Realistic Neon in Cinema 4D and Redshift 

Thanks so much!!

Ah! Thanks so much!!

Yeah this may be difficult for beginners but hang in there! If you run into specific problems feel free to ask here.

Wow, thank you so much for the kind words!!

Thanks so much! That's great to hear!

Thanks so much!

Whew! High praise! Thank you so much; loved Andrew Kramer's tutorials!

Thanks so much!

Thanks so much!

Thanks so much!

Thanks so much! More in the works!

Thanks for watching! Glad it was helpful!

@@igobyzak do you do private courses in 4d cinema and redshift?

Thanks so much!

Thanks so much!

Thanks for watching! Are you using Redshift to render? The density setting is in the Redshift volume material settings.

@@igobyzak Thanks for the reply! Yes i'm using Redshift 3.0.65. I'm referring to the density settings you're tweaking at 18:34, are they now in the material settings? There are some density options on the "advanced" tab of the volume material, i'll try to play with them, thank you!

Oh I see! I think that Density value is only for splines. A low value will look like spheres cloned along the spline, a high value gives a more solid looking spline, less splotchy.

@@igobyzak exactly) mine looks like the spheres along the line. And what's weird, I don't have this setting on C4d R25, R23, or R24...

I am having the same issue and cannot figure it out

I think it's just a simple HDR for the ambient lighting since most of the light is coming from the emission of the neon.

Thanks for watching! Hmm, I don't think there's any issue with linear fields. If this is for the vertex map are you sure you have fields enabled? Also, have you tried right clicking on your object in the object manager and selecting "Other Tags" - "Vertex Map"?

@@igobyzak Thanks for the answer!

​@@NoDataAvaliable Hi! Can you please share how you fixed it? I have a similar problem.

@@dmitriinizer Hello! Unfortunately, I was unable to resolve this issue :(

@@NoDataAvaliable thanks for replying! I sent a ticket to Maxon support and they replied to as follows: "Your situation triggered a limitation you cannot circumvent that easily. The vertexmaps calculation is done prior the calculation of the Sweep generator, so the change is not seen by the Correection Deformer anymore. In this special situation, you might need to convert the Sweep into polygons and use the vertexmap directly on the polygonal object."

Well sorta. You can change the default black to white gradients in the Redshift volume material under scatter and absorption which will remap the colors based on the density.

@@igobyzak ​ @i_go_by_zak Thank you very much Zak for your answer! Playing with scatter and absorption gradients kind of gives some results. I am actually trying to spread colors along the spline, sure you got me. I guess is not possible with this setup....

@@_acu3470 Ah I see. Yeah I don't think that's possible with a single Volume Builder; BUT! if you use multiple volume builders for the same spline, and fade one volume's density to zero along the spline, and fade a second Volume's builder to zero in the opposite direction, you could blend between two different RS Volume material colors that way.

@@igobyzak Fantastic thank you! It works that way!

Yeah, gotta go into problem solving mode then. One thing to check, if you've renamed your volume builder after applying the Redshift material, you have to go back into the material and make sure your volume builder is in the scatter and emissions slots.
