And I'm trying to have it dynamicaly adjust according to what the player is looking at. I do this through a c_trace. It's been a while, and long while, since I've used 3DGS. So maybe somebody could explain to me why this code dosen't work Code: void calc_dof() { PP_DoF_init(camera,500,1000,1000,30,2); while(1) { c_trace(camera.x, vector(camera.x, camera.y, camera.z-1000),0); PP_DoF_SetValues(target.x,target.x+500,1000,30,2); //beep(); wait(1); } When I had the beep uncommented it was beeping, so I know the code is working to that extent, but the focus is not adjusting. By the way the parameters for the DoF are this in Slin's code: Code: PP_DoF_SetValues(NearPlaneDist,FarPlaneDist,FarFadeoutDist,BlurRadius,DownsampleFaktor); -Johnny Thrash

But if I understand this right. By adjusting the near and far plane in the DoF parameters shouldn't it by all rights focus on the area between? -Johnny Thrash
