Tint only one texture and add it onto other textures

[Ricardo Teixeira]

Happy to hear it!

The limit depends on the shader model used, and a couple of Unity specific uses meaning that the actual sampler limit varies depending on your project.

I recommend looking into the Single channel sample, you can store multiple masks in a single channel using different gray values.

Hope it helps!

I can't seem to find the single channel sample. Does it have another name?
