Build acceleration crashes when there's no instances left
Nielsbishere opened this issue · comments
Describe the bug
Accstruct assumes there are TLASes to build, but num_global_instances for that batch is 0 and so it shouldn't attempt to. This results into a crash.
To Reproduce
Fetch feature_rt_accstruct_culling and change scene_graph's rt culling distance to 5 instead of -1. Move around until all objects (except the mirror ball) are out of view.
Expected behaviour
Should just properly cull the objects and not cause any crashes.

Additional context: In master seems to work for culling meshes that are present, but doesn't when they return.
