Nano Tech - Experimental Version 2 with One Billion Triangles Scene

Nano Tech is only a Unity test project, not sure if it will be released, because there are still a few open TODOs to make it feasible. Current features in V2: - One draw call for everything - Async reading of mesh data - Using Unity's HDRP renderpipeline with shader graph and compute shaders (nothing custom) - Using Texture arrays to read textures from all materials. TODOs: - Texture streaming - Full async stream (with cleaning of memory for unused data) - Add Hierarchical Z-Buffer Occlusion Culling to improve performance - Try to use job system to improve bytes to gpu processing (current bottleneck) - Improve LOD mesh data with better/faster mesh decimator
