After upgrading to version 3.2.1.3 started getting this error when trying to import mesh:

Blender version 3.6.7.
Everything was working fine on version 3.2.1.2, this error started appearing after the update.

For the test, I exported the wall lamp object, replaced it with a cube mesh in blender and assigned Cut 1 (and of course removed the Cut from the lamp mesh).
The most interesting thing is that when Cut is 0, the object is successfully imported.
I will be very grateful for some help.

Hi. I can’t check the file right now but, from your description, it seems like you did not adapt the mesh correctly
Something like a bone or a uv map name is missing

- find a similar maxis item, clone it, export the blend. In the scene there will be an object, one or two shadows, possibly more objects ( for glass, for example );

- append/import/make your object, select it, rename uv map to uv_0. This does not happen when you join meshes;

- ignore uv_1, objects have the same uv_0 and uv_1 maps;

- in most cases the original object will have one or multiple vertex groups. You need to double-click on it to rename, Ctrl C to copy the name ( usually transformBone ), then create a new vertex group on your mesh, paste the name. If there is only one vertex group, switch to edit mode, select everything with A, and assign the whole mesh to it. This is the part that does not happen when you join meshes;

- give the mesh the same cut number;

- you may need to adjust uv_0 if it was not square or rectangular;

- you may also need to vertex paint the mesh if it needs to light up;

- you may need to adjust the meshgroups of shadow underneath the object in edit mode;

- delete the reference, save

Hi NEMAMENE,
Your mesh is missing vertex color that is used by lamps. Previous versions accepted meshes without it, but a change in the last version unintentionally made it mandatory with no good message explaining the problem. The next version won't give this error, but if you adapt the mesh as mauvemorn mentioned, including a vertex color channel in the color attributes (Face Corner/Byte Index if it asks a type), it should import.

Please do not PM me with modding questions. Post in the Creator Help forum.

Thank you very much, it works now!
