Native perspective and orthographic (Left, Right, Front, Back, Top, Bottom projection) Cinema 4D cameras are supported by C4DtoA. The supported settings of a Camera object are:
To adjust the settings for an Arnold camera node, you need to add an Arnold Tag to the camera object. To do this, you must right-click the Camera and select C4DtoA Tags > Arnold Parameters:
The following parameters are common for each camera type. For a specific type of parameters, please see the specific camera pages.
A video tutorial about Rolling Shutter can be found here.
The Focus distance attribute is on the standard C4D camera parameters (Object tab).
Select how camera aperture size is calculated:
By default, the shutter size defined in the Arnold Render settings is used. This option allows you to set up a smaller shutter size within the global range.
The native Stereoscopic camera effect is supported by C4DtoA, however, the Arnold drivers do not support writing anaglyph images, they can only output the image from the left and right camera. To specify the path in an Arnold driver you can use the following tokens:
If no token is defined in the path, the 'left' or 'right' postfix is added to the file name (e.g. myimage_left.exr).
The IPR displays the red-cyan anaglyph image when the Stereoscopic effect is enabled.
Only the red-cyan anaglyph image is supported in the IPR, the different modes and anaglyph settings of the Stereoscopic effect from the render settings are not supported.
The IPR window also offers to select from the anaglyph, left or right camera to display.
You can define custom Arnold camera types via the Arnold tag of a Camera object. Enable Custom type and select the Camera type on the Camera tab of the tag. In this case, the native C4D Camera Projection type will not be used.
Arnold provides the following built-in camera types:
The perspective or standard camera is the most common. Both the perspective and fish-eye cameras provide a depth of field and model the effect of altering the camera aperture. The orthographic, cylindrical and spherical camera types enable certain non-perspective views to be created but do not attempt to model any real-world lens effects (they are normally used for creating environment maps).
Developers can extend Arnold with custom camera implementations. To install a third-party camera, you must point the ARNOLD_PLUGIN_PATH environment variable to the folder where the camera plugin binary is located, or just simply copy the binary to the C4DtoA/shaders folder. The camera can then be selected in the Custom camera type combo box like any other built-in camera.
