parang ambient occ. pero litaw na litaw nag wire.. thanks!!!

try mo apply sya ng vray material tpos sa diffuse lagay mo vray edges text tpos pillin mo kung anung kulay ang gusto mo....lalabas yung wire mesh ng model mo....

cge, I'll try that...salamat po

for a quick hidden line look in your renders, facemap this via UVW Mapping or thru the material setting: (works even for scanline)

From Drop Box

where black is the color of the outline, white is the surface color.

thanks v_wrangler.. i tried it.. worked well. very clever
