# Bimpas File Format

bimpas files are associated with Xbox elite they were the precursor to Armed Assault's rvmat files.

In both cases they define a series of textures for p3d models (and wrps)

The new Visitor 3 graphical editor tool refers to bimpas files as:

- rvmat surface materials
- bimpas transition materials

- rvmat files are a series of paas
- bimpas files are a series of rvmats

### Rapification

Ordinarily, these files, if binarised, are rapified in the normal xbox/arma manner

some files, possibly in error, contain substituted space characters for zeroes.

### Examples

```cpp
class Pass0
{
    material = "ca\introofp\ps.rvmat";
    texture = "ca\introofp\ps.paa";
    tlAlpha = 1;
    trAlpha = 1;
    blAlpha = 1;
    brAlpha = 1;
};

class Pass0
{
    material = "LandText\az.rvmat";
    texture = "LandText\az.paa";
    trAlpha = 1.000000;
};

class Pass1
{
    material = "LandText\ba.rvmat";
    texture = "LandText\ba.paa";
    blAlpha = 1.000000;
};

class Pass2
{
    material = "LandText\_N.rvmat";
    texture = "LandText\_N.paa";
    brAlpha = 1.000000;
};

class Pass3
{
    material = "LandText\Dl.rvmat";
    texture = "LandText\Dl.paa";
    tlAlpha = 1.000000;
};
```
