Fire flies. If this has already been shared some where, my apologies…I just wasn't finding a solution…but figured out a simple and effective solution. I haven't tried this in every different shader. But would assume it should still apply in a similar manner. Like in maya a clamp seems to be a good solution. Kind of nice to put it in the shader instead of affecting the whole scene like MR for maya. So, kudos to houdini. What I did was drop a clamp between the surface model and the surface output. Specifically I clamped the Surface Color or Cf. Now, don't forget this last part…The clamp killed the vibrancy. So I changed the Max value to 2,2,2. This brought back the vibrancy but kept out the fire flies. So, play around with that to find something that works but is acceptable.
