In hou it's really fun and flexible, and most of the repetitive stuff can be automated away. There's almost always a new cool challenge to solve, a creative improvement to be made.
Having said that, there's hardly a part of CG art that doesn't get tedious at times. Modeling, UVs, texturing, animation, rendering... It all has it's repetitive boring moments.
Look at it like at knitting, or putting together a giant puzzle, or playing minecraft. There are moments where you gotta think and be creative, and then there are moments where you can just enjoy the meditative, comforting, familiar process. It can be fun in it's own way.
Also, if things get really boring, you can always listen to music, audiobooks, or your favorite sitcom in the background =)
Thanks for the chat Rayalez! :)
If I want to render a complete scene, I'll put it in "props" or a "set" folder. In it there are folders by software type - hou, silo, ps; and also some for generated files - geo, cache, render, render_comp, and out (for final render).
Also there's CG/assets where I put textures, references, houdini assets, etc.
