Hello,
I'm trying to make some melting cheese with a volume builder/mesher (simplified scene attached), and I'm having an issue with texturing.
When applying some noise to the bump, of course, it does not stick to the surface since every frame is a different mesh with no UVs (you can see mp4 demo of the problem on the link below):

Any idea how to approach this kind of problem?
I know there is some sort of reference space in the tri-planar node and RS obj tag, but I did not figure out how to use it.
Thank you.

Hello,
I'm wondering if there is a way to render an exact background solid color for scenes that for example use GOBO light to light the products and floor around those products.

It's somewhat easy if I use just the dome light, enter a solid color value in the camera background, and use a shadow cache on the floor.

When I use RS material on the floor it caches diffuse and defined color is different.

If I use shadow cacher on the floor I loose GOBO light on the floor.

One way is to play with floor edges opacity, but wondering is there another way to get exact same defined color on the floor and background?
Thank you.

Joke aside, thank you guys for putting so much effort, covering and helping in every aspect od C4D/RS.

All the best!

Hello,
This lesson ends with "in the next video..." but there is no next video in this series.

Thank you Dr. Sassi, great tip.
As I understand, tearing happens on value transitions at the vertex map, so it's better to give sharp transitions between points, right?

I want to make a torn hole on top of the cardboard box, like one in the picture:

Well, maybe I could make it "by hand" but I think it would be nice to try to use Cloth Sym to get an organic feel.
I have to make sure that torn edges look good.

The test scene is on the link below and I think I'm pretty close to getting the hole shape (static mesh) and fixing edges (stitch and saw) on the baked object.
The only problem I have is to prevent some polygons from detaching from the base mesh during the tearing simulation.

yeah, with the new assets database system, there are some glitches and I think it's hard to recreate glitches, especially if we use more than one release of C4D.
Thank you.

Managed to solve a problem with the Connect object (as usual )

But can't get tearing to happen at vertex map guides.
Need some help with this, scene is attached.

Thank you.

Hello,
I'm trying to recreate cloth scene from this tutorial:

Exploding Pumpkin
https://cineversity.maxon.net/en/series/getting-started-with-cinema-4d-simulations?tutorial=10-getting-started-with-cinema-4d-simulations-exploding-pumpkin

But I'm stuck at the step where I need to insert spline clones in the vertex map field at 5:14.
I don't have a spline object option, only Point Object and MoGraph Object.
I'm using the 2025 release, the tutorial is done with 2023.
Is there some change I need to be aware of?
Example scenes are attached.

Thank you.

Hello,
I managed to solve it, not sure how, probably by clearing the assets downloaded cache.
Thank you.

Hello,
For some reason, C4D 20251.2 does not load all of my asset databases on startup.
Every time I start C4D 2025, I need to click Reload Databases, and then all databases show after 2-3 sec.
C4D 2024.5.1 loads all databases on startup just fine.
Preferences/Files are the same for both versions.
How can I fix this for the 2025 release?

Also, while testing preferences, I noticed that some of the Maxon materials I can see in 2025 do not show in 2024, for example, Basic/Clay/Paper material folders.

Thank you.

Thank you for the links, but I guess finding specific topics on a dedicated website like Cineversity would be easier and more convenient.
A little disappointed that it does not work as I can see from forums for quite some time.
I reported it on the Maxon Support Requests page.

Last few days tried to watch some Cineversity videos and noticed that lot of series does not show videos.

Examples:

https://cineversity.maxon.net/en/series/create-with-maxon-master-playlist?tutorial=easy-motion-graphics-templates-2-4-create-with-maxon

https://cineversity.maxon.net/en/series/vfx-and-chill-rewind?tutorial=vfx-and-chill-toon-shading-in-redshift

Reported to Maxon team few days ago but web is still non functional.

C4D Remesh worked just fine, it respects vertex color data so I was able to make low-res model from 7M to 600k polygons (with a pretty good new vertex color map) to work/test renders , and I just switched ON the hi-res model layer for final rendering.
I could use Xref object to have a lower file size working scenes (hi-res model=600MB), but I had no time to test it, I will try how that works.

@Dr-Sassi said in Zbrush sculpted C4D model poly reduction and texture baking:

If you like to animate to a certain degree, perhaps the Mesh Deformer is the way to go, as that can be very rough and allows you to run even heavy models.

Yes, that's what I'm doing, using the bend deformed to bend the head, but it's very slow.
Whenever I select the mesh or it's tags, C4D halts and takes 1min to be responsive again.

Without any idea of your model (Thanks for the link, but that is just a few pictures and some data), I can't say anything about UVs; without UVs, baking textures is impossible.

Here is the UV map screengrab:
https://ibb.co/NmbhxsY

Here is the mesh topology look:

Here is a look with the vertex map:

The provided image texture map is pretty bad:

Remember that 70M (or per link 18M) polygons may provide a smooth edge (all in limits) to small PolyGroups "UV Islands". However, the new low-res mesh can't reproduce those smooth edges, naturally not. Seams will most likely have problems.

Yes, that's why I wanted to bake a displacement map, I'm sure I saw long-time ago tutorial on how to bake a displacement map from hires model do lowres model with C4D sculpting tools, but can't find it again.
I'm sure for displacement that its possible but not sure how the vertex color map would transfer.
Thank you.

Hello,
I purchased this model (C4D+ZBrush format):
https://www.cgtrader.com/3d-models/animals/reptile/chameleon-quaricornis-four-horned-chameleon
The model is ZBrush sculpted and it's heavy to work with (7Mil polygons).
Material is vertex color driven but it has a .BMP color map as well.

I would like to reduce its poly count and bake Color and Displacement texture for use with lower-res model for rendering with Redshift/C4D.

Do you have some suggestions or tutorials for the efficient poly reduction and texture baking process?
Thank you.
