1. Lumion 2023 and newer

1.1: For Rasterization rendering

1 Star: Draft quality:

Everything on, no anti-aliasing.

2 Star: Good quality:

Everything on, 4x anti-aliasing. 

3 Star: Production quality:

Everything on, 8x anti-aliasing. 

4 Star: Production quality:

Everything on, 16x anti-aliasing.

1.2: Samples rendered for Ray Traced rendering

At the bottom of the rendering screen, Lumion shows two values.

Example:

Say for example you chose a Sample in the Ray Tracing Effect of 512.

1. The first number is the total Samples from the Ray Tracing Effect (example 512).  It increases from 0 to the number of Ray Tracing Effect - Samples.

2. The second number is the calculated maximum Samples for a render at the selected Output Quality you have chosen. 

For your 2 Star example: there are 4 samples AA, and the quality to render at ratio is 16/4 = 4.  The maximum number of samples to render is: 512/4 = 128.
  

Ray Tracing: 512 Samples, Output Quality Stars selected: 4 (16 AA) = 512 samples.

Ray Tracing: 512 Samples, Output Quality Stars selected: 3 (8 AA) = 256 samples.

Ray Tracing: 512 Samples, Output Quality Stars selected: 2 (4 AA) = 128 samples.

Ray Tracing: 512 Samples, Output Quality Stars selected: 1 (0 AA) = 1 sample.

When rendering with the Denoiser options then see this article, Section 2.4.3: Summary of Denoiser Options:

• Knowledge Base:  How do you use the new Ray Tracing Effect?

For 360 Panorama see the options when wanting to use the Denoiser:

2. Lumion 12:

1 Star: Draft quality:

Everything on, no anti-aliasing.

2 Star: Good quality:

Everything on, 4x anti-aliasing. 

3 Star: Production quality:

Everything on, 8x anti-aliasing. 

4 Star: Production quality:

Everything on, 16x anti-aliasing.

3. Lumion 8 to 11:

1 Star quality: Draft quality

Sky, sun, and clouds will remain static. Rendering with a Sun Effect or a Sun Study Effect requires 2 Star quality (or better) to animate the sun position. The following features and Effects will be rendered at draft quality:

• Anti-aliasing.
• Shadows.
• Depth of Field Effect.
• Motion Blur Effect.
• Global Illumination.
• Hyperlight Effect.
• Sky Light 2 Effect.
• Volume Clouds Effect.
• Leaves on trees/plants.
• Semi-transparent materials.

2 Star quality: Good quality

The following features and Effect will be rendered at draft quality:

• Anti-aliasing.
• Shadows.
• Depth of Field Effect.
• Motion Blur Effect.
• Global Illumination.
• Hyperlight Effect.
• Sky Light 2 Effect.
• Volume Clouds Effect.
• Leaves on trees/plants.
• Semi-transparent materials.

3 Star quality: Production quality with 4 sub-samples

The following features and Effects will be rendered with 4 sub-samples per frame:

• Anti-aliasing.
• Shadows.
• Depth of Field Effect.
• Motion Blur Effect.
• Global Illumination.
• Hyperlight Effect.
• Sky Light 2 Effect.
• Volume Clouds Effect.
• Leaves on trees/plants.
• Semi-transparent materials.

4 Star quality: Production quality with 8 sub-samples

The following features and Effects will be rendered with 8 sub-samples per frame:

• Anti-aliasing.
• Shadows.
• Depth of Field Effect.
• Motion Blur Effect.
• Global Illumination.
• Hyperlight Effect.
• Sky Light 2 Effect.
• Volume Clouds Effect.
• Leaves on trees/plants.
• Semi-transparent materials.

5 Star quality: Production quality with 16 sub-samples

The following features and Effects will be rendered with 16 sub-samples per frame:

• Anti-aliasing.
• Shadows.
• Depth of Field Effect.
• Motion Blur Effect.
• Global Illumination.
• Hyperlight Effect.
• Sky Light 2 Effect.
• Volume Clouds Effect.
• Leaves on trees/plants.
• Semi-transparent materials.

4. Lumion 7.5 and older:

The 5-star system that is described in section 2 also applies to Lumion 7.5 and older versions.

In addition, please note the following:

When rendering Movies, the clouds, moon, and stars are rendered at a lower quality setting by default, regardless of the Final output quality setting.

To set the sky to the best possible render quality when rendering Movies, please add a Cloud Effect and turn on HQ Clouds in movie render (slow). Please note that this will prolong the time it takes to render your Movie.

Note: Rendering in Panorama Mode was also subject to some further limitations, even at the highest Star Quality, of which Effects were possible for 360 rendering for versions up to V11.
