I don't do texturing in Rhino. But I am experimenting with it, trying to find workflow that would suits me. I feel I have better control over the resolution and texture quality and more creative freedom in 2d graphic editor.
In Rhino I hint important details with curves on surfaces, unrol surfaces with this curves, sometimes draw auxiliary grid if needed (red lines on last image) and export it to vector editor with separate layers (oulines, paneling, grids, instructions, texts, etc). Then export vecor image as bitmap, draw texture in bitmap editor, import texture to vector image and clip it with original vector outlines (this is maybe redundant step but I like to have it in vector image). I think this is quite standard workflow. I can elaborate on it with more detailes if somebody is interested.
Rhino is excelent for instructions with its tools for making technical drawing from models.
I love instruction images by Julius perdana. He uses textured model for that and it looks cool

. I would like to know his worflow for texturing (eventhou he does not use Rhino). But I am lazy and do not want to waste time on placing textures on 3d model to use it for this purpose
