Nice that you found what you needed, and thanks for the reply, Hoi.

My best wishes for your project!

Hi Hoi,

Thank you very much for the file!

Cache Pyro with any forces you like to have it. Then switch off the Forces you don't like to be used for the particles.

Would that work for you?

Or perhaps this one:
CV4_2025_drs_25_PAgr_11.c4d

All the best

That is easy to say about your work, mrittman,

Your passion for details and quality shows, and that is motivational.

Enjoy!

Thank you very much, mrittman, for your reply.

I hope you will have as much (or more) success with your new project as you had a while ago!

Cheers

Hi mrittman,

You're very welcome!

Please keep in mind that many simulation parts of the application work mainly on the Graphic Card. The preview that you get there is what it is, a preview.
In the end, the rendering is the key, and the preview should not be the only guidance for all the project work.

Please check your render settings to switch to Redshift; it is part of Cinema 4D. The Redshift subscription for Cinema 4D would enable more render clients in a render farm.

Please use images of 500 pixels in height; then it should work.
Anything else, please, as Dropbox, Google, WeTransfer, Adobe, or Apple. (No upload of Zip/rar, etc., nor tiny URL, and please no HTML URL wrapper) Based on security, no exception.

All the best

Hi mrittman,

Please have a look here:

The best way would be to ask EJ if the project file is available. As you are not new to 3D, exploring other files might be of more value than getting a "do that" suggestion.

Having said that, please look below; I have changed the Voxel Size in one case (to address your point about it) and the parameter of the Pyro Materials under the Advanced tab for that Pyro Node, which has a much stronger effect. However, finding a balance that fits your art-directing target is key. Please note that changing the Voxel size requires a recalculation. Just changing the value will not change it on the fly. With a cache of the scene, you can upres.

Is that helping?

As a side note, please look into the Asset Browser; based on comments during our shows, artists have found answers to specific questions here.

All the best

Thank you very much for your feedback, eclipse-planet.

Sounds good!

My best wishes for your project.

Thanks for your patience, RemoGambacciani,

How about this option:
CV4_2025_drs_25_MGwc_01.c4d

All the best

Hi appointment-insect,

Just a little feedback:
IT told me that the screen capture is very helpful.

I will update with more as I get new information.

Thanks for the reply, RemoGambacchiani.

Yes, this was even asked a few times during the "Ask The Trainer" live show.

Anyway, please try to minimize the geometry and let Redshift tessellate the results, which might be faster…

As an alternative, could a plane with a texture/alpha help here out?

Cheers
