Converted to basis format.


Code to convert caustic textures
---------------------------------
In TiffDecoder.cpp (in indigo):

for(int i=0; i<32; ++i)
{
	Reference<Map2D> im = decode("C:\\Users\\nick\\Downloads\\caus3 (1)\\save." + ::leftPad(toString(1 + i), '0', 2) + ".tif");

	PNGDecoder::write(*im.downcast<ImageMapUInt8>(), "C:\\Users\\nick\\Downloads\\caus3 (1)\\save." + ::leftPad(toString(1 + i), '0', 2) + ".png");
}



See substrata\gui_client\ResourceProcessing.cpp / .h to convert from .png to .basis.
