I’m trying to render grass.

Been collecting some info from the internet about PBR values for Grass blades/leaves.
Found these:

  • Tall Wild Grass 0.16 - 0.18
  • Short Green Grass: 0.2 - 0.25
  • RGB [0.080219, 0.09084, 0.05127, 1.0]
  • RGB [0.09084, 0.099897, 0.026242, 1.0]
  • Roughness: 0.07
  • Glossiness: 0.5
  • Specular: 0.043734
  • Translucency: 0.1 - 0.3 (yellowish color)

Writing this because was wondering whether these are “good” PBR values, and also to help anyone looking for these resources.

There’s like… a few thousand varieties of grass. Your results look nothing like the Kentucky bluegrass around where I live, though I have seen grass like this before. What kind of grass are you shooting for? And what season?

This specific one is Bahiagrass. Sure there are many types of grass, but there must be some general use reference PBR material values for creating grass leaves.
