Surface pattern on blended polysurface

I’m new to grasshopper and I have a simple question about workflow for surface panelling for a blended surface…

I made a surface where I want it to be covered with a certain pattern, but it is now a polysurface with different uv densities throughout due to the blending process and so the panelling isn’t working very well when I try both morphing it onto the polysrf (converted into mesh) directly or doing it surface by surface

would like to know how to do it as one surface
