I am trying to make an explosion in Blender.

I am having a problem with the smoke simulation with the Cycles rendering engine. More specifically, I have been able to render smoke, but flames do not show up. In the viewport however, everything looks perfectly fine.

The render looks like this:

Smoke, but no flame

But in the viewport, it is clear that there are flames. Does anyone have any idea what is going on?

This is NOT a duplicate of Smoke & fire simulation: Cycles material not showing fire because I have Flame Rate set to 1.0

It looks that you've used Quick Smoke. Though its material setup is ready to add the fire, it hasn't the shaders to it.

enter image description here

So you only have to add some nodes to that Input: mainly an Emission connected to an Attribute Node set to flame. Eventually, you would need a ColorRamp to color the fire.

enter image description here


The name in the Attribute box must be without capital letter : flame and not Flame

  • $\begingroup$ This is not the case. If you had downloaded the provided blend file, you would have seen that that's not the problem. There is no Attribute node in the shader so this couldn't be the answer. $\endgroup$ Aug 23, 2017 at 18:27
