Hi, we are turning some animated geometry (alembic, non-deforming animation) into clouds, but because we want the noise of the clouds to be in local space (not be affected by the animation), I am trying to work out how to apply the animation after the creating the clouds referencing the intrinsic transform of the alembic. Using an AttributeVOP, I've managed to copy the intrinsic:packedfulltransform of the animated alembic, on to the intrinsic:transform of the static alembic model. I am still trying to get my head around the difference between matrix3 and matrix4 for these transform. Is there a general rule to which matrix type is used in each case? intrinsic:packedfulltransform is matrix4, intrinsic:transform in packed primitives is matrix3, but intrinsic:transform in VDB is matrix4. So what I put together and works for packed geometry or simple volumes, doesn't work with VDBs unless if I pack them before hand. Also my understanding is that intrinsic:packedfulltransform and intrinsic:packedlocaltransform are not writable and I can only change intrinsic:transform . Is that right? thank you
