and supports UDIMs, image sequences, and the Octane render engine.
