Just for clarification, Vuo has two types of select nodes, such as Select Output (2) and Select Output (Boolean). The documentation for the first says, "If Which is 1 (or less), it selects Option 1. If Which is 2 (or more), it selects Option 2." The documentation for the second, "If Which is false, it selects False Option. If Which is true, it selects True Option." The type converter Convert Boolean to Integer documentation: "Outputs 0 if the input is false or 1 if the input is true."

Vuo's Fetch Scene node defaults to repeating textures since that's what 3D mesh authors typically expect, but the Change Wrap Mode node can change it to clamp or mirror.

The texture size limit is imposed by the GPU (not Vuo) — see OpenGL Driver Monitor > Monitors > Renderer Info > OpenGL Limits > Textures > MAX_TEXTURE_SIZE; for OpenGL it's typically 16384 but may be less on some GPUs; see also Metal Feature Set Tables > Maximum 2D texture width and height.

Some applications automatically scale down textures that are larger than the GPU allows. Currently Vuo doesn't do that; instead it refuses to load such textures. (If you're interested in that, or other ways of processing textures beyond the GPU limits, feel free to create a feature request.)

We'll look into adding information on texture size limits to the documentation.
