It’s time for some Blender compositing hints!
Today I show you how to create a leaf texture, that was taken by a simple smartphone. But we’ll not use a 2D application like Adobe Photoshop, Gimp or Krita - no! Instead we create the complete texture inside Blenders Compositor!
I show you how to do it with just a few nodes and some clicks! Beside creating the texture you’ll get some insights into the compositor, Blenders hidden treasure!
