I am working on a building in GMAX and created an API thru FSRegen and placed using A260B154. Now the strange thing is that the building disappears when viewed from certain angles. The GMAX coded building itself when exported directly does not have this issue.Do you think the API created by FSRegen has a coding problem?ThanksShez

>>>Do you think the API created by FSRegen has a coding problem?<<<*** Probably a quick way to find out would be to view the API's RefPoint value for "V2= " and try increasing/retesting it if it's lower than your desired viewing radius in meters.***J.R.

Whoops interesting that there is no V2 value...Shez

Hi Georgio,Just checked the api generated with FSRegen. It works fine except that in some cases the 3d object will disappear when viewed from certain angles. On the advice of JRM I looked at the api code and inserted a V2 value after the V1 parameter and this problem disappears.Maybe something for the continued development of this great utility. :-) RegardsShez
