In 3d you will probably not find it anywhere. I have a wheat field behind my culinary herbs garden (the field is not mine). They are already ripe and looks like the image above. It would not be difficult to get some stalks and take a photo of it, you could then use them as alpha planes in Vue4. But I need to know if you need 1 stalk (or some stalks) or if you need a photo of a bunch. Let me know. Guitta
