As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
The UVs for your quad look correct. For your rotating arrow or other objects, where are you stuck in the procedure that you linked to?
By the way, for correct lighting and correct behavior with some 3D object filter nodes, you'll need to fix the normals, tangents, and bitangents into the Parabox Make Mesh with Values node. Maybe you're already aware and just filled them in real quick for this experiment, but I just wanted to make sure you knew they should be different than positions.
