Hi!
Maxon Support just got back to me — super quick response, fantastic.
They’re aware of the bug, and in the meantime, it seems that simply changing the order in the Render Settings should do the trick. Just place “Redshift” above “Hair Render.”
I’m in the middle of a project right now, so I’d rather not test it until I’m done, but that should work.

Hi there!
Thanks for the answers. I’ll try using Progressive, but probably after I finish the project.
I'll also share this with Tech Support, as @Dr. Sassi suggested.

Thank you

Hi there!
I updated today to the latest C4d (2025.2.0)
And I started having problems with a file I was working on.

I tried to downgrade redshift first, as the error appeared when rendering in redshift but it didn't solve it, the problem was caused by the C4d update, I then downgraded to 2025.1.3 and now it works.

The error is this one:

And I recreated the error in the file attached here:
problem hair.c4d

The issue is simple: you make a polygon selection over an object surface, then create hair there, and try to render: and error appears.

Please try to see if I'm not the only one, I'm now working under 2025.1.3, but I want to upgrade to the latests version as soon as possible.

Thank you!

Thanks for your answer. It's ok, I will do it manually, but it was a great feature, such a pity it was removed. I will make a ticket ;).

Thanks!

Hi!

Not long ago, I used the symmetry tool to mirror an object. I remember it being quite simple—just place the symmetry tool, click (something I don't remember), then delete the symmetry, and I would get the mirrored object.

But in the latest version, I can't find this option. Can someone help me, please?

Thank you!

Hi!
Thanks! I made it smaller, and it works much better now, but it’s still not exactly what I want. I’ll keep trying.

Regarding the field driver, I’m using it with the clones, but it doesn’t look as smooth as it does with the rig.
And everything has to loop...

I’ll get back to you if I run into any other problems (which is quite possible, by the way).

Many thanks!

Hi!
I found this tutorial:
https://cineversity.maxon.net/es/tutorials/siggraph_2017_rewind_ej_hassenfratz_essential_character_rigging

Fortunately, it covers exactly what I need to do, so it's incredibly helpful! However, I’ve run into a problem—please see the attached file. My tentacles seem too straight and rigid. Even when I lower the "strength" or "drag" values, it still doesn’t behave like it does in the tutorial.

By the way, I’m a complete newbie at rigging.

Thanks

Hi,
Thank you so much! Maybe I should go for rigging this time, but I think I’m already in love with the Field Driver. I didn’t even know it existed!

Thanks again!

Hi!
I have a cylinder with a bend deformer applied to it, and I want to loop the bend deformation. I added an Xpresso tag to a null object, using a noise node connected to the bend deformer (strength), but even when I set a frequency of 1, it doesn’t loop at 30 FPS over 30 frames.
What am I doing wrong?

Thank you!

Hi!
Thank you
The video is this one: https://www.youtube.com/watch?v=_c-mARL7JNA
(don't know what happen with the other copy and paste I've used)

It is exactly what you send me in your scene.
I did that, the problem was that I don't know how, I created a "default simulation scene" as a child under Pyro output, and that new pyro killer tag wasn't added to the elements box of that new default simulation scene. Now it works.

Now if I delete that "default simulation scene " and work again under project settings, the redshift material doesn't work...test pyro.c4d

I'm going to try to make that dissipation under the material I think, because is too radical with the killer.
