Textures

Normal maps, height to normal, ORM packing, tiling check.

What it does

Four small jobs on 3D textures, on your device (nothing is sent).

Normal map: switches a normal map between OpenGL (Blender, Unity, glTF, green up) and DirectX (Unreal, 3ds Max, green down) by inverting the green channel. The same button goes both ways.
Height: makes a normal map from a height (or bump) map. Strength sets how deep the relief looks. The edges wrap around, so a tileable height map gives a tileable normal map.
ORM: packs three grayscale maps into one PNG, red = ambient occlusion, green = roughness, blue = metallic (glTF and Unreal convention). A missing map is replaced by a fixed value.
Tiling: shows the texture repeated 3 × 3 to spot seams. Shift by half brings the edges to the middle, to retouch them; that version can be exported.
The pixels are read as they are, without color conversion. 16-bit PNGs are read in 8 bits.
