nicoladanese Posted February 16, 2018 Share Posted February 16, 2018 Hey I'm having some troubles getting reflections of a pyro sim into a ground plane. everything was just fine, then I changed the sim starting from the shelf tool "candle", and for some reasons now I'm not getting any reflection whatsoever, I'm attaching my hip file, if you play through the fast sim and render a frame you will notice the ground is not reflecting the bright fire, and I'm not getting the reason... cheers! debug_refl_v001.hiplc Quote Link to comment Share on other sites More sharing options...
nicoladanese Posted February 16, 2018 Author Share Posted February 16, 2018 look like an issue from the candle setup...even in a fresh scene I'm not getting reflections Quote Link to comment Share on other sites More sharing options...
Skybar Posted February 16, 2018 Share Posted February 16, 2018 It's because you don't have a density volume. The candle shelftool doesn't use density at all in the simulation (no idea why its setup like that). Quote Link to comment Share on other sites More sharing options...
nicoladanese Posted February 16, 2018 Author Share Posted February 16, 2018 awww you're right, if I display density there's nothing...do you have any idea how I can workaround it? I don't want to change the look of the flames though Quote Link to comment Share on other sites More sharing options...
toadstorm Posted February 16, 2018 Share Posted February 16, 2018 There isn't supposed to be density in a candle simulation, unless you want visible smoke. The way the sim is set up by the shelf tool, it's not meant to emit any smoke. I think the reflection issue is just one of angles and normals on a perfectly flat plane. If you use a Bend SOP to curve your grid into more of a curved cyc shape, the reflections work fine. debug_refl_v002.hipnc Quote Link to comment Share on other sites More sharing options...
coltonmil Posted February 17, 2018 Share Posted February 17, 2018 Adding density field and using the temperature as density fixed the issue as well. cmil_debug_refl_v001.hiplc Quote Link to comment Share on other sites More sharing options...
nicoladanese Posted February 17, 2018 Author Share Posted February 17, 2018 both solutions worked perfectly! thanks guys P.S. Colton your solution worked well but in my sim I was having a bit of density in render as well... Quote Link to comment Share on other sites More sharing options...
