UE-21632

UV Coordinates and Gradients are behaving unexpectedly when run 1-0 (White on Top, Black on Bottom)

UV Coordinates and Gradients are behaving unexpectedly when run 1-0 (White on Top, Black on Bottom)

Developer Notes

Not a bug. the input UV float(u,v) becomes transformed to float2(u*v,v*v) because the multiply in the end goes to u and v
so both u and v gets distorted.
you can use component mask and get this: float(u*v, v)

Description
