light up my mesh

| I have a mesh, parented to a pivot, parented to another pivot, parented to the camera. More or less like this: ---------------------------------------- Graphics3D DWidth,DHeight,DDepth ScapeCam=CreateCamera() AmbientLight 0,0,0 CameraRange scapecam,1,1000 CameraProjMode ScapeCam,1 ScapePivot=CreatePivot(ScapeCam) aspect#=Float(viewheight)/viewwidth PositionEntity ScapePivot,-1,aspect,1 scale#=2.0/scapeviewwidth ScaleEntity ScapePivot,scale,-scale,-scale ScapePivot=CreatePivot(ScapePivot) PositionEntity ScapePivot,-.5,-.5,0 Scapelight=CreateLight(1,scapepivot) PositionEntity scapelight,0,0,0 ??????(other values have no effect?) (I create a mesh named QMesh representing a landscape here...) EntityParent Qmesh,ScapePivot --------------------------------------------- Now the lighting comes from the direction of the camera and I want it to come from the left, but I can't get it to work. Anybody any ideas? Much appreciated! |

| Directional lights - as the name suggests - just shine in the direction they're facing. Therefore, positioning them in the world has no effect - because they'll still be shining in the same direction - so is meaningless. Instead, rotate the light to point in the direction you want. e.g. RotateEntity scapelight,0,45,0. |

| Thanks... This did the trick. I should have known this...But I didn't...Or did I? This 3D-stuff still has me thinking around corners sometimes. ;) |

| You can also use PointEntity to have one entity point at another if you don't know the angle. |
