My God, i have just tested the profile. Now i understand why you ask for color replace feature in tex editor: you keep the huge but repetitive texture that auto created by software. That's unfortunately a massive unnecessary work. All you have to do is recreate the pattern with a few distinctive tiles (normally the texture will be 2x2 tiles only).
How to achieve it?
- In Texture Editor tab switch Mode from Shape to Tile
- Select or Shift Select the tiles you need (normally tiles that forms a square) then press Create
- Done. If the same pattern with huge texture already existed, it will be deleted and replaced with a new one with a tiny, compact texture.
- And you should edit the texture or clone pattern from there
