bump mapping

Blitz3D Forums/Blitz3D Programming/bump mapping

is there any function out there, with which you can type "entitybumpmap (entity, "bumpmaptexture.bmp")" before the loop and "updatebumpmap()" in the main loop??? I've been on a hunt for a function of this sort, without any success. I hear tom's DLL can do this, but I cannot find it anywhere. Can anybody help??
