I have this issue with geometry that has Ptex on it getting garbled once I merge the objects, even though individual elements render fine:

back when the Maya version was out of date, I wrote a script to do a similar thing just by dragging and dropping exported OBJ files onto the ZBrush app in macOS since that imports the mesh. I don't know what sort of interop you need but that type of thing is easy to write for Houdini since you just make a drag and drop of your geo the post-render script action. Try the attached scene – it works for me. You might need to change your path to ZBrush in the geometry ROP's script since I'm using floating license version that has a different path

there's a render log for the job. Most often it's a permissions problem since the hquser doesn't have write permission to the share.

I've created another floating window to view the scene but when I template an object, it only appears in the original viewport. Wondering what I'm doing wrong here.

I'm wondering if there are newer builds of Houdini Engine for Cinema 4D that support H16.5? It seems like there's a separate cadence of releases for C4D that's lagging quite a bit so maybe this is something more on the Maxon end.

Hey, Just going to add to the noise here… It's so damn frustrating! My wacom has been acting out lately as well and I was still using Sierra! I just updated to high sierra yesterday in hopes of better support but nothing! Even with the new drivers it's still finicky and I can't tell whose fault it is anymore.
It's the Wacom driver. Use version 6.3.15-3 if you can. There are some regressions with 3D apps and middle mouse click after that driver.

this is what I do:

It works a lot better for collision since you can have things skate over the surface naturally that wouldn't work for vdb method

Technical Discussion » how to create stream of particles from single particle positions over time and create curve from particle positions?

feels like a basic thing but I'm not sure how to get a series of points from a single emitted particle's position over time and create a curve from the points.

thanks but there are no textures or HDRs referenced in the scene and, like I said, it renders fine when I launch Houdini on the same machine and render from there.

I should note that Hqueue shows the job as executing successfully even though the image is black

Now that I have Hqueue rendering, I seem to have a different issue. The machine can render to file fine but when I try to do it via a submitted job from another machine, the image is black. I'm guessing it might have something to do with the hquser since the local Houdini interactive render that works is done with a different account. Thoughts?

why can't you do the same thing on one machine for max efficiency? Or can you do this?
You can do this. It's even how I often test distributed sims without needing to wrangle lots of hardware. But if an algorithm can be distributed, it is a much easier task to thread it. So most of the time if you stopped getting any returns with more cores; you are not going to get any more returns using more threads.
Historically, there was a notable exception to this. I had so poorly implemented the SPH multithreading that distributing 4 single-threaded versions on one machine was faster than running a 4-thread simulation. FLIP and Pyro are much better implemented, however, so I would be surprised if you got any improvement by distributing within one machine vs using multiple cores.
Right – this was where I was confused I guess. It wouldn't make any sense to be able to distribute a sim job since it wouldn't scale there for the same reason you wouldn't get gains locally with a lot of cores that showed diminishing returns.

I guess what I'm saying is, let's say you have a scene set up – it's not going to scale to 12 hyper-threaded cores on the host machine so that's why you divide it up for distributed solving but wouldn't it just be as valuable to find the max efficiency threshold of threads for a solve and divide up into buckets for the host machine the same way?

If you have a FLIP or pyro solver that doesn't scale well but it can be divided up over many machines to divvy up the work, why can't you do the same thing on one machine for max efficiency? Or can you do this?
