Volume mesher texturing ?
-
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):https://www.dropbox.com/scl/fi/sd12rdtbmsoylz7lapens/test_Sir.mp4?rlkey=0ugbt05tsuk9zu4llx4ze11tu&dl=0
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. -
Hi Delphis,
The Triplaner might have some advantages, but so far, I haven't seen it used stably on a changing mesh. The Reference procedure is a combination of a Node and the RS Render Tag. It needs to record and then share this data with the other mesh. The simplest way to explain its limitation is that the Volume Builder/Mesher can create holes in an object, which may have no solution on the reference object. This is simplified. I do not see a solution here.
What I did here is use the Loft set up in file …_01.c4d, as it has a stable mesh. Increased the density and placed a Vertex Tag on it. Applied a Random Field to it, and used the Freeze to store it. Random Field off. I did this when the object was not stretched, so the noise looked natural and then stretched when the cheese was also longer.
File …_02.c4d uses the setup from …_01.c4d and shares it as much as possible; perhaps a different map would work better, but I left it as is, as I preferred version 01. You decide, as you know best, what is needed.Here are both:
