I've been mapping in HL2 as long as anyone... but I've never got an answer... or just dealt with with this problem... but it seems to me that smoothing displacements is off. Smoothing on Face Normals on a horizontally laid displacement works just fine. But I'd love to smooth out on the X and Y axises and fail every time... when you do it they vertices clump together and bulge out rather than being evenly distributed. Does anyone know a way around this or am I attacking the problem wrong? Mmh ?
