I have just tried converting some textures from PNG to PVR. I have used the texturetool and the batch converter I found on the net to convert a texture, however I get an assertion error. I then loaded a pvr texture from the cocos2d test which worked.
I have also tried PVRTexTool which does work perfectly, however I have hundreds of textures and processing them one by one will be a pain.
I have followed all of the steps, but still cant get it to work.
What am I doing wrong?
