    Ahh yes my mistake apologies, I forgot this was using the Vuo triangle patch. (It confused me earlier that you had posted this other ribbon comp here, now it becomes clear). I now wonder if the staggering of the vertices is causing the issue here? I think the basis of my statement is true, when stringing individual triangles together into a strip they need to use the correct point order to ever have the posibility of utilising UV's which display an image accross all the faces correctly. In the sub comp 'Triangle Strip 2Q' which is included here I create the triangle strip vertices in the correct order. It's about starting and ending the following triangles with the same vertex IIRC.

    I realise the Parabox nodes are defunct (They last worked in version 1.2.8), they were the only way that I managed to get the UV's into the correct order for a triangle strip construction, it was in no way elegant and the nodes were causing the gui to slow down terribly while noodling. I just opened up this old comp so I could remind myself how painful it was: I manually created the UV coordinates for 10 sides of a cylinder! eugh!

    Hacky to say the least ;) The order of vertices is wrong, especially for use with UV's. I appreciate the imaginative effort though George. See the diagram that BSS shared in the triangle strip/fan node thread for the required vertex order.

    In my previously shared comps using the Parabox nodes you can see how we need to select and re-order the verts from a single vertex queue, I was always hoping some clever bod would work that out programatically.

    Nice to have your input here @GeorgeToledo. How long ago since the QC ribbons examples you shared on Kineme? I did share a couple of ribbon and cyclinder patches here a while ago: https://vuo.org/node/2680 I also got one going with working UV's using Parabox nodes a couple of years ago, I'd love to see that was possible again: https://vuo.org/node/2416

    Here's the make triangle strip I had in my user modules folder, I hadn't installed the Triangle Fan until earlier this morning so don't have the older version of that.

    Ahhaaa replacing the Make Triangle Fan Object fixed it all.
