Hi all. I have realized that neither GLTFExporter neither GLTFLoader are able to export|load scenes using InstancedBufferGeometries. Is there any plan to add this functionality to them? Best regards

[image] Alejandro_Insua: Is there any plan to add this functionality to them? No because it’s usually not the responsibility of loaders to care about instanced rendering. This is something the 3D engine (in our case WebGLRenderer) should do automatically. Such a feature is called auto-instanc…

Hi Michael. Many thanks for your feedback. Best regards

Here’s a snippet I’ve used before to convert a model loaded from GLTFLoader into an InstancedBufferGeometry – donmccurdy/three-shadenodeloader/blob/9086f85eda800424d6cd446b5412e98ed97591b4/index.html#L307-L322 function makeInstances ( geometry, material ) { const instanceCount = materi…

Hi Yes, sure I am interested. : ) I will have a look. Many thanks. By now I have also implemented my own culling system for instances using webworker technology. By now I am able to see 50k meshes, 1M instances and more than 1000M vertices | 640M triangles in a normal PC. I am quite happy but…

I need to add this is part of a commercial project. [image] Alejandro_Insua: culling system for instances using webworker technology You perform culling asynchronous? Culling is required to be synchronous with the current frame, otherwise objects pop in/out on screen.

Hi. I used SharedBufferArrays. Best regards

It doesn’t matter actually if it is a shared buffer, culling is part of the render process and should be done synchronous right before the render list generated from that process is rendered. Once the frustum changes fast and the worker gets out of sync. objects will pop in/out suddenly, this effect…

Hi. Sorry for the delay, today I was working on other topics. Maybe the problem is that I didn’t explained my solution with many details. In deed, my solution used 2 levels of culling. As you has hightlighted, the real culling is done on the main thread (in the render loop) based on a culling di…

If you’re interested, i’m releasing the IndexedVolume component next days, it doesn’t only accelerate the culling phase but also provides auto-instancing (with culling), the impostor plugin will follow later.
