There is a series of complex meshes with custom texture mapping. I´d like to remesh them with a higher density (ideally quad remeshing) but keep the original texture as close as possible. What would be the best way to achieve this without manually replacing every texture? [Screenshot 2024-11-19 09…

Hi Martin, thanks a lot for the hint. As I did some tests, I can understand what you mean by struggling. But it seems to be the way to go. Let me do some more test and come back with results. I will also look into RH9 gh as you mentioned, since it will be impossible to do by hand. If anyone knows so…

Is there a way to extract the mapping data from this? I could not find any example files for the new components and I am not sure how to extract the texture color from a specific point on the mesh - In my case this would already be sufficent for what I want to do. Or, ideally recreate the mapping i…

This sort of worked, but is to tedious for a large number of meshes. I´d be also fine with just the color information which I could apply to the new mesh in my case.

To get this right on 3D scanned models would need to map the previous polygons that the new polygons of the reduced mesh lies above and then re render a new texture, one polygon at the time. It would be quite the undertaking, but should be possible with some clever thinking. 3D scanned models tend …

I’ve done it two years ago but cant get it to work now [BakeMapping in the Rhino 8 WIP]

It is also possible with Rhino 8, but you will need the Nautilus Plugin: [Canvas at 13;54;17] @martinsiegrist The ShapeDiver plugin has a component that does the exact same thing as your script :wink:

Cool to see some application of my tool. [image] K Popp: The ShapeDiver plugin has a component I don’t have Shapediver but I have the same in Nautilus, [image] I added U and V alone as I sometime use UV as a trick to put Weights on Vertex. I also uses a lot Mesh as a replacement of Cloud…

Rhino 9 has some new grasshopper components in the rhino tab but some projection mappings aren’t available yet…
