Hello forum,
i'm new to Octane and it's my firt post. I tried to find an answer with the search engine, but didn't find anything.

I need to create something quite simple : a pink neon tube light, using octane renderer in C4D.
Octane render : 2.06.01
C4D : 15 057
windows - Geforce GTX 680

I use a simple cylinder, made a diffuse material with texture emission.
texture : I put a rgbspectrum, pink color
power : 80
(I don't know what to do with distibution)
and the result is ugly. Instead of having a nice pink glowing neon tube, I have a very noisy pink/white texture, without glow

Thanks for your help

Hi,

To get the effect You're after try not to make simple material, but mix with specular glassy look once You nail down the llok use some lens effect (post production tab ) to get glow - depending on Your scene this might give the best looking and most photorealistic look

Thank you for your answer.

I want a quite simple effect, like this image found in a tuto for octave V1

I tried to follow the tuto but the result I have is that :

Hi!

Is this the result you are after?



I think you did everything correct besides the octane camera settings. You need to have post processing turned on and increase the bloom and glare power until you get the desired results.

You can download the c4d scene from here: https://dl.dropboxusercontent.com/u/254 ... n-tube.c4d

If you are looking for a more realistic glass tube use mix material as glimpse was saying.

Use Gaussian Spectrum Node (instead of RGB sepctrum), then Color Correct Node for the saturation levels, then patch that into the distribution of the Blackbody Emission node.
