Nice renders. The only thing throwing this off for me are the repeating textures. We humans are good at picking out patterns, and these are obvious. Maybe set individual texture maps for each element or find a way to offset them a bit and you’ll be spot on.
Thank You :), Yes You’re right about that repeating textures. It’s because truss are made just from three elements, starting, ending and middle which is arrayed and repeated (for modyfying purposes). So far I didn’t figured out how to differentiate Cycles material for arrayed duplicates. Any Ideas?
P.S. I tried to use Object info node with Random value plugged into Vector Math node and then to Mapping node but that didn’t work.
