Houdini Tutorial: Closed Sweep Spline and keep UVs

Making a closed Sweep-Spline is easy but assigning UVs makes it problematic because you have to split the curve at one point (like you would create a seam in any other 3D software) and then the sweep-geometry is NOT closed anymore. I show a workaround for that.
The major part of knowledge in this video comes from this Udemy Course. I just added the problem solution regarding the close spline: www.udemy.com/game-asset-crea...

Thank's a lot, I am also following that tutorial :) btw, In Houdini 17.5, we have to use FacetSop. Unique Points can't be achieved by FuseSop, It is moved to FacetSop -> Unique Points.

This is interesting but here's an easier way: run the curve through a "PolyPath" node with "Connect End Points" and "Make Isolated Loops Closed" both checked. This will effectively turn the loop into a 2D shape (possibly if you look at it from the bottom) because all closed loops are considered to be geometry in Houdini. Then add a "Resample" node, followed by a "Smooth" node with a somewhat higher strength (optional). Then add a "Sweep" node with the "Surface Shape" parameter set to "Round Tube", and from the "UVs and Attributes" tab, enable them along with "Override Any Existing UVs". Done.

pretty intresting method, thanks a lot for sharing! and how do you overcome uv strech near corners?

I don't know yet. That could be the next step :D

@@HoudiniSimon This was very useful, thank you. Have you tried to sweep a non-square around the building? It's unclosed at every corner and I keep getting an error saying "Cannot compute the dihedral."

Hi, I can´t get find the option ONE PRIMITIVE AT A TIME. My HDN version is 18.5.462

Circle>Ends>Uvtexture. Arc length spline is not working for me. It doesn't arrange uvs like in video, it stacks them as one point in corner. Do I need to convert them to nurbs before uvtexture?

But the rows and collumns worked for me fine. Thanks for the video! Anyway Houdini uv's are scary!
