i still have problems displaying billboards. i still do not understand how to use the mode when displaying images. ill try to explain what is happening.
i changed the example code "06 - Pathfind.cpp".
Code:

/*
UInt modes = IndexToFlag(RM_SOLID);
Game::Static::drawPrepare();
return modes;
*/
//second way
UInt modes = 0;
Game::Static::drawPrepare();
return modes;
}

and i changed the Access (in Default) for all rock objects in the path.world.
Billboards are not displayed correctly when the player moves. see screenshots.
in my game they were not displayed correctly when i start to use mesh-> drawBlend () for some objects.
before calling the method need to set the matrix (MatrixIdentity).
