Hey all, I recently updated to 4.5.1 and I’ve been trying to import a model for a project but I’ve found that changing the lightmap channel then saving the asset will cause the editor to crash to desktop.
I’ve managed to replicate this problem each time and also recorded a video of it happening here:
Any help here would be greatly appreciated, thanks.
