Looks really nice! I also like the material look.

If I understand the material nodes correctly, I would suggest to not use only a z-component in the dot-product. The sides and bottom look a bit unnatuarlly clean like this.

The dust effect you wanted is now possible in v2.2alpha1.
You will need two of the new nodes from the "Utils" category: Hitpoint Info and Dot Product.
Then you can create a setup like in the attached images.

Well, for these nicessities I am willing to change multi dozen of my former materials.

Scince when does Blender 2.79b render luxcorerender material previews if Blender file browser view is set to icons? I‘ve noticed this the first time yesterday when I appended a former material.
Anybody else already new about it
Anyhow, this is a great feature

And dusting is and other nodes even greater. Thanks a lot.

Sounds good, but I can't get it to work here. Anything I need to enable? I assume you mean File->Append, then open a .blend file and go to the "material" section?

Hmm, well I‘l check at home. As said it was big surprise. Maybe because I deleted all Blender previews from small to large somewhere stored bit I cannot recall their location. I have to look it up.

Yes, so far orrect. You can build previews by choose one of the menues below append. However, it worked well on Sunday witout building and now I can reproduce the nice resulta from then. Instead of luxcore materials it renders blender engine only. I tried different approaches but all lead to simple previews. Very strange!

There is no possibility to exclude some material from Material override. It's make it hard for transparent and glass shader.

Yes, emission should be kept as well.
I'll have a look if I can implement exceptions without changing material export too much.

Is there any possibility to merge Luxcore shader node and volume as single Ui. so we don't need to double check everything all the time .

Something like that:

Or maybe it would be simpler, if a shortcut was introduced?
Like "Tab" is for Cycles node groups. "Tab" to get in & again "Tab" to get out of the group.

I have made it possible to add volume nodes to material node trees.
This makes it possible to have "inlined" volumes for simple cases where you only need the volume once in the scene.
I also added a new node tree preset called "Colored Glass" which adds a glass node and a clear volume node.
