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.

Vielen dank! Very informative and useful tutorial. Helped me a lot.

[@gamedevrodrigo]

Amazing! Thank you so much!

Thank you very much !

[@alekseypershin8261]

Thanks man!

[@qazzerful]

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

[@HoudiniSimon]

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?

[@Bugulab]

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