I want to improve overall performance, especially regarding Frame Per Second. If (larger) objects take up more memory, can I hide them and then unload them later in the scene? Especially whenever the camera scrolls/pans over to that part?

To save more browser space/memory, and improve FPS rate, by hiding objects only to reveal them when the camera moves over to that part of scene/level/area.

Example:
In any (2d) game, any assets/objects not on screen is hidden, but when the player moves across a level/area, more assets/objects initially hidden are shown.

Your raptor alone takes up the lion’s share of render calls and tris rendered.

All other meshes are rendered only if they are in the camera’s field of view.

Puzzles and JS. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of meaning at all.

lol, where did you get my raptor file from? So how do I reduce render calls, and triangles rendered as much as possible?

Optimize your model.

And here, and here, and here and in many other topics…

True, but I’m talking about this Petra model

In ideal, you can reduce geometry buffers and render calls for this raptor to just 5 (if you use bones for animations). The triangles count is not so significant.

Thanks for the heads up. Why do bones for animations reduce geometry buffers and render calls for this raptor to just 5?

Reason I don’t use bones for animations is that they’re harder to use, and distort an otherwise mechanical character.

Your raptor consists of 76 separate meshes. One mesh with one material -> one geometry buffer and one render call. Some meshes are multi-material meshes. One mesh with three materials -> three geometry buffers and three render calls. As a result you’ve got 100+ geometry buffers and render calls per one raptor. If you merge all meshes into one mesh and remove duplicate materials you’ll get one mesh with 5 materials -> 5 render calls. But in this case you can’t animate separate parts of you raptor as you did it before. That’s where bones can help.

Fair points, well detailed explanation. Sadly, mechanical parts need to be separately animated, otherwise, will look rubber-ish and unnatural in movement. Like a stretchy cartoon character

You just need to read a liitle more about rigged animations. Any mechanism can be animated using bones.
