I have a problem and I can not find an answer in internet. So basically I have a candle with animated candle flame (made with texture nodes and I added a point light source) and I want to render only the flame animation, because other things are static, and then combine the static image with the animated. So I need candle flame to be with a RGBA information. However, when I render it, it gives very weird result. So in the upper part this is how it looks in the viewport, and in bottom part it’s how it looks when rendering.
And it is the same in Cycles or Eevee. Could someone please tell how to fix that, if it is even possible?
