  1. Redshift Volume Emission Problems

    Hello Atom, thank you so very much, I got it working now. Apparently all the tweaking in the world is useless if you ignore the fact that there are two more parameters with slightly weird names!
  2. Hello fellow scientists,I am currently working on a shot where I want to render out an indoor-explosion over about 50 frames. Now since I can't get my mantra render-times below 20 minutes (in FHD) I had hoped to render the volume in redshift more quickly because I have had good experiences with rendering just density in RS.The problem comes up as soon as I start to use emission with redshift. I start to get very weird boxes of emission around the edges of my volume (it seems to be like 16 cubed boxes of voxels reminding me of compression.) - screen attached. Screenshot_50 has about the look I want to achieve, but with this weird halo. When I amp up the emission, the boxes become apparent.Not sure if I tried switching to VDB to render, but I'm not hopeful that would change much.Has anyone come across this issue before?Attached is also my hipfile with the way I set up my render and one cached frame so you don't have to sim again. (Including my approach to an indoor-explosion for anyone who might learn something from that - please do!)I would really appreciate any thoughts on this. (And if my decision to move away from mantra in this case is actually remotely sensible - I'm really unsure.)Thanks,Martin Grenade_RnD_v20.hip
  3. Render ROPs in background

    Hello! I have a question concerning ROPs, because I can't seem to figure out how to render them "in the background" as you can do with other write-to-disk SOP-nodes or Mantra-render-nodes. I really like this options as it gives me the ability to still work in the same scene without having to open another window. My particular case is that I have a flip sim and want to render two caches out at the same time (one fluid cache, one surface), frame-by-frame dependent on each other. If, as I expect, you say that there is no way to do this, because of the dependencies, then I'm fine with that. I just wanted to ask if I missed some usual Houdini-black-magic. Thanks!
