Errr... hmmm... OK, I gave up. Maybe I can add the myst like the steam, by using another Image as Plane. And renounce to the composited fog.

| Mar 12, 2015 at 17:02 | comment | added | Phantômaxx | No... Only the closest to the observer was rendered well (greyish). The other ones are blackish. And pixellated, too. I think I'll give up. | |
| Mar 12, 2015 at 16:52 | comment | added | Phantômaxx | Sounds interesting... but now I need to follow a tutorial on overlaying layers in post production. Just wait about 10 minutes, I did a render but I forgot to assign the new material to ALL the steam columns. I did just 1 and it was PERFECT (but I don't know if the mist arrives to touch it) - doing it again. And crossing my fingers. | |
| Mar 12, 2015 at 16:48 | comment | added | Jaroslav Jerryno Novotny | @DerGolem What about moving the smoke to separate render layer and then just alpha over it in post-pro? That should be the easiest option. | |

Now I swapped Z-Depth and Transparent. And it renders well! Waiting for it to finish to see if compositing ruins it again.

| Mar 12, 2015 at 16:36 | comment | added | Phantômaxx | No. Now it's giving a bad looking material during rendering also. | |
| Mar 12, 2015 at 16:34 | comment | added | Jaroslav Jerryno Novotny | @DerGolem The custom z-pass for the fog went well? Is the issue in the compositing nodes? I can't look into your .blend now but later will inspect it. | |
| Mar 12, 2015 at 16:30 | comment | added | Phantômaxx | Well... unfortunately it's even worse (not that it was beautiful, before). Now I end up with an inverted Alpha (where it should be transparent is greyish and where it should be white is transparent). | |
| Mar 12, 2015 at 16:29 | comment | added | Jaroslav Jerryno Novotny | @DerGolem Well you don't need any lights for this material - the front will be shadeless white (emission) and the back will be black(no material there). You can also input the shaders the other way round for inverted result. Then you just play with farpoint and contrast to adjust the mapping. | |

OK, done, trying to render an Image-Plane with this new material... Emission instead of Diffuse? How funny! But maybe it's due to Cycles youth?

Is Z_Depht a standard node in Blender? And Group Input? I guess I never noticed them, before. As I said, it's only 4 months I started with Blender.
