Day 15 Leap
Something weird going on with the Motionblur but I don't have time today to debug.

Solaris and Karma » Karma XPU on Intel Arc through Embree
- No_ha

When Intel Arc launched I wondered if they will support Intel Embree (the ray tracing library Karma XPU, and as far as I know CPU, uses for CPU devices) on their GPUs as well. It seems that they do now. https://www.embree.org/ [www.embree.org]
I don't own any Intel Arc GPUs but based on some tests, their Ray Tracing performance is comparable with NVIDIA GPUs and they're currently quite affordable, especially the 16GB version.
I'm wondering if Karma XPU will have an easier time adding Intel Arc support because Embree is already being used?
I do not know how easy it is or how different the implementation is compared to Embree for CPU but considering Arc has real Ray Tracing Hardware and is really cheap compared to NVIDIA it might be worth to build a low power render rig with several ARC GPUs, that comes out cheaper than a single RTX 4090/4080. If Karma XPU could use their hardware.
Anybody got more insights on this or ideas?

Day 12 Trees
3 Stage Vellum sim. I'm not too happy with the result but at least I learned something (or how to not do it the next time).

Day 11 Grass
Very quickly made as my actual projects take priority. But shoutout to the Houdini 18 presentation for showing how to copy lights to points in LOPs. (I knew I saw it somewhere and finally had a reason to figure out where)

Houdini Lounge » SideFX License Server issues?

I tested keeping the Houdini Launcher open in the background and so far it seems to keep the license when I render through Deadline or open the GUI of Houdini.
Houdini Lounge » SideFX License Server issues?

Since the last couple of weeks, I seem to have a lot of issues with Houdini Licensing. I am using SideFX License server since 19.5 now and didn't have issues until recently. Anybody else?
Often when I launch Houdini it tells me that no license can be found. It will then open the License Webpage in which I am logged in. If I open the Launcher I am also logged in. Opening Houdini after that will launch correctly. This also happens quite often now when I render through Deadline. Different tasks of the same job just fail because it doesn't get the license.
Another weird thing is, that I sometimes start Houdini and it starts as HoudiniFX, not Indie. I only notice it because I get the message that it will downgrade to a Limited Commercial version when opening my files which are obviously .hiplc
Very weird. I always have internet when these things happen and since I sometimes have the full FX license instead of simply not having any license it makes it seem like there is something buggy happening.
Does anybody else experience issues with this?

Day 9 River
Something simple as I don't have too much time in the coming days.
Just some POPs advected by a volume as curve force was too unstable for this.
And thousands of rocks instanced for the sphere. Rendered in Karma XPU.

USD doesn't really support transient layers (though arguably Value Clips offers this), either a layer is always there or never there. There are, of course, APIs to add/remove layers, but if we consider a standalone USD file/cache, then layers are omnipresent.
This is something that I run into quite often. A recent example was instancing geo that grows (and starts with zero points). I was confused why it would not instance correctly after writing it out to disk until I checked the scene graph tree and saw the prototypes vanishing on the first few frames.
I'm wondering if a good QoL feature would be a checkbox that forces a prim to exist? I ended up having to shift the animation so every prototype instance starts with at least one point, but this might not be a solution that's always possible (or at least not always easily possible).

Day 8 Sand
Used my phone for the Camera movement, Worm animated with KineFX, then Vellum grains on top of a desert terrain all done in Houdini.

Solaris and Karma » Solaris Material Networks hanging when in Manual mode
- No_ha

I encountered something similar. Using a sop import to bring in many particles with packed geo on them. By default it would import them as native instances which meant 8 million descendants in the scene graph. This caused it to hang for each action. But setting the update mode to Manual didn’t help. Each action still froze Houdini for a minute as it was single threadedly working it’s way through the list.

Day 06 Rock
It was quite interesting to find efficient ways to simulate this while also including the inner crystals in the rbd sim. In the end it took less than a minute to sim. The additional debris is actually vellum grains as that was faster than using pops or packed rbds.
Then rendered in two passes with Karma XPU to have more light in the scene for the inner crystals.

Day 5 Smooth
Just some simple, smooth, subsurface-scattered, shapes on Sunday.
Rendered in karma CPU, mainly because XPU still struggles with fine geometry but I wanted to try out the rbd connected faces SOP.

Day 4 Rough
Water/Ice sphere with lots of noises. A couple of crystals were done using TOPs to generate variations.
Retime Instances LOP was very helpful. But missing a lot of procedural nodes from Mantra for shading in XPU/MaterialX. Especially good-looking noises.
Optix Denoiser doing a lot of heavy lifting here.
Uploaded in 4K (not rendered though) otherwise, all details get compressed out of the video.

No outside assets and some struggle with the Layout LOP later:
The gate forms an obtuse angle with the ground behind it.

Didn't have time to polish anything, but it is nice that you can build a good looking glow in COPs.
