Seems to crash my system whenever outRgbPV is being used. Tried to open any scenes that have this node and output being utilised then using the playback button, boom.

Discovered the bug when building my own scene then confirmed it with scenes from the scene folder.

Activate outRgbPV see what happens, probably an OSX thing, sigh.
(Ive been trying to stuff the rgb array into other nodes to see if that helps hence the arrayToarray)

Heres a working scene that uses an AttributeTransfer than the fluidAttrToArray for color. In the scene in the first post, Im trying to grab the colour from the fluid but all I get are crashes.

Replied to you by email.
Basically everything you need to do is connect voxelGrid.outPositionPP to attributeTransfer.inGeometry.
Disconnect group.outComponents from attributeTransfer.inComponents.
That's all.

This scene is a different issue, please take a look at this one. Just trying to connect fluid colour to copier inRgbPP without it crashing.(sorry they are similar scene names but different) I should also just send them via one medium only ie email or just forum.

This is related to 2d fluids and Parallel Evaluation mode.
I don't think it is on my side, because once i switch to 3D container everything works.
So you can either switch to 3D container (Z resolution = 1) or use DG evaluation mode.

Figured it out. It was crashing because I was feeding the copier node two different point sources - one for position from voxelgrid and one for color via fluidAttrToArray. So different array counts equals unhappy Maya.

None of the scenes with "arrayToDynArrays_instanceGeoToFluidVoxels1" work on OSX. 
I narrowed it down to it being the FluidAttrToArray.outPositionPV in this case.
Created new file setup connecting FluidAttrToArray. > arrayToDynArrays crashes on playback.

Even you feed the copier wrong data it shouldn't crash.
Will take a look and fix.

Also, will check the not-working scenes on OSX and fix whatever needs fixing.

Confirm the bug - crashes in PE mode.
You can switch in the meantime to DG evaluation to get things working again.
Very puzzling bug. Cannot figure out what may be causing it. :S
