m-egger Posted December 7, 2017 Share Posted December 7, 2017 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 Quote Link to comment Share on other sites More sharing options...
