Pyro Won't Render

[airline-spray]

Pyro won't render. I've tried using a pyro material and a volume material. I've cached the scene, etc. Here's the link to the project file.

Hi airline-spray,

Thank you very much for the file.

Please have a look here:
CV4_2025_drs_25_PYcs_11.c4d

Start at frame zero, stop perhaps at frame 20, and render.
I have swapped out the Pyro Output, the material, and deleted the Scene Object (it was empty).

Is that rendering for you in that way?
Please let me know.

I do not have the computing power here to dive deeper into it. My machine crashes after a few explorations.

My tip, check with tech support.

All the best

The reason it's not rendering is that you haven't included the Pyro Emitter Tag into the "Simulation Scene" Elements. The simplest solution is to Drag the Cloner's Pyro Tag into the "Elements" Box and rerun the simulation.
Step by step:

1. Rewind, delete and disable caches
2. Select "Simulation Scene" Object and go to "Scene Tab"
3. Drag the Pyro Tag (NOT THE OBJECT) into the "Elements" Box

I had to decrease the sim resolution as my GPU can't handle it, but it did render.

Noseman, Yes, it was empty, so I deleted it, and the rendering worked, as it was applied to the default scene.

My idea here was first to make the setup small and working, as rendering was the main question. After that, check why things are set up as they were. Then explore what is needed and wanted. So we have a good progression and a savvy feeling about it.

So, with two solutions now, perhaps there is confusion for people reading along.

The short answer is: both are correct, while using no Scene Object places it all into the default scene (Attributes>Mode> Scene> Simulation), while using the Scene Object (or more than one) allows creating independent Simulation setups. What is the right one now should be easy to decide.

Cheers

P.S.: thanks for confirming that the scene is demanding, I checked it on several computer here, all show very little responsiveness here.
