  • Unable to import the complete car from blender

Welcome to the forums @UmaShanker!

I have not downloaded the 3D model to look at it in Blender, but my guess is that it is using a Mirror modifier, and when exporting the modifier is not applied and therefor only half of the car is shown. I would check the car body mesh and make sure to apply the Mirror modifier or check the apply modifiers checkbox in Blender when exporting the GLTF file.
