bit of a weird one this, i dont know how i did it but if i have anything selected and the click on empty space it doesnt deselect like it it normaly does.
it either keeps the current selection or selects something else.
this also continues if i copy the project.
so im guessing something has been checked on or off
ive gone through all the settings from another project where this doesnt happen and made sure they are the same in the one where it does but nothing is different.
edit - just discovered this only happens in perspective view and camera view.
not been able to reproduce in a fresh project.
and i could not say what the steps are to get to this
the mesh it selects depends on the perspetive view angle and which blank area you click, change the view or mouse position and it changes what it selects.
its not a huge problem just have to be carful not to move the object by accident, its mainly just a bit wierd
So it looks like there’s something related to that model that causes it not to render correctly into the Editor’s pick/selection buffer. If you can somehow share that with me, we can log a bug and investigate further.
