Would plant studio do the job? I downloaded a tall grass object which at the viewing distance would satisfy the project needs. It is in a square and is a clump of many stalks. I put a post here asking if it could be reshaped into a circle to fit into the model space allotted. Creating wheat heads from photos seems like too much detail for the scene. They will not be seen as closeups, but from 30 feet away or more. LARRY
