Maybe it is possible trough the Custom node: opening the ObjectLocalBounds node you can see a couple of custom nodes with HLSL code like “Primitive.LocalObjectBoundsMin.xyz” (float3), so maybe there is something like “Primitive.LocalObjectRotation.xyz” in HLSL.
I repeat, maybe there it is and maybe not, trying random code in the custom node (LocalObjectRotation, LocalObjectRot, etc…) didn’t give me any success, but still i can’t find online any reference to the Primitive class or any of its fileds…
