Hello,

We have created one shoe model and we are exporting it to GLTF format but when we check the file in GLTF viewer, I can see the automatic lighting gets added to the model. There is not lighting added to the the actual OBJ model still when converting that model to GLTF and viewing it on any viewer, e.g. windows 3d viewer, GLTF viewer, I can see white color has got some lighting and due to that white color displays some silver color effect on it.

Can you please let me know if I need to change anything in my model or do changes in lighting?

> SOLVED grinning Hey, when I load a glb model into threejs it is very dark. The problem model is good\_bush.glb. It’s near the bottom of the code. It looks fine when I upload it to [https://gltf-viewer.donmccurdy.com/](https://gltf-viewer.donmccurdy.com/) but it behaves weird with me.
