I've this problem were I need to scale texture (B) to the same scale as texture A. All meshes are 256x256 with a texture of 1024x1024. For texture (A) I have set the texture coorinate node to tile 2x. This gives me right scaling size. But I can't do this with texture (B), because it will tile twice when adding a scaler…
Could you run that by me again? Edit: By the looks of it, you'll needing to be making your (B) texture just the curb on it's own and add it as a smaller mesh at the edges of your road as an end-piece.
