An example hip file for terrain texturing.

I'm no heightfields expert so if anyone has a better technique for using hf masks in Solaris, please let me know.

Couldn't you accomplish essentially the same thing as sprites using a particle system with stamppoints in new COPs? You would need to use a PopLookat to the camera, import the camera into COPs...

I would have to think for a sec on how to randomly assign the snowflake images to the particles but should be doable.

OK, so maybe not so clunky after all.

/* ^c* in the Prune LOP worked perfectly once I stopped overthinking it.

I want to render only a collection of clouds primitives called "cloudbank." How do you render only a collection?

Using a Prune set to * -/cloudbank hasn't worked but that's probably operator error (and it seems clunky). I feel like I should be able to point the render to the collection and set a RenderProduct but that hasn't worked either. ?

Shift-F to frame object frames it but then immediately spins the view as if using a turntable. I'm sure this is useful for modeling but how do you turn it off? It only happens in Solaris.

Michael Goldfarb says the same, (paraphrasing) "there's no point to storing rig attributes as points except that Houdini is especially good at manipulating points, etc.

I haven't used APEX a lot but I see your point. He feeds the same rig set up into several characters and the tags handle the different topos. Pretty nifty stuff.

What is the importance of Apex's use of point containers for nodes? Or, why is it useful that moving, adding or deleting the point geometry also moves, adds or deletes the corresponding node?

It is a pretty slick feature but I'm not really sure what to do with it. Is it that graph parity with the node network makes it easier to understand? Or is it a bigger idea down the road, that parameters will be adjusted in Python states so most work is done in the viewport, node parameters being updated in sync?

I think what may get overlooked is that indie developers and artists don't have a lot of resources for debugging their set-ups. It took me a while to understand how to find bugs in my networks that were causing crashes. One example from not too long ago, a material node that referenced a missing material would crash Houdini. More recently, calling an asset from a gallery when the gallery library file was outside the $JOB directory would do it. It gets easier but for artists in studios, the institutional knowledge, and the guardrails put in place by the IT department, help a lot.

To keep this on thread,

More (esp. visual) examples in the docs.

Crowd AI, better intergration into Solaris

Also, COPs, COPs, COPs!!! Robust with AI training nodes ready to go ala Copycat, esp segmentation

MLOPs out of the box

Stable Solaris layout nodes / Solaris integration with COPs

Why do you need a specific AI context tho. Why not just TOP + some AI-related nodes? I'm pretty sure you'll need to call some external python code in the process, so just TOP.

This. Another context is one more place I have to manage in the mental map of what is going on in the shot. I would much rather have fewer contexts and additional nodes in the existing context, e.g., nodes like Copycat nodes in SOPs, TOPs, COPs, as appropriate. Then, train away.

Ari has shown ML-assisted terrains in Houdini a couple of years ago (siggraph presentation or something).
I rmb that. And there was some insane speed increase too. Fingers crossed.

You are talking in the realm of 1% or less of users in your GPU example, QOL benefit to whom?
Just curious, what is your 1% number based on, as it would include all Mac Houdini users?

Since I was diving in to Solaris I did a search about portals in Karma and I found this thread.
Any updates on this?
I see a portal slot on the env light bit no documentation about how to setup this.

Bumping this thread along. Anyone get portal lights working?

Onyro
i want to convert these point attributes to actual groups
Hi Onyro, By actual groups, I take it you are not seeing the groups when you click on the node information? Is your wrangle after the trail SOP? You should be able to create a group from any attribute with the i@group_groupname = 1 syntax. For example, i@group_blueteam = (@Cd.b == 1) ? 1 : 0; sets a points membership to the blueteam group if point's blue color value is 1. Post your hip if you get stuck.
