I find it hard to see the details in amongst the wood grains. The grains are great but can hide some of the details. I try to use alum. brass. MDF but still there is a grain. I find I am bouncing from grain to grain to try to see the details
I am suggesting “none” or non grain, just a simple grey tone topographical simulation. light grey to dark grey, or similar. Something so you can see the details better without all the grains getting in the way. Maybe a couple of simple colours, topographical or heat map ish. Maybe these might help a bit to see the details more.
I seldom use the wood grain backgrounds in the simulation. I use Alum for almost every simulation. I agree that most of the backgrounds are way too busy.
And it seems less controllable in the 3D editor. It sometimes shows one background sometimes another. I don’t know if it was based on the last selection in the normal simulation view of if I am just crazy.
