eunchae Posted April 29, 2020 Share Posted April 29, 2020 Hello everyone. I made an explosion. I am rendering it at Arnold. However, I want to apply rest noise to temperature, but I am not sure how to do it. Inside the shop, I created the arnold shader as shown below. And I tried to apply rest noise. I don't know if I do this, but ... Rest noise doesn't seem to be applied, and when you just apply noise, the noise is broken. I want to make noise naturally, what should I do? Please help me. Thank you. Quote Link to comment Share on other sites More sharing options...

eunchae Posted May 14, 2020 Author Share Posted May 14, 2020 (edited) Is there anyone here? I tried using the color correct node in the Arnold shader. And how do I make the volume indirect brighter? Thank you. Edited May 14, 2020 by eunchae image is broken Quote Link to comment Share on other sites More sharing options...
sant0s81 Posted May 14, 2020 Share Posted May 14, 2020 Didnt use Arnold for a long time - but cant you just plug a noise into the volume displacement? Arnold docs give me that: https://docs.arnoldrenderer.com/display/A5AFMUG/Normalized+Noise+to+Volume+Displacement Quote Link to comment Share on other sites More sharing options...

Again, didnt use Arnold for a long time - but I guess, its quite similar to Redshift Volume Shader. You can use a ramp with different colors to the emission channel (heat/temperature) for example and than use density and absorbtion channel to modify density. Also play around with remap range.
