So you clicked on me... Mwahaha! I'm Aaron a 3D artist with a passion for modding and games, generally known for being a tad random and a bit drunk, If i'm not out getting the kids off my lawn, im usally modeling or managing content on modDB. Your welcome to message me about mod, engine, group or forum issues or just drop in for a beer.
Never touched displacement modifier, however misclicked on my last model and used it for the roof, that got me thinking for sci-fi walls and panels, the system works fantastic for making a high poly detailed wall, and swapping down the amount of poly on the base plane mesh for your low detail game model.
I'm sure people do this all the time, but as i've never used it, keen to show some basic results.
