i’ve searched the archives for this but drew a blank - i only know the basic MEL commands to control shader attributes individually, not all together. selecting a bunch of shaders and changing the values in the channel box doesn’t work because that will only change shaders of 1 type (blinn or lambert etc, whichever is selected last i think). and that also doesn’t work with non-keyable attributes.
basically i want to control the “miIrradianceColor” attribute on all materials in the scene. the problem is by default its a non-keyable attrbute, so i need MEL to first unlock it and then set the RGB values.
its pretty lame that maya hasn’t had some sort of global shader control gui built-in since version 1… it would be such a useful feature.
any help on this would be greatly appreciated.
