Please give me sincere advice …
Try using Texture Coordinate in material editor
Hard to see what’s written there, the screenshot is low resolution.
Could be, but the question could be interpreted as inverting, as this is much more common once you’ve already mapped a texture to a mesh (texture screenshot looks like a UV), and want the “low” to become “high” on normals.
Both are best done by altering the source file so that source and UAsset don’t mismatch in data. @erckmay63 ?
