Innis, It sounds like some polygon normals are inverted. This is pretty common after joins. After doing a join on objects in Blender, select your object, go to Edit mode, and on the button bar find the Mesh Tools More menu. From there, select Draw Normals. The normal is a line perpendicular to the surface and extending outward from the center of the polygon in the polygon's facing direction. Generally you want all normals pointing out, indicating the facing sides are on the outside of the object. I suspect you'll find some normals are not pointed the right way.
To fix this, you can select the problem polygons and then: Mesh Tools-->Normals-->Flip (also available from the specials key: w), or you can also try to recalculate all the normals to face outside, (ctrl-n in Windows). Usually ctrl-n does a pretty good job of resetting normals of simple objects in the right direction. Feel free to contact me off-list if I can be of more help. -Gary, aka Buckaroo on MP On Thu, Jun 11, 2009 at 11:23 PM, Innis Cunningham<inn...@hotmail.com> wrote: > Hello All > I am trying to build a hangar with Blender 2.48 not a hard task you might > say > but for some reason when I join two objects to one some of the sides become > single sided that is they become transparent from one side in FG.If I leave > them > as separate objects they show double sided in FG.Does anyone know what I am > doing wrong?. > > Cheers > Innis > > ________________________________ > Find your next place with Ninemsn property Looking for a place to rent, > share or buy this winter? > ------------------------------------------------------------------------------ > Crystal Reports - New Free Runtime and 30 Day Trial > Check out the new simplified licensing option that enables unlimited > royalty-free distribution of the report engine for externally facing > server and web deployment. > http://p.sf.net/sfu/businessobjects > _______________________________________________ > Flightgear-devel mailing list > Flightgear-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/flightgear-devel > > ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
