So both the great thing and the unfortunate thing about EmberGen is we’ve built it specifically for rendering volumes, and thus we have a ton of great parameters that are for volumes that most other renderers don’t have. On your end, it looks like you need to continue to play with your gradient mapping. I would say that your gradient is probably too high in temperature and perhaps you need to adjust what range the gradient is mapping to. In EmberGen you can get very similar gradients to what you’re seeing in blender if the temperature is incorrectly mapped.
