kierensmith Posted June 20, 2019 Share Posted June 20, 2019 Hello, I am needing advice/solutions in regards to my current pyro render in H17. I am doing a volcano plume with some billow smoke, I have a pyro shader sourced into a OBJ merge for my Mantra. I also have a directional light and an environment light that has a 2k IBL. The sampling on my environment light is at 10 and also my mantra pixel samples are at 12x12 and I seem to not be able to get rid of this flickering happening with my environment light. I have looked all all sorts of setting and such changed my HDR to a .rat yet it still doesn't see to remove this flicker. My camera is set at 1080 and is doing a slow pan over 300 frames. Would anyone be able to advise what this may be? Thanks, K Quote Link to comment Share on other sites More sharing options...
TobyGaines Posted June 25, 2019 Share Posted June 25, 2019 Do you know what the brightest values in the HDR are? If they're crazy-high it could give you problems like that. A max value of 6.0 is pretty good - maybe try a max value of 3.0 to see if that solves it. Definitely keep it below 20.0 whatever you do, that's just begging for trouble. Blurring it could also be the answer ; to get rid of hot spots. You'll have to take the HDR into something like Nuke to do this ( did Photoshop ever make this kind of work possible? I avoid it like the plague ) *edit, Houdini has its own comper, maybe you can use that, I don't know how - 10 is really high for light samples - I've almost never needed more than 1, 10 must be super-slow Quote Link to comment Share on other sites More sharing options...
