Hi Lemonade,
thanks for the advice. Screens with unwrapped UVs is a good hint (i forgot about that).
I am new to selling 3d assests (not to doing 3d ...) and i decided to go with cgtrader as i liked the community approach.
Today and tomorrow i want to finalise a special wood object for the PBR challenge: maybe a set of chairs or a room divider that i am working on... Not sure yet.
thanks again for the answer
