It would be relatively easy to create a "material from file node", it can be done with beginner-level python skills.
If you want to implement this, feel free to ask me for a more detailed explanation on how to do this.
But since this is a very niche request I won't implement it myself (I doubt many people want to write their materials this way).

What this node would do:
- read text file from disk into string
- replace the material name in this string with the correct one for the node
- create a pyluxcore Properties object from the string and return it (this is a finished material definition)

Over the last month, due to the lack of a Bevell shader, I had to work at Cycles in 8 projects.

Add sliders like add-on gaffer for Cycles so that I can select my HDRis with a mouse click, instead of crawling to folders each time and select them one by one.

Took more than one year but nearly all most requested features where implemented.

I looked at your website and I can understand why.. I am in the same boat. I'm a product designer and I do a lot of rendering of complex engineering parts, complex glassware (think glasses with complex extrudes that are impossible to fillet in Solidworks..
I can honestly say that unfortunately I have to dismiss using LuxCoreRender for a majority of my projects, just because of this feature.
I come from Keyshot, which has a rounded corners feature.. then I found out Cycles has support for this as well, but I would love to be able to use Lux because of its beautiful caustics. Cycles simply can't compete for that.

Is there any chance of this feature being implemented?
