Loosing my mind over fire shading in redshift

Help

Hey guys,

Problem:

No good recource about shaping your fire in a shader (at least for redshift it seems).

What would be one of the first things you would like to do when shading fire? REMAP and RAMP the values of the TEMPERATURE-Volume as you always do when creating fire simulations in houdini. But it seems to be not possible.

I cant stand why this is not working, it feels super trivial.

I have created this fire sim and wanted to test solaris for this testproject.

Shouldn't this rsrampscalar basically change nothing?

I have also tried feeding in my own color ramp into the emission tint parameter that would be supposed to be driven by the temperature but no luck on that end aswell...

Is there anybody that could help me out here? Would be much appreciated, thanks in advance!!!!
