v@customColor = @Cd; and read it in shader with RSpointAttribute (ParticleAttributeLookup).
Only guessing RS is getting confused with houdini 3flt(Clr) and regular vector 3flt.

- plug cloud node to volumeslice so you can visualize the density info
- Volume->Interrior Band Voxels.. set it to something like 20 to give yourself enough room for gradient
- Density->Density Multiplier.. set it to 1 so it fits default volumeslice range.. play with density ramp you can see the effect of your ramp

Technical Discussion » White Water RAM usage

Poked around whitewater solver with performance monitor; looks like neighbour creation and killing dead sopsolvers are eating up memory on win10.
Fix that worked for me:
- Edit->Preferences->Object and Geometry->Sop Cache->Cull Level to 4 (this will unload nodes that have flag on)
- Go to /obj/whitewater_sim/whitewatersolver1/position_based_fluid/create_neighborhoods
select all nodes and RMB->Flags->Unload (this sets the actual unload flag you should see little trashcan icon on all nodes)
- bypass /obj/whitewater_sim/whitewatersolver1/kill sopsolver node
this is one is a headscratcher??? setting all nodes to unload had no effect; tried moving deletion into wrangle and bypassing blast sop no effect as well.. only way to stop it from chugging memory was to bypass it.
With above changes I was able to get similar memory numbers on win10 as I was getting on ubuntu 20.04.

yep experienced same thing (submitted bug about it). One strange note.. if you copy/read abc file off a local drive then it's back to being scrubble. Reading off network drive it can take up to a minute to refresh. At first I thought it was our network but there's a definite difference between houdini builds.

If possible post a simplified hip file, it'll make debugging easier (or email support with it if privacy is an issue).
Setting Random Time Offset to a non zero value should randomize the clip time. You can also see what's the current clip time/info in geometry spreadsheet->Attributes: clip*. That will show you all the relavent animation data that is being used.

Take a look at the examples on the Crowds shelf. In streets scene proximity to other agents changes their state from walking to running away; in stadium scene a bounding box is used to trigger a cheering state.
Technical Discussion » Mapping BVH To Mocap Biped?
- AdamJ

See attached file. Mocapbiped (white node) is setup with handle objects/chop to pick up either the targets from the mocap__a or mocap__b rig based on the handle object weight parameter (there's viewport slider linked to it). (note.. handle chop is somewhat finnicky and I've had to split the handles into multiple nodes/groups instead of using a single chop node; and you might have to unexport/export the orange flags on nodes see the rigs update correctly, logged a bug about it).

You can use inlinecpp module for your custom code inside Orbolt assets. Caveat is user will need to have their build environment setup properly. This is easier on linux/osx as they include the compilers; on windows user will need visual studio. Ideally you'd want the user to build the code on their machine. While you can distribute so/dll files with the asset, you might run into binary compatibilities so it's something to keep in mind.

You should be able to use ch calls in your wrangles with copy protected assets (object/sopl level).
Vop shaders are a special case; use parameter vops to create the bindings instead of using the ch references directly.

Make sure your particles have a per particle attribute called ‘pscale’ (it's equivalent to maya particle radius). In the attached file I've added it to the nParticle1 (either add it on the maya side or the realflow side before exporting). If the particles are generated in maya then add radiusPP (this gets automatically maped to pscale by the plugin).

Take a look at clothcapture/clothdeform nodes; they can be used with regular polys and will use orientation into account.

Is there anyone on Windows that's experiencing the sync issues (with latest daily build)?
So far it seems to be isolated to macs/osx.

Houdini 14 should work with Orbolt. We're looking into the ‘Waiting for server reponse’ on syncing assets.
If anyone is encoutering this issue, can you post your specs.. that'll help to narrow things down.
- OS
- internet browser
- houdini version
- python version (if any custom installs)
thanks

Are those errors when trying to drag and drop the asset into network/viewport?
Can you try RMB->Install Asset on the icon and see if it shows up in the tab menu and lets you create it?

This might be useful.. the randomize slider shuffles randomly bunch of parms.. have a look at the callback script for it..
