Hello all,
I’m having difficulty figuring out how to tile 4 textures separately using Customized UVs for mobile. First I am limited to 3 Custom UVs on ES2, and then I am limited to 3 texture coordinate sets in ES2, as stated in the error below:
Error [ES2] (Node TextureCoordinate) Only 3 texture coordinate sets can be used by this feature level, currently using 4.
Below is a screenshot of what I want, but I am unsure how to achieve this while still abiding by the above guidelines.** Is it even possible to accomplish the following on ES2 in a material using Custom UVs?**
I have a single RGB image consisting of 3 separate grayscale textures. Grass is on Red, Transition Mask is on Green, and Rock is on Blue. I want to tile the Grass texture** twice** [Grass Small (x100) and Grass Large (x10)], the Rock texture once (x20), and blend between the grass and rock using a painted white/black Transition Mask. The Mask doesn’t tile, so it needs texture coordinates equaling (x1).
I would also be interested to know the potential performance hits of tiling the channels of this single 1024 x 1024 image as many times as I have (x100, x10, x20) using Custom UVs on mobile.
Thank you so much for any advice you can offer on this.
