1. Default Glass:

In the initial release of Lumion 2023, the Glass Material is not yet implemented in the Ray Tracing pipeline.  Lumion combines the Ray Tracing process to include the Glass Material rendered with the latest from the Rasterization pipeline. 

However, Glass-like surfaces can be easily created to work nicely with the Ray Tracing Effect by creating suitable materials.

2. Glass for a Ray Trace Render:

2.1: To create a Glass-like surface that can be used in Ray Tracing, please use the following settings for the Standard Material:

2.2: Settings:

• Texture: 0%
• Map Scale: 0%
• Relief: 0%
• Roughness: 0%
• Reflectivity: 200%
• Metalness: 100% 
• Emissive strength: 0%
• Displacement: 0%
• Opacity: 20-30%
• Subsurface Scattering: 0%
• Clearcoat: 0%
• Flicker Reduction: 0%

You can vary these settings depending on the strength of reflection needed and absorbency of light needed using darker colors:

• Reflectivity: 5 to 200%
• Metalness: 150 to 200% - has the most impact on strength
