Bulk Extended is a dockable editor plugin for Unreal Engine 5.7 that lets you apply repeated asset changes across dozens or hundreds of assets at once without opening each one individually.

Designed for technical artists, environment artists, and optimization passes, Bulk Extended centralizes the most common batch operations into a single organized window.

What you can edit in batch:

🔷 Static Meshes : Nanite settings, Distance Fields, Collisions, LOD Settings, Lightmass / lightmap UVs, Section Overrides, and Asset Settings.

🔷 Materials & Material Instances :Scalar, vector, texture, static switch, and static component mask parameters. Copy from parent, clear overrides.

🔷 Textures : LOD bias, compression, mip gen, sRGB, normal map settings, Virtual Texture, and Oodle options.

🔷 Niagara Systems & Emitters :Fixed bounds, warmup, determinism, effect type, sim target, and renderer enabled state.

🔷 Metadata / Tags : Write or remove package metadata across any supported asset type.

For batches over 30 assets, the plugin automatically switches to chunked processing: assets are edited, compiled, saved, and garbage-collected in groups of 15. This keeps memory stable during expensive operations like Nanite rebuilds, Distance Field generation, shader compilation, and texture reprocessing.

The progress panel shows real-time chunk status, a save summary, and a categorized failure list (read-only, checkout failed, save failed, remained dirty) so you know exactly what completed and what needs attention.
