Hello everyone!
I’m currently trying to make a minimal gltf viewer that loads from a hard-coded filepath. I can load my object just fine, but when I zoom out, it looks like the object gradually moves behind the background image and becomes hidden. Could someone help me figure out why?
I’m currently using examples/webgl_loader_gltf.html as a template and can view my object just file. So my code below almost an exact match – the key difference is just the object that I’m loading as well as the camera distance settings.
Here’s the object (and hdr) I’m observing this with:
crystal_structure.glb (238.3 KB)
quarry_01_1k.hdr (1.4 MB)

Thank you in advance for the help! I’ve spent an embarrassing amount of time trying to fix this lol.
