I use a heightfield_scatter to scatter some instance.
Because heightfield self contain two point,


when use

if (!HEU_GeneralUtility.GetArray3Arg(_geoID, _partID, HAPI_RSTOrder.HAPI_SRT, session.GetInstanceTransformsOnPart, instanceTransforms, 0, numInstances))

HEU_PartData.cs line 776
to get instance pos, the first two instance pos is zero.


Is this a bug or i set something wrong?
Thanks.

Same problem, I took hours to identity this bug, apparently, GetInstanceTransformsOnPart returns transforms started from ALL points regardless “part” index, as a workaround I have to add a “Sort” to have instanced point attributes sorted before other heightfield layers primitives.

I tested on Houdini 17.5.173, 18.0.287, all no luck. BTW, where can I report a bug to SideFX?
