Here's a quick test of the 'same texture from multiple directories' question: http://gnsfiles.250free.com/textureTest.zip
From the above test it -does- seem as if Blitz loads a new copy of the same texture if it's in a different directory. Varying texture flags will also load new copies of a texture.
