Hi there
I'm compositing onto a tracked grassy background film, and need to scatter some grass (using Forester) into the scene to help a few other 3D assets sit nicer.
No matter what I do with AA samples, Diffuse samples, Specular Samples or Clamping, the grass is just a grainy, animated mess. Single frames look great (especially with SSS, which I abandoned as part of hunting the grain in the animation), but every test animation is just a grain-festival.
Only a single HDRI light, which has 5 samples, and I've set the Adaptive up to 5 - this has ballooned render times into almost unworkable territory, and still no solution...it's really noisy.
Any ideas? Cheers 👍
