I’m using hair to render xparticle tracers. I am wondering if I can somehow cache the hair since cacheing the particles makes the hair not see the tracers.
Is there a way to cache hair that has no dynamics?

Hi Shadowgin,

Not to pretend that I’m savvy with X-Partcles, but where did you placed the Hair Material? As I have only a demo version (I wish I had the full version, so much more motivation to learn it then ;o), I hope I got the right set up, as I placed the Hair Material to the xpTrail. See images.

Note, if you copy&paste; from one scene to the next, a typical problem is given in the fact that “Hair” material needs the Render-Settings> Hair. This is not automatically enabled during c&p.

If you have a small (reduced to the problem) scene file, please zip it and attach it here.

All the best

I always feel like I hit the jackpot each time you reply to my posts. This scene isn’t small. I’m sorry but I don’t have a smaller scene to post.
It would take me a bit to build out a small one. Thanks for you thumbnails. Your setup works if using Cinema’s render engine.
Unfortunately I’m using octane and for octane to see hair it’s set up differently. I tried cacheing the xparticle but Cinema’s hair will stay on from the beginning.
I’m trying a couple other things at the moment but thank you for trying to answer my question. Your images gave me an idea that I’m trying.

You’re welcome, Shadowgin. Nice feedback! :o)

What I gathered from (https://www.youtube.com/watch?v=j0XgGgzPuok) was that the Octane Engine needs to be below the Hair—in the Render Settings. No idea if that is of any help here.

Besides that, if Octane doesn’t work this way, perhaps you place the xpTrail into a MoSpline>Spline. Material then to the MoSpline.
If that doesn’t work, perhaps—make the xpTrail editable and if you need to have it growing, set the MoSpline to Separate Segments and use the “End” to get the effect. (Perhaps changing eh direction of the xpTrail-Spline.
However, I have the impression that it might be more complex what you have set up…

The scene was cached, but too large to be attached here. But the set up worked before within C4D. Sorry, there are a “dozen+/-” renderers for C4D available and I do not have them.

My best wishes

No worries Sir, I am always happy for your help. I just learnt how to use octane on this job.
I plan to try your mospline idea. It maybe what I’m looking for. I am in r15 so I couldn’t open your file. I am looking at the thumbnails you provided so it may help. Plus I’m don’t know how to use mospline.
Since the files are being backed up I will have to try the mospline idea tomorrow. I am hoping it works.

Thank you again Dr. Sassi
I hope to be closer to your level in Cinema 4D.

Thanks for checking it out, Shadowgin!

I guess it should be done quickly with MoSpline.
To make that a little bit more visual, I have recorded a one minute clip, so you get an idea about. On the end of the clip, I make it editable [-c-] and render a spline object.

I think to set it up in r15 might be a little bit useless, not having the set up as you have, so far I know, Octane is dependent more hardware configurations than C4D is, but as I said, with all the 3rd party renders it is hard to keep up. Let me know how it works, so someone with a similar challenge will have an advantage (and share something else—later on. ;o)

All the best

Hi Dr. Sassi

I tried the MoSpline idea. Although I think it would work it created too many splines for my machine. I wasn’t able to work while the window was refreshing. Cinema eventually crashed.
looks like we will have to stay on one machine for the render.
Thanks for all your help, I’m sure I will be posting more questions in the future. I was having a lot of fun trying to solve this.

Thanks for the feedback, Shadowgin. :o)

After I ignored the installation tips (the R15 plug in works on my R16, the R16 does not, weird), Octane was running here but gave me an error message “There is no CUDA device which is selected…”, even the newest cuda software is installed here, and I even the plug in found my graphic card (settings).

I really try to get close to your set up, as my philosophy is, a problem not solved—comes back. ;o)

I hope the one machine rendering will be bearable and the result will pay for the patience :o)

Good luck with the project
