pymel.core.rendering.iprEngine¶
- iprEngine(*args, **kwargs)¶
Command to create or edit an iprEngine. A iprEngine is an object that watches for changes to shading networks and automatically reshades to generate an up-to-date image.
Flags:
Long Name / Short Name Argument Types Properties copy / cp unicode Copies the deep raster file, as well as its related files, to the new location. defineTemplate / dt unicode Puts the command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template. diagnostics / dig bool estimatedMemory / mem bool Displays the estimated memory being used by IPR. exists / ex bool Returns whether the specified object exists or not. Other flags are ignored. iprImage / ipr unicode Specify the ipr image to use. motionVectorFile / mvf bool Returns the name of the motion vector file used by IPR. object / obj PyNode The objects to be tuned. region / r int, int, int, int The coordinates of the region to be tuned. The integers are in the sequence left bottom right topor x1,y2 x2,y2 relatedFiles / rel bool Returns the names for the related files, e.g, the non-glow-non-blur image, the motion vector file, and the depth-map files. releaseIprImage / rii bool The ipr image should be released and memory should be freed. resolution / res bool The width and height of the ipr file. scanlineIncrement / sli unicode Set the scanline increment percentage. If the height of the region being update is 240 pixels, and the scanlineIncrement is 10% then the image will refresh blocks of 24 scanlines. showProgressBar / spb bool Show progress bar during tuning. startTuning / st bool An ipr image has been specified and now changes to shading networks should force an image to be produced. stopTuning / spt bool Tuning should cease but ipr image should not be closed. underPixel / un int, int Get list of objects under the pixel sprcified. update / u bool Force an update. updateDepthOfField / udf bool Force a refresh of depth-of-field. updateLightGlow / ulg bool Automatically update when light glow changes. updateMotionBlur / umb bool Automatically update when 2.5D motion blur changes. updatePort / up unicode The name of the port that is to be updated when pixel values are recomputed. (not currently supported) updateShaderGlow / usg bool Automatically update when shader glow changes. updateShading / us bool Automatically update shading. updateShadowMaps / usm bool Force the shadow maps to be generated and an update to occur. useTemplate / ut unicode Force the command to use a command template other than the current one. Flag can have multiple arguments, passed either as a tuple or a list. Derived from mel command maya.cmds.iprEngine
Example:
import pymel.core as pm # Create a iprEngine and tell it about an already created ipr image. pm.iprEngine(ipr='iprImages/persp_scene1_ipr.iff') # Tell the iprEngine about the region to update. pm.iprEngine( 'iprEngine1', e=True, region=(10, 10, 100, 100)) # Tell the iprEngine to watch changes and update pixels. pm.iprEngine( 'iprEngine1', e=True, startTuning=True )
