CryptoInstanceID keeps changing IDs even though the geometry and the number of objects stays the same. Works fine when its a simple scene. Starts bugging when the scene gets more complex.


Thanks.

This problem is related to the multi-thread scene extraction feature. The problem is that this feature doesn't guarantee the object's extraction order, so the IDs can change after each reload. To avoid this limitation you need to disable the multi-thread scene extraction in the Octane ROP options.

Hope it helps,
