ray tracing with > 20 millions facets ?

[sonno]

Hi,

I've created many photogrammetric models with Metashape. Some are of the order of 10 million facets, others 150 million facets or more. Now, I want to calculate ray traced renderings. I have no problem importing 10 million facets into Blender, but even the latest versions of Blender crash above 60 million facets, for example. I can of course decimate the models, but I lose rendering finesse & nuance.

Do you know a way of importing so many facets into ray tracing software? Do you know of any software capable of rendering models with over 100 million facets without the need for real time rendering ?

Bests regards, David.

So like a normal map?

maybe unreal engine 5 (nanite)?

Hi, I tried with UnReal5 on a 132 million facets mesh model and 16 x 4k textures. It imports the OBJ 3D model and texture file but I think nanite still decimates the mesh. But it works. It takes a lot of time to export from MetaShape and import into UR5. UR5 doesn't have a stereoscopic camera like MetaShape. Ideally, this feature should be added to MetaShape.

Most rendering engines allow you to bake into proxy geometry such as VRay vrmesh,
