MaterialEditor v1.9
🕑 Added 2019-11-11 03:54:52 +0000 UTCChangelog:
- Added Offset and Scale editing for textures
- Properties that have been edited will be marked by a *
- Added some missing properties for main_hair shaders (LineColor and ShadowColor)
- Fixed a typo in property names for clothes shaders in AI (Color1_2, Color2_2, Color3_2)
- Fixed data being lost on clothing color or pattern change
- Fixed data being lost on clothing when accessories are transferred between slots
- Support for replacing MainTex on clothing and skin
MainTex can now be replaced for clothing, similar to Clothing Overlays. Unlike clothing overlays, you must replace the texture in full, no partial overlays. Overlay textures are limited in resolution based on the clothing, however with MaterialEditor there is no texture resolution limitation allowing you to use extremely high quality textures.

In the image above, a 4096x4096 image is applied as an overlay (left) and as a MainTex replacement with MaterialEditor (right). The overlay is scaled down to 1024x1024 by the game and fine details are lost.
Note: Replacing the MainTex of clothing will override Overlays. Clothing overlays can safely be used with MainTex replacement without errors, but MaterialEditor changes will always take priority. Very high resolution textures can slow down card loading so use them responsibly. Stick with Overlays at the default resolution unless the higher resolution textures are necessary.
