Cloud Paint — User Documentation

• Blender 4.5 or above (including Blender 5.x)
• Eevee only — Cloud Paint is designed for Eevee / Eevee Next. Cycles is not supported.
• Recommended for anime scenes, fantasy skies, toon environments, and stylized environment workflows.

Open Blender, go to Edit > Preferences > Add-ons

Click the Install... button and select the Cloud Paint .zip file

Enable the add-on by checking its checkbox in the list

The Cloud Paint panel has two main sections:

• Assets Library — Browse cloud assets and generator presets, then import or apply them
• Control Panel — Adjust Geometry Nodes modifier parameters on the active object

Use the header icon to Reload Assets (refresh thumbnail library).

• Library Type: Filter by category, or choose All to show every asset
• Thumbnail Grid: Click a thumbnail to select an asset or generator preset
• Regular assets show Import Asset; generator presets show Cloud Generator

Steps

1. In Assets Library, choose a Library Type (or All)
2. Click a cloud asset thumbnail (non-generator item)
3. Optionally enable Import at 3D Cursor to place the cloud at the cursor; otherwise it imports at the world origin
4. Click Import Asset

The Cloud Generator converts a mesh object into a painterly stylized cloud by applying a Geometry Nodes modifier. The library includes 10 ready-to-use generator presets for different cloud styles.

• Generator items appear under library types ending with _Generator
• Select one or more mesh objects, pick a generator preset, then click Cloud Generator
• If the active object already has the generator modifier, the button turns red and removes it from selected objects

Steps to Apply a Generator Preset

1. Select a mesh object (plane, cube, or custom silhouette)
2. In Assets Library, filter to a _Generator category
3. Click a generator preset thumbnail
4. Click Cloud Generator to apply the modifier
5. Open Control Panel to fine-tune shape, density, and look

Common issue: mesh too small

When generating a cloud with Cloud Generator, if the mesh object is too small, the result may not look correct. Scale up the object first, then apply Scale & Rotation (Object > Apply > Scale & Rotation, or press Ctrl+A and choose Scale & Rotation).

The Control Panel displays Geometry Nodes modifiers on the active object and lets you adjust parameters without opening the modifier stack.

• Modifier Expand/Collapse: Click a modifier name to show or hide its parameters
• Category Groups: Related settings are grouped into collapsible categories for easier navigation
• Supports sliders, vectors, colors, materials, collections, and object inputs where exposed by the node group

Select an object with a Cloud Generator modifier applied, then expand categories in the Control Panel to shape your cloud and art-direct the final look.

Cloud Paint is built for Eevee. If your scene is not set up correctly, a red warning appears at the top of the panel.

Click Click to Fix Eevee Settings to switch to the correct Eevee engine and enable ray tracing when needed.

Quick sky with built-in assets

1. Fix Eevee settings if prompted
2. Browse Assets Library and import ready-made clouds
3. Move, scale, and duplicate clouds to block out your sky

Custom cloud shapes from mesh

1. Create or select a mesh that defines your cloud silhouette
2. Pick a _Generator preset and click Cloud Generator
3. Tweak parameters in Control Panel until the shape and painterly look match your scene
4. Try different presets to compare styles without rebuilding the mesh

• Cloud Paint supports Blender 4.5+ and is designed for Eevee only. Cycles is not supported.
• Clouds generated from larger or denser meshes may produce higher polygon counts and can affect performance on lower-end hardware.
• Performance depends on your hardware, scene complexity, and viewport settings.
• This product is intended for use inside Blender. Exporting Cloud Paint assets, shaders, or node systems to other software or game engines is not officially supported.
