Hey,

Yes, this is a broad subject that has been covered a few times throughout this forum with the general direction and idea being consistent with three’s overview [documentation on loading 3D models](https://threejs.org/docs/#manual/en/introduction/Loading-3D-models). This is a great preliminary read in terms of the basic capabilities of _in browser_ model viewing / rendering.

Here are some additional threads that have covered this subject before also…

Copied a key section below: File Size: Ideally less than 5MB. Note that as glTF geometry and texture compression extensions, such as glTF Universal Textures using…

> For large models not only does that not help (you’re not really reducing the size of the memory used - at best it’d reduce the amount of draw calls, but draw calls aren’t crashing tabs, they just freeze them.), it may actually cause more issues, since merging multiple objects into a single geometry prevents frustum culling. So you’ll effectively be rendering absolutely everything at any given moment, regardless if it’s visible to the camera or not.
