Making colour master....

[affixxius]

Hi,

Im wondering if anyone might be able to suggest a way for me to best control some colours.

I will have a scene with lots of items of clothes, toon shaded (very simpley). The clothes have various designs and details, but are generally limited to 3 colours. I am taking the designs from illustrator and making a 3 colour (RGB) matte in PS, then splitting this in octane to use a masks in layers.

I will need to make this scene multiple times with different colours, Im wondering if there is a way to set something up as a 'master' so i can access these colours from many materials, in one place and make a simple change?

I have tried Xpresso, but it seem very time consuming to link octane nodes to it! And also tried making a master material, with a load of RGB nodes , and then opened two mats in editor to link them, but again, it doesnt seem like a great option and also changes arent update in LV.

All ideas welcome

Cheers!
