I have an issue about using render layers
when I use render layers sometime I can't remove selected object in one layer or add or assign other shader....
for example I have 2layers 'A' layer is 'master', 'B' layer is 'matte' so I try delete one object from 'B' layer. using 'remove selected objects'. but it doen't work.....even assign some other matrials.
yep.. I think it's a Maya bug.. wich maya are you using? 2010?
In Maya 2010 (maybe they still happen in 2011 and 2012) there were some problems regarding the render layers that when switching layers some errors may happen in matieral assignments and overrides.. this is the MEL to correct it:
I dont have a clue if this MEL will help with your particular problem... but try it and let us know
Just open you scene, execute this MEL and then try to mess around with your layers to see if anything happened!
