No problem here either.
Thank for all the good work (21+ years!).

@Dr-Sassi I meant this one. You use it in your scene.

Enjoy your vacation,
Pim

Sorry, for me it was a follow up question on your scene where you used it.

Restarting ciname 4d and no other app's solves the issue.

I cannot find any info on the Blend (color) Object.
Could you please explain.

Also I do not fully understand the materials using the Vertex attribute.

@Dr-Sassi I am going back to the basics.
Two planes on top of each other (y=0 and y=-1) and both a animated noise and the top one an additional noise for the opacity.
Some questions:

• is opacity the sam as alpha?
• how can i get the original colors in the render
  For example, the red and yellow.
• how can I add a post effect like blur?

Output:

Top material:

Scene file:
simpel v02.c4d

Off topic. Your post is here:

Please new themes in a new thread. Thanks.

Your latest scene is just it!

Now some more vivid colors and perhaps a 3rd emitter.

I also have to look into the Blend object. Never used that one before.

Oke, I will look at it closely, but I think we are getting there.

Note: restarting cinema 4d solved the render issue!

@Pim Here a second example with 2 emitters and with different settings.

But I am still not happy with the 'mixing', with the textures.
Also, the render error is also with this scene file.
