The ProEXR package from the fnord software website also includes the ProEXR Comp Creator plug-in. The sample OpenEXR_channel_map.txt file available from the fnord software website includes documentation describing its use. #AFTER EFFECTS PARTICLE PLAYGROUND SMOKE DOWNLOAD#If this file is in the same folder as the OpenEXR format plug-in, the OpenEXR plug-in will use the information in this file to tag channels when it imports an OpenEXR file.Īn OpenEXR_channel_map.txt file is not included with After Effects, but you can download one as part of the ProEXR package from the fnord software website. To map channel names to the values of a specific type for use by other effects, you can use a file with the name OpenEXR_channel_map.txt. The R, G, B, and A channels are reserved to represent red, green, blue, and alpha values, but other channels can be used for any other characteristics. Unlike some other formats, like RPF, in which a specific set of channels is defined to always represent specific properties of a scene, the OpenEXR format is an arbitrary collection of channels with no inherent meaning. If you convert a layer with a 3D Channel effect to 3D and view the layer from anywhere but the front and center, it doesn’t appear as expected.ģD Channel effects can use the channels in OpenEXR files-such as a depth channel-if the channels have been tagged. You can layer 3D elements along the z-axis, insert other elements in a 3D scene, blur areas in a 3D scene, isolate 3D elements, apply a foggy effect with depth, and extract 3D channel information for use as parameters in other effects. The 3D Channel effects don’t affect other types of files.ģD Channel effects read and manipulate the additional channels of information, including z-depth, surface normals, object ID, texture coordinates, background color, unclamped RGB, and material ID. You don’t import ZPIC and EIZ files, but as long as they’re in the same folder with the PIC and EI files, you have access to their 3D channels using the 3D Channel effects. For PIC and EI files, the 3D channel information is in the ZPIC and EIZ files, respectively. You can import 3D image files saved in RLA, RPF, Softimage PIC/ZPIC, and Electric Image EI/EIZ formats. Use 3D Channel effects to integrate 3D scenes into 2D composites and to modify those 3D scenes. The sources of these 2D layers are image sequences that represent 3D scenes that have been rendered out of a 3D application. The 3D Channel effects work on 2D layers-specifically, 2D layers with 3D information in auxiliary channels. #AFTER EFFECTS PARTICLE PLAYGROUND SMOKE DRIVER#
