I recently found UE4 rendering result differs from designer.

I would like to report this as I could reproduce this in a very simple material.

In the following comparison, left hand side from Designer looks just fine, while right hand side's UE4 texture result looks lot low-res, despite their resolution are both 2k.

I suspect this comes from pixel processor.

In the attached sbs graph, I made gradients and used their value as x and y input of sampler1 (this allows optimizing transformation in very complex graph).

I would like to know if this is just by design(part of optimization) or whatnot.

Thank you in advance!
