It is not possible to apply a shader to the vehiclegrunge256 texture after the latest update.

[ZbyK77]

Describe the bug

After the latest update (probably “Fix setVehicleDirtLevel (#3837)” r22823), it is no longer possible to apply shaders to the vehiclegrunge256 texture.
This blocks many opportunities for shader use.

Steps to reproduce

1. Run example code (Based on shader_tex_names)
   shader = dxCreateShader([[ float4 GetColor() { return float4( 1,0,1, 1 ); } technique tec0 { pass P0 { MaterialEmissive = GetColor(); } } ]]) engineApplyShaderToWorldTexture(shader,"vehiclegrunge*")
2. Compare the results in the release after 22823 and before 22823.
