Re: Warframe Online .png textures

That seems to work just fine (for an assumed DXT1 DDS file). How did you find that sizeBlock = 0x2000 ? As you know DDS format have simple format and when I just put standard DXT1 header on the file (png thing), I can recognize rough view of the image. and I found some binary density pattern and it...

Re: Warframe Online .png textures

Could you post your code for reversing the these png's? My experimental converter is quite primitive and it's really complicated to use. So here is the actual algorithm in psuedo-code. fileSource = blah.png fileDestination = blah.dds.raw bufBlockBuffer_0 [] bufBlockBuffer_1 [] sizeBlock = 0x2000 po...

My converter is almost done but still not perfect. anyway, every non-ASCII files used by EE are headerless. (e.g. wav files are headerless xwm) If anyone knows get proper header inf...
