A finished render is often only the starting point for presentation. Before an image is shared with a client, submitted for review, or added to a presentation set, it may need a final round of cropping, color correction, or styling.
Post Processing in Lumion Cloud brings those refinements into the same workflow where images are already being reviewed and shared. You can crop and recompose an image, make visual adjustments, apply presets or LUTs, and save the result as a new Version or Variation without returning to Lumion Pro or using separate image editing software.
This is particularly useful during review. If feedback calls for a tighter composition, a warmer image, stronger contrast, or a different visual treatment, you can create and compare those alternatives while keeping them connected to the existing Project.
Knowledge Base Tip: Use Variations to explore different presentation treatments while keeping them connected to the same active Version.

2. Cropping and recomposing the image
6. Previewing and saving your changes
1. Opening Post Processing
1.1. Open the image you want to refine in Lumion Cloud.
1.2. Select the small Edit button immediately to the right of AI Edits.
The Post Processing workspace is divided into three main areas:
- Crop: crop, resize, rotate, flip, and straighten the image.
- Adjust: apply presets or refine the image using individual adjustment controls.
- Filters: apply Lumion LUTs or import your own LUT for a consistent presentation style.
2. Cropping and recomposing the image
2.1. Select the Crop tab.
2.2. Set the required output Size. Use the lock control if you want to preserve the current proportions while resizing.
2.3. Under Aspect ratio, select Free, Original, or one of the available preset ratios.
2.4. Use the Rotate & flip controls to rotate the image left or right, or flip it horizontally or vertically.
2.5. Use Straighten to correct a tilted horizon or refine the composition.
Knowledge Base Tip: Small composition changes can often resolve review feedback without requiring a new render.
2.2. When to use Crop
Cropping is useful when the render itself is suitable but the framing needs refinement.
For example, you can use Crop to:
- Remove unnecessary space around the main subject.
- Place more emphasis on a particular part of the design.
- Adapt an image to a different presentation format.
- Correct a slightly tilted horizon.
- Create alternative compositions from the same render.
This can be especially useful when responding to review comments. A change to the presentation may be possible without changing the original camera position or creating another render.
3. Adjusting the image
3.1. Select the Adjust tab.
3.2. Choose a starting point:
- Lumion presets: apply one of the ready made Lumion looks.
- Your presets: reuse adjustment presets you have saved for consistent styling across future images and Projects.
3.3. Refine the result using the individual adjustment controls.
Brightness: changes the overall lightness of the image.
Contrast: increases or reduces the difference between light and dark areas.
Saturation: controls the intensity of the colors.
Temperature: shifts the image toward a warmer or cooler color balance.
Tint: adjusts the balance between green and magenta.
Highlights: adjusts the brightest areas of the image.
Shadows: adjusts the darkest areas of the image.
Sharpness: increases or reduces the definition of edges and fine details.
Vignette: adds edge darkening to draw attention toward the center of the image.
When you create a look you want to reuse, save it as a custom preset so the same adjustment style can be applied consistently across other presentation images.
Knowledge Base Tip: Start with a Lumion preset, then use the sliders for smaller corrections. This is usually faster than building a look from the default settings.
4. Working with presets
Presets allow several adjustment settings to be applied together.
They provide a quick starting point for exploring different presentation treatments and can also help maintain a consistent appearance across several images.
4.1. Preset controls
4.1.1. In the Adjust tab, select Lumion presets.
4.1.2. Select a preset to apply it to the current image.
You can continue changing the individual adjustment controls after applying a preset.
4.1.3. Select Your presets to access presets you have previously saved.
4.2. When to use presets
-
Use Lumion presets when you want to quickly explore different visual treatments before refining individual settings.
-
Use Your presets when you have created a combination of adjustments that you want to reuse.
This is particularly useful when several images belong to the same presentation set. Instead of adjusting every view independently, you can establish a visual treatment on one representative image and use it as the starting point for the others.
Different renders may still require small individual corrections because their lighting and composition can vary.
Knowledge Base Tip: Establish the overall treatment on one representative image first. Save the settings as a preset, then use that preset as the starting point for the remaining views.
5. Applying filters and LUTs
The Filters tab provides Lumion LUTs and support for imported LUTs.
A LUT applies a predefined color transformation to the image and can be useful when several presentation images need to share a consistent visual style.
5.1. Filter controls
5.1.1. Select the Filters tab.
5.1.2. Under Lumion filters, select the filter you want to apply.
5.1.3. Use the Intensity slider to control how strongly the selected filter affects the image.
5.1.4. To use your own LUT, select Import LUT and choose the LUT file you want to use.
5.1.5. Imported LUTs are available under Your filters and can be reused on other images.
5.1.6. Select No filter to remove the active filter.
Lumion filters: provides the supplied Lumion LUTs.
Your filters: contains LUTs you have imported.
Import LUT: lets you add a custom LUT.
Intensity: controls the strength of the active LUT.
No filter: removes the active LUT treatment.
5.2. When to use filters and LUTs
Use a LUT when you want to apply a consistent overall color treatment rather than adjusting each color characteristic individually.
LUTs can help you:
- Give several images a consistent presentation style.
- Establish a warmer or cooler overall mood.
- Apply a familiar visual treatment across different Projects.
- Quickly compare different presentation directions.
The Intensity control is useful because a LUT does not always need to be applied at full strength. Reducing Intensity allows more of the original render to remain visible while still introducing the desired color treatment.
5.3. Using adjustments and LUTs together
The Adjust and Filters tools can be used together.
A preset or individual adjustment can establish the lighting and color balance of the image, while a LUT can provide the final color treatment.
When combining them, evaluate the final image rather than the strength of each individual setting. Strong adjustments combined with a strong LUT can produce an exaggerated result.
6. Previewing and saving your changes
Once the image has been refined, review the result before deciding how the edited image should be stored.
6.1. Reviewing the image
6.1.1. Compare the edited result with the original image.
Check:
- The composition.
- Overall brightness and contrast.
- Color balance.
- Bright and dark areas.
- The strength of any preset or LUT.
- Whether the edited image communicates the design more effectively.
This is particularly useful when responding to review feedback because you can evaluate whether the change addresses the original comment.
6.2. Saving the image
6.2.1. Select Save.
6.2.2. Choose how the edited image should be stored.
Save as New Version: creates a new Version containing the edited asset. The newly created Version becomes the active Version.
Save as New Variation: creates a new Variation under the current active Version.
6.2.3. Leave Continue editing selected if you want to remain in Post Processing after saving.
6.2.4. Select Confirm save.
6.3. When to use Versions and Variations
Use a new Variation when you are exploring alternatives.
Examples include:
- Different crops.
- Warmer and cooler treatments.
- Alternative presets.
- Different LUTs.
- Different levels of contrast or saturation.
Use a new Version when the edited image represents the next stage you want to continue reviewing or working from.
Keeping these alternatives inside the Project allows presentation refinements to remain connected to the same review workflow instead of creating separate files in external editing software.
Knowledge Base Tip: Use Variations while exploring presentation options. Create a new Version when the preferred treatment is ready to become the next stage of the image.
