Hey Folks, I am working on a project where I import GLTF and clone them multiple times to display in the scene. I need to access each of this later for a use case. However, this is causing a lot of draw calls per frame (5000-6500) depending on the viewport and hence consumes a lot of memory and re…

You need to create a InstancedBufferGeometry using the original buffer attributes of your model and add a offset and orientation InstancedBufferAttribute in order to use instancing, in addition you need to patch your shader, here is a example pen that also makes shadows work with instances. [ima…

Thanks @Fyrestar , and yes our models have different material and texture so i guess this is going to be complicated than it should be. I will check your merging solution and get back for any doubts that may arise. Thanks again!

Thanks @looeee , checking it out! [image] looeee: This has been discussed previously, see here for a possible solution.

[image] Fyrestar: merge it into one Whats the case with multiple materials and textures on 1 geometry ? is this a problem? should it be 1 geo, 1 material, 1 texture or can you have more materials and textures? so long as its only applied to 1 geo?

Instancing means 1 material, 1 geometry. Textures those passed as uniform.

i made a tool that does this, it takes a gltf and finds similar geometry/material pairs, then creates instances from them [image] ☄︎ @0xca0a auto-instancing went live in gltfjsx 🫠 this was a huge pain in vanilla bc an instance must have 1 geo & 1 material, models aren't composed like th…
