Physics Cloud Renderer is a renderer that can draw clouds close to physical behavior. Suitable for operation in linear color space or UniversalRP / HDRP environment.
Create Physics Cloud Renderer
To create a new Physics Cloud Renderer, select Assets->Create->Mewlist->MassiveClouds->Physics Cloud Renderer from the main menu or the context menu of the project view.
Lighting
Cloud Intensity
Cloud Intensity Adjustment(Controlled from AtmosPad)- Fine-tune the lighting for clouds
Sun Lighting
Auto Mode
Reflects the Directional Light setting of the scene.
Manual Mode
Rotation- Direction of the sun
Intensity- Sun brightness
Color- Sunlight color
Moon Lighting
Auto mode
Lets the Transform of a particular object in the scene be the light direction of the moon.
Intensity- Moon brightness
Color- Moonlight color
Manual mode
Rotation- Direction of the moon
Intensity- Moon brightness
Color- Moonlight color
Ambient Lighting
Auto mode
The color specified in the AmbientProbe or RenderSettings of the scene is treated as ambient light.
Pivot- Adjust how the ambient light hits the clouds.
Luminance Fix- Adjust the brightness of the ambient light.
Manual mode
Pivot- Adjust how the ambient light hits the clouds.
Luminance Fix- Adjust the brightness of the ambient light.
Sky Color(Controlled from AtmosPad)- Upward ambient light.
Equator Color(Controlled from AtmosPad)- Horizontal ambient light.
Ground Color(Controlled from AtmosPad)- Downward ambient light.
Sky
Enabled- Draw a built-in skybox.
Sky Exposure- Brightness of the sky.
Ground Color- The color of light reflected from the surface of the earth.
Saturation- Skybox saturation.
Atmosphere Thickness- Atmospheric thickness.
Gradation- Emphasis of light in the direction of the sun.
HDRI
Texture- Specifies the Cubemap to draw in Skybox. If not specified, nothing will be drawn.
Exposure- Adjusts the brightness of the HDRI.
Mix- Specifies the ratio of combining procedural skybox and HDRI.
Cloud
Layer
There are two layers for drawing clouds.
Main Cloud- This is the main cloud layer. Affects the drawing of shaft effects, god-ray effects and shadows.
Layered Cloud- This layer is for drawing the upper clouds. Does not affect shaft effect, shadows or god-ray effects.
Lighting settings
Profile(Controlled from AtmosPad)- Apply clouds to the layer by specifying a
cloud profile.
- Apply clouds to the layer by specifying a
Density Adjustment(Controlled from AtmosPad)- Cloud density.
Scattering(Controlled from AtmosPad)- Cloud scattering intensity.
- Check to override the setting value of
Cloud Profile.
Shading(Controlled from AtmosPad)- Cloud shadow adjustment. The smaller the value, the more the outline is emphasized, and the larger the value, the more the shadow against the light source is emphasized.
- Check to override the setting value of
Cloud Profile.
Shading Distance(Controlled from AtmosPad)- Cloud shade intensity.
- Check to override the setting value of
Cloud Profile.
Animation settings
Scroll Velocity- Scroll speed.
Phase- Phase of detail element.
Quality settings
Resolution- Cloud layer resolution scale for screen resolution.
Atmosphere
Atmospheric Scattering
Atmosphere(Controlled from AtmosPad)- Atmospheric scattering intensity.
Shadow(Controlled from AtmosPad)- The intensity of the shadow cast by the clouds on the Main Layer.
Sun Shaft(Controlled from AtmosPad)- Lens shaft strength against sunlight.
Coloring
Atmosphere Coloring(Controlled from AtmosPad)- Atmospheric scattered light coloring intensity. The larger this value is, the more the color changes to Atmosphere Color.
Atmosphere Color(Controlled from AtmosPad)- Correction color for atmospheric scattered light.
Atmosphere High Light Coloring(Controlled from AtmosPad)- Color intensity of scattered light in the direction of the light source. The larger this value, the more the color changes to the color specified by Atmosphere High Light Color.
Atmosphere High Light Color(Controlled from AtmosPad)- Corrected color of atmospheric scattered light toward the light source.
Cloud Interaction
Cloud Occlusion(Controlled from AtmosPad)- Shielding strength of atmospheric scattered light by clouds.
Cloud Atmospheric(Controlled from AtmosPad)- The degree of influence of atmospheric scattered light on clouds.
God Ray
God Ray(Controlled from AtmosPad)- Strength of Godley effect.
God Ray Start Distance(Controlled from AtmosPad)- The starting distance of the Godley effect.
Quality
Shaft Quality- Sun Shaft calculation accuracy.
God Ray Quality- Calculation accuracy of Godley effect. Please specify a large value for Godray because it is easy for noise to ride.
Resolution- Drawing resolution scale for atmospheric scattering effects on screen resolution.
Screen Blending- Switch between additive composition and screen composition. Used to suppress overexposure in the rendered result.
Fog
Shape
Ground Height(Controlled from AtmosPad)- The height to start the fog fade.
Range(Controlled from AtmosPad)- Height fog fade distance.
Density(Controlled from AtmosPad)- Fog depth.
Coloring
Coloring(Controlled from AtmosPad)- The color of fog is automatically determined by the ambient light, but the larger this value, the more the color changes to the color specified in Color.
Color(Controlled from AtmosPad)- Fog color.
Scattering(Controlled from AtmosPad)- Fog scattering intensity.
Advanced
Buffer Format- Render texture color format used by the renderer. The accuracy increases in the order of RGBA32 -> RGBAHalf -> RGBAFloat, but the memory used also increases. The higher the accuracy, the less likely Mach band will occur.
Sun Intensity Scale- Scale and adjust the intensity of sunlight.
Progressive- The larger the value, the more the Atmosphere drawing will be distributed over multiple frames.
Adaptive Sampling- When rendering Atmosphere, remove artifacts in areas with large Depth change.
Unity Qualities- Scales the render texture resolution according to the Unity Quality Settings value.
Forcing Full Quality- Render with the highest quality settings. It will be very expensive. If you check it during video rendering, you can get high quality rendering results.
