Meshes with the same geometryId for different shapes

hi, i have two model in wich some meshes have the same geometryId for different shapes. When i try to import this models in my scene the first imported model work fine, the second imported model has the shape of the first. If i put different geometryId in the .babylon files every models work fine. My question is if there is a whay for reassign the geometryId for a mesh on loading in scene or if i must modify it in the source file .babylon.

There’s no way to reassign geometryId at loading time that I know of, so you should better do it directly in the .babylon file indeed.
