Hi I am new with Octane, here is my first rendering and my first question, how can I get rid of all the noise made from the orange emission texture?

For your first attempt, you sure seem to know what you're doing! Very nice.
You can also increase the sampling rate on your emissive materials.

Also, What kernel are you using?
PMC with caustic blur of 0.01 is probably a good place to start (if you aren't doing this already!).
If the light goes through the glass of the tubes, then it is a caustic, so caustic blur should help a lot.

Thanks
Chris.

Here is my 2nd attempt, I decrease the texture emission distribution to 0,0005 and increase the sampling_rate to 50. Is there any advise what the best sampling range would be?

Usually I use Vray but decided to give Ocatne a try and its really amazing - the workflow is unbeatable. To work like WYSIWYG is the way to go. I was worried about the material editor, which doesn´t work well for me in the demo, but now in the full version its perfect.

Here is the same tube amp in black&silver...this time I used Path tracing with caustics blurred at 0.09, the tubes have a spec_mat with fake shadows. Does fake_shadows make the light goes through glas? How can I controll if light goes through glas or not? I use 3ds max....

Very neat. I think the bump texture on your front panel doesn't tile properly, there are vertical streaks at regular intervals or is that on purpose?
And you are definitely right, Octane is a fantastic engine.

Yes, I know I was to lazy to change it to an tileble in PS.

Octane is really cool, I start to do some animations for my next fair I have in april. Octane is such an amazing beast...

You can check out my animation when it done here at http://www.gartenlokale.com ;-)
