I found a setup for a tri-planar shader online and it gives good results for me so I quite like it. But every time I want to swap the texture I have to swap it for each of the texture nodes. That feels like it is unnecessary trouble so I was wondering if there is a way to simplify it so that I can easily swap them. Something like instancing the texture nodes to inherit the texture swap.
The same problem applies to the "Mapping" nodes only that there I have a free slot for scale on each node so I think I can just control each of them simultaneously with one node that gives a constant value.
Thanks for your help!
