Your atlases 3D model is often distorted due to UV unwrapping errors, incorrect scaling, or incompatible file formats.
UV unwrapping issues (like overlapping or stretched UVs) misalign textures with the model’s surface, while wrong scaling in your 3D software or during import/export can stretch the model itself. Incompatible formats (e.g., exporting from Blender to a game engine without proper settings) also disrupt the model’s structure.
Try checking UV maps first—use your software’s UV editor to fix overlaps. Reset the model’s transform (e.g., Blender: Ctrl+A > Apply Scale) if scaling is off. Test small exports to confirm format compatibility before full workflow steps.
