Hi!
I'm developing the LPPR (Porto, Portugal) scenario and I'm having the same problem. The scenario has been developing in recent months and without any problem. Now it seems that there are invisible walls in taxyway's and planes crash into them making the scenery inappropriate. Does anyone have an answer or the same problem? Has the last update of the xplane affected some scenarios? Some buildings were, but there was never any problem. In recent weeks there has been. It seems that from version 11.25 something has happened ... I created some HARD objects for the scenario and i never had any kind of problems. All objects ceased to be hard but the problem continued. In fact, collisions exist on the taxyway, where there are no objects / buildings / constructions ... Some help needed...

Hi, I have already seen the same problem while developing sceneries and creating hard objects. It often happens when the shape of the hard object is complex. On way to deal with that is to split the object in 2 objects (with the same origin) and attribute the hard behaviour to the most simple shape. A rectangular or even just a flat surface will often to the job. If you use Blender, ctrl+J or P will let you split the selected faces into a separate object or join 2 objects. On export , you then just need to use the layers (select an object and press M to place it in a different layer). You can also not bother with the layers and show/hide the objects you want on export.

Also, the ATTR_hard_deck will let you taxi underneath the surface, whereas the ATTR_hard will project invisible walls below the surface.

Regards,

Guillaume

Thank you for your help. In fact that was the problem. One object was created as HARD, although it has a simple geometry (it is a lamp next to the gates). Now that is no longer Hard and everything is back to normal. Problem solved! Thanks!

I don't know how you designed your lamp, but it could still be quite complex. Once I had to reduce a hard object to 2 triangles to get rid of side effects.

Moreover, hard attributes add a pretty heavy load on the computer, so Laminar Research advises to avoid using hard attributes, unless it really adds to realism, or you really want it.

All the best with your scenery development :)
