Insert Menu\Shapes.pov
#declare Typ=13;   // height_field_img

Png's are propably handled differently because now in beta 3 (plain 
32bit) the height field is mostly transparent (lower max_trace_level 
gives a black height field). The png uses indexed colors and if you save 
it as an RGB png the output looks the same as in 3.6 (except gamma).
