Rick Posted June 3, 2013 Share Posted June 3, 2013 If I make my floor csg 80.25x63.75 the show navigation works just fine. If I increase to 80.25x64 the green show navigation doesn't show up anymore. Is there some kind of size limit for navigation that would cause this? Quote Link to comment Share on other sites More sharing options...
AggrorJorn Posted June 3, 2013 Share Posted June 3, 2013 The green navmesh visual does't always show. I think this is because of the draw distance. I have tested with large objects that spanned 250 units and navmesh doesn't show up, but the pathfinding works. What I did note, was the engine doesn't like large CSG objects. With or without navmesh turned on, the engine gets a serious frame drop. The largest area I used for my projects that didn't cause this frame drop is approx 80 - 90 units. Somewhat similar to what you have. Quote Link to comment Share on other sites More sharing options...
3Dski7059 Posted June 4, 2013 Share Posted June 4, 2013 So, if you split the larger CSG into smaller parts, would the navmesh show up and frame rate normalize? Quote Link to comment Share on other sites More sharing options...

MikeClarke Posted June 4, 2013 Share Posted June 4, 2013 large csg objects have been an issue in engines for a v.long time, common practice was to break them down. No reason to abandon using them. Models etc take alot longer to produce than a csg construction so unless you are v.well versed (and fast) making them csg is the easier option for low budget developers who don't have a team of staff to do as there told.

Admin Posted June 21, 2013 Share Posted June 21, 2013 This has nothing to do with the performance problems BSP geometry can have with large open spaces, FYI. Quote Link to comment Share on other sites More sharing options...
