This patch updates Evolva to version 1.2.944. It upgrades the Evolva engine to support diffuse bumpmapping on high-end 3D hardware, such as the NVidia GeForce, GeForce2 and the ATI Radeon. This adds a huge amount of detail to the scene as lighting is calculated per pixel instead of per polygon.
I uploaded this here for backup reasons, because FilePlanet link is dead and Interplay support page may not be around for much longer. GOG release comes with this patch already installed.
