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.
