Trouble Loading Door Mesh from GLB in Babylon.js

Hi, I am a newbie and have a question about mesh loading. I created a room and a door in Blender and exported them as a GLB file to load in Babylon.js. The room loads perfectly, but the door doesn’t load correctly and appears as a block mesh in the Babylon.js sandbox. Could you please help me understand how to solve this issue? Thank you.

Of course, we will all be happy to help. But you will need to share the model or a playground showing the incorrect model, of course. playground is at

This link may help with PG creation - Babylon.js docs

Note, common problem here is that the root node of imported glb is a transform node and doesn’t have any geometry associated.

I just have created as a test in Blender and import it to sandbox.babylon first. Could u please give me any advice? Thank you

Hello and welcome :slight_smile:

I had a look to your .glb and .blend, you have severals issues here :

First of all, these black artifacts show that you have a lot of faces overlapping, or doubled. You need to clean you mesh to avoid this otherwise the render will be affected in Babylon as well :

You are using a mesh for creating a hole for the door. It’s ok but it was not righly placed. It should totaly go trough if you want the hole to be ok :

As well, you need to export everything but this block. (You can select it, and hit CTRL+I to inverse selection). You need to export with selection only, and as well check the apply modifier, otherwise your hole won’t be OK in the .glb

Then exported .glb is OK in the sandbox or playground :

thank you so much for your explanation. It is really helpful.

Or you can do it here if you’re done with positioning of the door and it won’t change anymore:
