Hey sorry I just noticed this! @electronstudio Please make sure you have applied all transforms to the model. I've ran into this same issue, and applying transforms before exporting can solve this issue.

@Gamerfiend thanks for the proposed solution.

Note to others who may come across this issue.

I just stumbled upon this issue after my mouse ray mesh collisions weren't working as intended. It turned out, that the ray checks collisions with the original GLTF model, but not the scaled model which is drawn (this also includes the fact that the transform does not change when drawing the model, as well as the rotation), hence the model is always at the center of the world coordinates. to compensate for this, ensure you update the model's transform matrices (example below written in odin).

            transform := _unit^.model.transform
            transform[0][0] *= _unit^.modelScale
            transform[1][1] *= _unit^.modelScale
            transform[2][2] *= _unit^.modelScale

            transform[0][3] = _unit^.position.x
            transform[1][3] = _unit^.position.y
            transform[2][3] = _unit^.position.z

Also, just wanted to say...

I LOVE THIS LIB SO MUCH OMG <3 <3 <3 GREAT WORK @raysan5

I ran into this same issue, doing Ctrl+A in Blender to "Apply all transforms" fixed it. Thank you @Gamerfiend

Worth noting other 3D viewers are able to to handle the scaling just fine.
