I have a model of a cabinet with animations on it. I had to make a few modeling revisions to the cabinet in Blender and when I replaced the fbx of the old model with the new model in Unity, the colliders just went out of place, and a lot of the interactions are no longer working. The scale seems to not change, it still looks like it fits the environment in Unity properly. I just don’t know why the colliders just went ballistic. And it will be a pain to have to relocate the colliders again. Anyone ran across this issue? These are my settings by the way when I am exporting out of Blender:
Okay so I have always made custom meshes or compound meshes for collisions and put them together in Unity myself. I just learned from a quick Google search that an fbx file can store collision mesh but it needs to have a special name for it to be detected. It could be that when you were editing that you accidentally changed a name by maybe joining meshes or duplicating perhaps.
Here is what Google has to say
Custom Collision Naming Conventions (Unreal Engine): To export custom collision, the collision geometry in your modeling software must be named with specific prefixes, such as UCX_ (for Convex), UBX_ (for Box), or USP_ (for Sphere).
Export Workflow: When exported alongside the main mesh (e.g., MyMesh and UCX_MyMesh), the collision data is stored within the same FBX and recognized by Unreal Engine upon import.
Automatic Generation: If custom collision is not included in the FBX, game engines like Unity and Unreal can automatically generate collision (e.g., via “Generate Colliders” in Unity or “Auto Generate Collision” in Unreal) based on the mesh geometry.
Limitations: FBX generally does not store complex, physics-based data like friction, bounciness, or Rigidbody settings; it only stores the shape of the collision hull.
Another thing could be that you have moved the origin points relative to the mesh and that’s why they are offset.
Hope this helps
thanks for attempting to help…but I don’t understand at alll
No worries can you show screenshots of the problem in Unity and maybe before and after if that’s possible?
