When I render a frame where the fire goes beyond the plane and over the background the color goes brighter and unsaturated. This happens only in the final render, not in the viewport render. (pic) Tell me if you need any other information about the material and object settings. final render


export settings

This color problem is what I am talking about: https://imgur.com/a/hY1Y5oC

  • $\begingroup$ I have the background as transparent. In the render view of blender and in Photoshop when added a black background its very noticeable. $\endgroup$ – Vernox Vernax Sep 1 '19 at 18:16

    $\begingroup$ You need to describe what you are seeing better. Provide an arrow to where you are talking about in the image, and where it “seems correct” with another image. Sounds like rudimentary compositing and the nature of emissive yet unoccluding fire / flames, but will wait until you provide more information. $\endgroup$ – troy_s Sep 1 '19 at 19:50
  • $\begingroup$ Oh sry. I thought it was clear enough. I was talking about this. imgur.com/a/hY1Y5oC $\endgroup$ – Vernox Vernax Sep 1 '19 at 21:33
  • $\begingroup$ That’s still not enough information. Show what you think is wrong, and how you are achieving it. $\endgroup$ – troy_s Sep 2 '19 at 2:08

It is not a problem or a bug as you may think - the smoke is translucent/transparent so the light passes through it and you see what is on the other side. In this case - a plane that appears to be gray. Hence the change in color. I guess you could increase the smoke density so the light wouldn't pass through it.

  • $\begingroup$ oh thanks, thats reasonable. $\endgroup$ – Vernox Vernax Sep 2 '19 at 11:34
