Multi Shader

Basic Shader

Shader Properties

Mode

Use this setting to define which color values will be used in the allocation, or if the shaders should be allocated uniformly across all clones.

Index Ratio

The shaders will be allocated uniformly across all clones (e.g., for Radial and Linear clone modes, the following would be true: If 2 shaders are applied to 10 clones, the first 5 clones will be assigned the first shader, the last 5 the second shader. For other clone modes, the U-coordinate will be used for the orientation of the UVW-coordinate system). See Effectors) for more about the orientation of the UVW coordinate system.

Color Brightness

The clone’s grayscale value.

Color Red

A clone’s individual grayscale value.

Color Green

A clone’s individual grayscale value.

Color Blue

A clone’s individual grayscale value.

Average Color (Euclidean Color Distance)

Average Color (Hue Difference)

A mosaic of a glacier created from 1000 different helper images.

Both of these modes ascertain an average color value for each image that is loaded (this can take a moment or two when rendering, depending on the number of Shaders used). This color value will then be compared with the clone color by one of these modes. The Shader that is closest to this clone color will be used for that clone.

What’s this good for? This lets you use images (which should have as many different average color values as possible) to recreate a texture that is projected onto a collection of clones (see Channel). To keep a long story short: you can create your own mosaic image in which each clone represents a mosaic tile.

Average Color (Euclidean Color Distance) is the recommended setting because the colors will more closely represent the original colors. Average Color (Hue Difference) ignores brightness and saturation and will produce a more colorful result without details.

How to Create a Mosaic Image

Tip:
You can improve the quality of your mosaic images by increasing the size of the Blur Offset in the, source image’ (the glacier in the example above). This will subdue areas in which the Shader Effector had made out too many details, which will result in a more harmonious mosaic image.

Blend Color [0..100%]
Mode

Multiply is set to 100% a much more harmonious mosaic image will result.

These settings will only be made available if one of the Average modes is selected (the arrangement of the mosaic images will remain the same). In order to achieve good mosaic images you will need a great number of images with a wide variety of color variation among them. It can, however, be quite a task gathering the required number of images. Using the Blend Color and Mode, cheats’ can help in that they blend the mosaic images with the cloned colors from the Shader Effector.

Add

Click this button to add a new empty shader selection.

Clear

Pressing this button will delete all shaders. Two empty shader selection fields will remain (incl. all loaded shaders/textures).

To Layers

This button will be active if a video has been loaded into the shader. As soon as the button is clicked, each (!) frame of the video will be viewed as a separate shader. Make sure short videos are loaded. Otherwise your computer will be bogged down for quite a while …

A Multi Shader can contain several individual shaders that it can assign to clones using differing criteria.

This also works for image sequences (an image viewing application will rename the images accordingly). Load the first image of the sequence into the Multi Shader. Then click on either the image name or on the preview image to access the bitmap shader properties. Click on the Calculate button in the Animation tab. The bitmap shader now knows it is dealing with a sequence of images. Now switch back to the Multi Shader and click on the To Layers button.

Add from Folder

Use this command to select a folder from which Cinema 4D will import all bitmaps / videos contained in that folder (not including any files in existing sub-folders).

 Shaders

The Multi Shader can contain several individual Shaders, which can be assigned to Clones according to different criteria.

Active

Lets you activate or deactivate a Shader. If disabled, the given Shader will not be available to the Multi shader.

Remove

Deletes the selected Shader.

Up / Down

Moves the selected Shader one position up or down.
