Make a list and we can explain them. Maybe put them in the wiki for others.
I'm trying to compare the names with the ones in cycles.
One thing, I'm looking for something like colour ramp in luxcore, i tried band but I don't think it is, could you tell me what luxcore's color ramp is? . Thanks

I read them already, in fact I read from Yafarays doc and Appleseed render doc., ..i think that's all I've got to get better.
Thanks
My apologies, I was busier than expected.

And had to notice that a zipped file, with a little more than just a .blend file as a possible default scene, is more helpful as entry point for first users.

And this is why I started defining materials with volumes and short descriptions. Then I will test appending and linking materials to new .blend files.

Actually all easy to do.
But this is often not very readable without understandable naming system.
Not to worry, actually, luxcore is simpler than cycles. Taking my time to mess around has helped alot. I don't think I would be needing those tutorials. I would just post questions that are problematic. Thanks

The first Lux version was based on PBRT v1.0, LuxCore is the grandson of that project so, while it doesn't share anything anymore with the original code, it is still uses the same terminology and approach to problems.

PBRT book is available here for free: http://www.pbr-book.org/

It is a book for developers but you may found the introduction of each chapters quite interesting (in general, not refereeing only to LuxCore) and useful to understand LuxCore.
Thank you, i would read it!!!

There is no directly corresponding node, only Band I guess.

Internally, band is exactly the same as the color ramp in Cycles.
In the old LuxBlend addon they even had the same UI because it was possible there because of special cirumstances. Unfortunately it is not possible to use Blender's color ramp UI in custom nodes without resorting to horrible hacks.

Oh okay, thanks. It did work in some instances but, there were moments it didn’t behave like color ramp. Any suggestions on what nodes I should connect to have something similar to color ramp?

Okay, thanks for the explanation.
I have to go do more reading then. Although, I think i'm over stretching this page with different questions. I should open a new post for different question
