Hi, I'm trying to do the same thing here, in 18.5.462 this doesn't seem to work. With a locked network, after making the blast node, and the transform node which feed it both editable nodes. When I lock the asset and try to do a group selection, there is no geometry visible to try to select.

EDIT:

Realised it was because I was using python to force a custom preview. Silly me!

Hi B00merang, I have the same problem, everything works fine until I lock the asset. I’ve made both of my nodes (blast and the one that is feeding it) editable but when I lock the hda and try to use the group selection the temp display flag doesn’t go to the feeding node even though it’s editable. Can you elaborate more on how you fixed that?

EDIT: After doing some tests I realized that in order for this to work I had to enclose both the blast node and the null that is feeding it to a subnetwork and then declare that as editable in the type properties of the HDA.

rather than making editable nodes and callbacks which will make your HDA very unflexible especially during updating or if you want to animate your toggle

you can directly reference your toggle value in the Export Parameters parm like this"

`ifs(ch("exportN"),"N","")` `ifs(ch("exportup"),"up","")`
attached example

Thank you Tomas, I always had a hard time to selectively export attributes from VOPs. Very useful trick.

Hi, As we're approaching the summer I think it is the right time to get my hands dirty with sand again. It's a collection of test renders I've made while I was working on a custom sand solver when I decided to move to Houdini about a year and a half ago. Of course with the advent of Houdini 12 flip fluids are much faster plus having access to the built in viscosity and fast point instancing gives a lot more options to play with. Unfortunately at the moment I don't have much time to play with H12 but I hope I 'll fiddle with it very soon. Any comments are welcome!
