6.3 Interaction• alpha: Sets the state of alpha rendering.· true: renders alpha channel.· false: does not render alpha channel.• alpha RED/GREEN/BLUE: Sets the alpha color.• overwrite: Allows to overwrite an existing file with the same name.· true· false• alpha premultiply: Multiplies the alpha and the color channel in the resultingimage.· true· false• frame step: Defines the frame offset for the rendering of image sequences.Example: Step 3 renders only every third frame (0, 3, 6, 9, ...).• tonemap hdr: Applies tone mapping to the high dynamic image rendering.As a result, the 32 bit renderings look the same in the compositing tool asset in VRED. However, the values of the image will be compressed by thechosen tone mapper to values between 0 and 1. In doing so, the dynamicrange will be lost. Therefore, effects like glow will be hard to calculate inthe compositing tool afterwards.· true· false» createCubeImages: Exports an environment image.• node_name: Specify the name of the node that will be used for the cameraposition.• type: Defines the type, as which the cube image will be created. 6 imageswill be rendered and processed based on the chosen type.· 0 = separate images167
