Problem: Unreal Engine's built-in Bulk Edit tool crashes when you select more than a few hundred textures. It tries to load every texture into memory at once to build its comparison grid, and your machine runs out of RAM.

TexBatch Method: It processes your textures in small, controlled batches. Loading, modifying, and saving each group before moving to the next. It retains memory usage and stays flat, no matter how many textures you select. It uses the engine's own progress system so you can see exactly what is happening and cancel at any time. It helps to reduce game size and VRAM usage for the final game.


In short, it is a tool to set the "Maximum Texture Size" for the textures in bulk without crashing the engine.
