black roads fix by dk22pac

Problem

Playing San Andreas with Low Graphic settings (those are selectable in the menu) you can often see the 

'black road bug'.

It happens with textures that are placed far from camera.

Also, when enabling "High" graphics settings in the menu, an anisotropic filtering enables for some 

textures and this problem disappears.

 Reason

That problem is directly related to RenderWare and the way it works with mip-mapped S3-compressed (DXTn) 

textures *.

The last mip-map levels in mip-map chain (2x2 and 1x1) are just like "transparent" levels (because it's 

impossible to compress such small amount of pixels, - DXT works with 4x4 blocks), but still, they must 

be filled with pixels from 4x4 level. Or at least they must be ignored (and after this, we will have not 

10, but 8 levels, for example).

RenderWare (GTA-era versions) doesn't do any of these things when writing/reading TXD archives.

 *Thus, the problem happens only for DXT-compressed textures with (full-chain) mip-map levels. 

Solution

This .ASI plugin fixes this problem.
