Would this be possible? Id like to have two layers in Photoshop,each with their own color information along with a mask. What id like to know is if there is a way to link the 2 masks. So for instance if i use the smudge tool or paint on the mask on the top layer,the mask on the layer below will also be affected.
Fonfa had it, if you want one mask to edit two separate layers, you group them and apply the mask to the group and disable the two masks on the layers. Awesomeness.
I don't understand why you want the two masks to be linked together. Can you give a practical example of what you would use this for? I can only assume that you're talking about painting a mask on say the diffuse and specular at the same time? For those sorts of cross-grouping mask links I just copy/paste from one to the…
I don't know if that's what you want, but you could include those two layers inside a layer group that has its' own mask besides their individual ones.
You can put two layers in a folder and then put a mask on the folder. This will mask both layers with the same mask. You can even have masks on the layers in the folder as well. Is that what you're asking about?
