d9dbff18a2 Add catch for when shadows are enabled between the update and draw traversals. 2011-10-03 15:57:06 +00:00

e8e25e82a9 From Jean-Sebastien Guay, changed the border colour for the shadow map to be 1 rather the 0 used for debugging so that areas outside the shadow map default to being unshadowed rather than shadowed. 
changed the shadow map texture assigment to StateSet so that it doesn't use OVERRIDE, enabling subgraphs to use the same texture unit for other textures if they so required.
                          tidied up indentation.

3a79bc343d Moved ViewDependetShadowMap parameter settings into a dedicated ShadowSettings object in prep for making it possible to scale the API to handle multiple lights and multiple shadow maps per light. 2011-09-07 15:55:54 +00:00
