A fractal bitmap projected onto the object.
|Function||Add a bitmap to a material|
|Nearest C4D equivalent||Simple material has a link for a bitmap in most channels|
This node is used when you want to add a bitmap to a material. In the simplest case you specify the bitmap to use and link the Color output to the Color input of a node such as Diffuse BSDF.
Note that dragging a bitmap into the node editor window will automatically create an Image Texture node and add the bitmap to the node.
Please see the important note regarding bitmap images on the Known Issues page if you find that bitmaps applied to an object with this node are inverted on the Y axis.
Note: a * symbol next to the name indicates the parameter also has an input port. A # symbol indicates that the parameter can only be changed with an input node, not in the node itself.
Shows the currently selected bitmap, or black if none is selected. You can choose a bitmap by using the Texture link in the right-hand pane of the node editor.
This setting is only seen in the Node Settings pane. It is here you can choose a bitmap image or shader to load.
Load From Disk
If this switch is checked, Cycles 4D load the image from disk and will determine the image size from that. If it happens to get it wrong, choose Custom... from the Texture Size menu and enter the correct width and height in the custom width and height fields.
There is a limitation in that if you load a movie texture into this node, Load From Disk must be turned off. If it isn't, the movie will not load because the Cycles engine cannot load a complete movie, and instead samples the required frame from the movie as needed.
Texture Size drop-down menu
This menu contains a number of presets for common image sizes. This size is only used for the display of the image in the editor, it has no effect on the rendered result. If you have a high-resolution image you can choose a larger size, or select Custom... and enter the size into the Custom Width and Custom Height fields.
Custom Width and Custom Height
The image dimensions when Custom is chosen from the image size menu.
Color Space drop-down menu
This can be either Color Data or Non-Color Data. The difference here is that if Color is selected, Cycles 4D may perform colour space conversion on the output colour. Most of the time that is not required, so you can leave this as Non-Color Data. if the image map is a bump or alpha map, this should certainly be left as Non-Color Data or the node may try to convert it into colour data, giving erroneous results.
Texture Interpolation drop-down menu
This menu selects how the image data will be interpolated over a large area. The default is linear, which is suitable for most purposes. Cubic gives smoother interpolation but is slower, and can only be used when rendering on the CPU.
Closest basically means no interpolation; textures will stay pixellated which can be a required feature.
In Smart mode Cycles selects internally to use either bilinear or bicubic interpolation.
Texture Projection drop-down menu
This lets you choose from four projection methods:
Uses the Vector setting to determine the projection of the image, so by default this equates to UVW projection.
Assumes the bitmap is on a sphere enclosing the object and projects the bitmap from the sphere.
Assumes the bitmap is on a box with 6 sides enclosing the object and projects the bitmap from those sides.
Maps the bitmap to the object as though it was a cylinder.
Texture Extension drop-down menu
This menu selects whether or not to tile the bitmap across the object. The options are:
Tile the bitmap across the object.
This will not tile the bitmap and instead will repeat the edge pixels of the bitmap to cover empty space.
This will not tile the bitmap and will convert empty pixels into black.
Box Projection Blend
If Box was selected from the projection drop-down menu, you may see hard edges where the bitmaps projected from the six sides meet each other. These edges can be smoothed by increasing this value.
Flip Y Axis
If this switch is checked, the texture will be inverted on the Y-axis. This can be used to correct the problem of inverted bitmaps, should that occur.
Note: this switch has no effect unless the 'Load From Disk' switch has been unchecked.
Check this switch if you are using an animated texture. The real-time preview window needs to update itself as the scene time changes but there is no way to determine automatically if a texture is animated, so this switch must be checked manually to instruct the preview to update itself with each frame.
Important: when using an animated texture you must also untick 'Load From Disk' for the animation to work. See the 'Load From Disk' switch for more details. This is not necessary with an animated shader such as a Cinema 4D Noise shader.
This sets the coordinate system to use for the bitmap. By default this uses UVW mapping.

The output consists of alpha values.
