DDS compressed texture support?

Post by arangel »

Could Blender support any kind of hardware texture compression, like .DDS?
Is DDS just for DirectX or OpenGL too? Is there any kind of texture compression for OpenGL?
DDS is great because it reduce (up to 10 itmes) the size of a texture and it stays compressed in the graphic card video memory, allowing more textures to be displayed by the game engine.

There are plguins from nVIDIA and other companies to make MAX and LightWave able to read .DDS

not all dds compressions are supported by all graphic cards

I don't belive opengl [the standards] support it, but there are probably extensions for it

opengl does however support pallatized images, but blender doesn't exploit this either [it will send opengl a rgb or rgba image]

DXTC compression would be nice too

uses 4x4 tiles, a high value and a low colour value, then for each pixel it can be one of 4 variants inbetween.

The outcome is that the image is 4 bits per pixel. - Very small and the format compress the same ratio for every image.
