I am getting this error when using more than 4 textures: Shader error in 'Visor2.0/PlaneWater': Too many texture interpolators would be used for ForwardBase pass (11 out of max 10) at line 99
And here are the way I have the nodes connected:
And when I disconnect the multiply node that comes from the 'Texture 0' it gets good again.
I'm using Unity 2017.1.0p3

Please help :/

Hello joseguepardo, thank you for getting in touch!

What shader model are you using in your shader?

The interpolator limit is influenced both by the surface shader type and the shader model, so it might be using generating additional internal interpolators.

The only only way go around this limitation without reducing the amount of texture samplers is by using an higher shader model, or combining your textures into an array, thus reducing the amount of samplers.

Looking forward to your reply!
