hi, i want to know why some objects don't reflect in water shader? i try to change flags etc, but not working..thanks for help

example?

here's an example: house are reflecting and bridge don't.
I don't understand why

Both object are models? The shader ignores models which flag1 is set.

i set light calculation to low quality in map compiler and the problem has gone but still it's not solve that problem, because in other map thees entities ar are reflected on high quality light calculation..
