How to generate custom textures

Easy but manual way

• launch PVRTexTool (download link)
• open your image source file (png, jpg, tga, whatever)
• Edit menu > Encode
• Tweak settings, example :
  • Group/API = OpenGL ES 1
  • highlight selection = ETC1
  • ETC Encoding Mode = Fast
  • Generate MIPMaps checked
  • Vertical Flip checked
• Save your file as .ktx

Batch way…

…but-I-don’t-know-yet-how-to-customize-it is to use .bat files from babylonJS doc.

TimvanScherpenzeel let me know that he made a tool to make easier texture compression, for all platforms: Texture compressor.
