Re: About shadows and emission

Hi, I'm starting to understand your issue. I'm also not able to reach a nice result within an accaptle time. Trying to reduce time leads to some issues with network rendering. I posted this into another thread. This is a mix of rough glass and architectural glass (350 samples) 1.jpg This is pure arc...

Network Render time out

Hi, I'm continuing testing network rendering. After running console and single node on a single machine this message appears in console: LuxCore 2.1beta2 NetBeaconReceiver thread started. Discovered new node: 192.168.188.23:18018 Discovered new node: 192.168.188.25:18018 Creating single image render...

Re: About shadows and emission

Hey,

Will your share your scene? Maybe we could try to improve settings...
Lux render glass material is one of the best regarding realism. It should be possible to make it look like the real thing.

Re: About shadows and emission

Hi,

What makes the bulb looking funny while using the filament as an emitter? Should be the most realistic option, shouldn't it?

Re: How to imitate real world materials

Hello, No, my intension is to directly control each of the elements. All elements in transmission should handle transitive properties only, etc. I thought that settings like diffuse colour = black means that I reduced the reflected amount of light in glossy translucent tab down to 0. In case of atta...

Re: How to imitate real world materials

Hi, I've updated my real world material node. Now there is a reflection, transmission and absorption portion available. Each, the reflective and transmittive portion, could be separated into lambertian, gaussian and specular elements. Node_ext.jpg While testing the node setup an strange behaviour co...

Re: How to imitate real world materials

Hi, Not yet. This my first test for working with values. Those numbers came more or less free from mind. Let's assume I've a real sample in front of me. How would you test whether is representation in luxcorerender is right? I can't reproduce the lighting conditions of my appartment easily (quickly)...

Re: How to imitate real world materials

I dont't get it. I thought this is the logic: Section 1 Mixed with 0.5 factor (so 50% M1 and 50% M2) M1 Glossy with 0.1 roughness (Color 0 (black) Diffuse and 1 (white) for specular color) M2 Mirrot (Color 1 (white)) Section 2 Mixed with 0.2 factor (so 20% M1 and 80% M2) M1 Matte material (Color 1 (...

How to imitate real world materials

Hello all, I'm a bit lost while trying to create a specific material. There are lots of numbers in node tree and I don't know what they are exactly doing. This is an very simple example, maybe someone could help me to create the first node tree for that. From light measurements I know that the surfa...
