Rendering 9 Tiles

It’s very complex to manage 9 * n footages (background, occlusion.. etc.) and the load in compositing ‘s software could be very slow and tedious.

For to help compositors I have made a python class that make a xml with the maya scene’s features. This file will be read from a software compositing that it’ll load all footage in the right position.

<?xml version="1.0" ?>
<Project>
	<FileName durata="11.0" fps="25" name="scenePostMau" xRes="1920" yRes="1080"/>
	<Dir path="C:/Users/Maurizio/Documents/maya/projects/GroundTruth1/images/scenePostMau/"/>
	<Layer name="depthLayer"/>
	<Layer name="renderSetupLayer1"/>
	<Camera name="cam1_L"/>
	<Camera name="cam2_R"/>
	<Camera name="cam3_L"/>
	<Camera name="cam4_R"/>
	<Camera name="cam5_L"/>
	<Camera name="cam6_R"/>
	<Camera name="cam7_L"/>
	<Camera name="cam8_R"/>
	<Camera name="camera1"/>
</Project>

In my case we are working with After Effects, handling a bit of javascriptx the loading of all footages take few seconds.
