Technical Discussion » A process of a node "remesh" freezes

Sorry to tell you, but you may need more physical ram. One thing to try is an attribute delete, especially if you are remeshing at the end of your height field network. Height fields use a lot of behind-the-scenes attributes, that you don't need for final meshing. By deleting those before remeshing, you'll use less memory in the remesh process. There is a dedicated node Convert Height Field. You may want to try that instead of Remesh.

It looks like order of operation, right? The code fetches the value for stiffness, which is 8, multiplies it by the fall off, let say it 0.5 on this frame. That produces a 4 result, which the max function evaluates as larger than 1. The 4 is stored in the stiffness field and gets multiplied by 0.01.
Try resetting the 0.01 to 1.0, and multiply the value of stiffness by 0.01.
Another way to approach this might be with a fit if you want to specify a specific range for the mops_falloff.
Try resetting the 0.01 to 1.0, and multiply the value of stiffness by 0.01.
stiffness = max(a*(stiffness*0.01),1);

stiffness = fit01(a,4,8);

Drop down a new Karma ROP, in case you changed something funky, and try rendering with a minimal amount of samples. Set traced samples to 3 or 9 and disable the denoiser. This might help determine if it is a heat problem, or a scene problem.
If you're not running a fan controller on your 1080, try one of the free ones for Windows. I'm using the MSI Afterburner. It allows you to draw a specific heat curve and dial in the maximum RPMs for the GPU fan.
You could try the nVidia game drivers instead of studio..?

On the color picker, make sure you have color correction enabled. It's the sloping icon on the right.
Apple Silicon Feedback » Karma ROP resolution

Yep, I'd call that a H19.5 bug. It affects CPU/XPU. If you dive inside, the Karma ROP can't detect the camera correctly. The rendersettings node is erroring out. The work around is to unlock the digital asset, dive two-layers deep and manually set your render resolution.

I'm just wondering when we'll see some tutorials covering the new features? Or at least the Content Library updated with examples from the release video?

You need a simulation for that. Check out Matt's de-intersect setup.

Houdini Indie and Apprentice » Proper texture viewport workflow?

You can leverage the Render flag in this case. What I do is keep my UVQuickshade at the very end. I assign the Blue flag to that node, which drives the viewport. Then I CTRL-Click on the display flag on the node above that to move the magenta color to that node. This means Redshift (or any render system) will fetch the s@shop_materialpath from the magenta node, but the viewport will fetch from the blue circle node. The UVQuickshade does overwrite s@shop_materialpath.

Solaris » Karma XPU barely using GPU

After recreating your scene, Karma still produces the same results, near 100% cuda load during render. If you think about it, you want low power consumption. That means a smaller electric bill.

I see Cuda under full load, but 3D around 21%. This render uses the XPU Pyro material node. Can you post your problem scene? Are you using all mtlx materials?

Check which light setting you have activated on the right-side icon strip. You may have lighting turned off?
Apple Silicon Feedback » CPU Usage: Predominantl using efficiency cores for rendering

At a quick glance, "The efficiency cores save power and free up performance cores to concentrate on the most demanding tasks." Perhaps change the power profile of your machine? It makes sense to use the power-saving cores first. Not all of the rendering process is multi-threaded. I see similar usage on my non-M1 system. Half the cores are saturated to near 100% while the others reveal some headroom, not under full load.

It looks like it has been renamed to usdprimvarreader, but what you want to use instead is the mtlxgeompropvalue node.

You can only mix colors, not shaders, so you'll have to adapt your material strategy to leverage that.

$JOB is associated with projects, and $HIP is associated with scene files. You have to reset $JOB if you move your project to another computer. On the new machine, use the File menu option Set Project... Browse to the root of your project and click Accept.

If you haven't set the Grid Scale to 1.0, give that a try, it may improve the overall resolution and limit the drop-off? Surface tension might help with that curved area. You could conduct a test with that option enabled.

This might sound strange, but what if you add a single point light to your scene and set its intensity and exposure to 0 (this avoids auto-headlight creation). This will produce a black, shadowless scene. From there, assign your diffuse texture to the emission color instead of the base color. It's just stars, so the entire scene would be lit by emission.
