Error While Compiling
The Type or name espace name 'meshcolliderbatch' could not be found. are you missing an assembly reference?

You'd need to post under the forum section for the plugin that is failing to compile.

This plugin does not have here on the site, it is mine.

The MeshColliderBatch was removed from Rust, there is no direct replacement that I am aware of. Might be just "Mesh" not, but no guarantees.
