Thank you Dr. Sassi, for the brainstorming ideas. It turns out that the render farm was not seeing the cached vdbs, and they have to manually go in and fix the c4d file once I uploaded it. They said there's a fix coming for this problem. As always, I appreciate your thoughtful and thorough answer.

Hi Dr. Sassi,

I'm not having good results when sending a file with a pyro simulation to a render farm. For some reason, the pyro renders fine on my machine, but testing it out on a render farm, the pyro does not render. What are steps I need to take? I have read that Alembic doesn't work on volumes. I have cached the pyro simulation as vdb, and I've uploaded all of that to the render farm. I suspect that once in the render farm the file might not be correctly referencing the vdb files. Am I missing any steps?

thanks!
Mike

Ah, that makes perfect sense Dr. Sassi. I thought I saw that it was new, but it didn't quite register with me. Thank you for pointing that out. I will update, but when I'm done with my current project.

much appreciated,
Mike

Thanks Dr. Sassi. i am in the middle of a project, but it will be worth updating. Just to confirm - are you saying that these additional parameters are only available in 2025.2.1?

I'm currently using 2025.1.3

Thank you for your quick reply, Dr. Sassi. I opened the file, and here are the parameters I am seeing in your file for the Look at Camera tag.

Hi. I'm trying to use the Look at Camera tag on some geometry in a group null. The problem is that when I put the tag on it, it gets flipped around 180 degrees in the viewport.

In the documentation, there is a checkbox called "invert," to flip it around so it faces the camera. The problem is that this and most other parameters aren't available in the tag properties in the attributes manager. The only one that does show up is a "change pitch rotation" checkbox. Am I doing something wrong?

thanks,
Mike

It was so awesome, I watched it twice, Dr. Sassi. Please tell him thank you very much for creating that video.

For future reference for anyone seeing this question, there's an excellent video on YouTube on this subject:

[SOLVED] Dr. Sassi, I have found in the documentation under The Node Editor | Redshift Nodes | Redshift Utility Nodes | Surface Nodes | Contour:
"it is confined to the inner bounds of an object. Technically, a contour can never render outside of an object's silhouette but a workaround can be used to achieve a similar visual effect as described in the Contour Behavior section below, Breaking Boundaries." Essentially, I have to add a material with contours onto something in the background. The intersecting lines then render the "missing half" of the line because the lines are only rendered within the geometry. In my case, I put the Toon material on a ground plane, and it then rendered as I wanted it to look.
