How to colour vertices of a beveled curve mesh without converting to mesh?

Difference between visual and normal keyframes

I was looking at this question: What do the preferences keyframing options actually mean? I still can't figure out what the difference is between a visual LocRotScale, and just a normal LocRotScale. An in depth explanation would be nice.

Right now I'm working with a mesh, and have several lines that I've marked sharp. Now I'd like to mark seams to unwrap it, however the cyan 'sharp' lines are always on top of the red 'seam' lines, preventing me from seeing my unwrap progress. How…

Are render results hardware dependent?

I have a technical question, which maybe someone with a render engine coding background can answer: Assume we give two PCs with fairly different hardware specs (e.g. one has a dedicated graphics card and the other not) the same blend file. The blend…

A comprehensive list of operator overrides

I feel like I'm always spending far too much time playing scripting whack-a-mole whenever I want to override an operator in one of my scripts. I'd like to build a comprehensive one-stop-shop list for the most used operator overrides.
