Missing Rock textures in editor?

ok so when i updated my tools and i got on, all my rocks have no texture except that weird bluish checkerboard texture that you see in the premade map once the devkit launches. It says the texture is missing and i dont know what to do

It’s weird and I don’t know why it hasn’t been addressed as it’s been in the last 2 ADK updates but this is a temporary work-around which should sort things out: Base/Master Materials broken with last update - ARK: Survival Evolved - Epic Developer Community Forums

Check which ARK Devkit Version do you use. It should be fixed in 217.0 and above.

Using the latest version available on the epic launcher (217.0) but it’s still screwed; even after file validation I perpetually get the “MATF_ObjectSnow” errors for a number of different things (rocks, ice, trees, etc.) – currently easiest to just manually edit the parent files and that be the end of it but I would appreciate it being updated to actually-fixed for all of us (as much as I may now be in the minority in that it hasn’t been fixed yet).

Had of been an hour-ish later and you would have had the fix! Haha.
