Big Issue with a 3d Model


#1

I have a 3D model with several textures and details that when I open it on Blender it looks awesome, but when I exported to glb, fbx, or even imported into Studio as obj and mtl the model looks awful. Is there a way to fix this? The problem is with the rendering of studio or the problem is with the model itself? I will really appreciate your help.

I can share the 3dmodel with textures if needed.

Thanks
