All,

Has anyone encountered their scene going blank when the mouse click and drag? It’s inconsistent for me, and doesn’t spit out any error messages. There _might_ be a correlation between the error and part of the scene being off-screen, but I can’t be certain. I’ve encountered it a lot today, and generally used right-click drag first, then left-click drag would sometimes work without going blank.

Thanks,

Jason.

is this for a 2d scene? I had a problem, which should have been fixed, that basically zoomed to 0 when a drag was 0 length… Does center!(scene) undo this?

Hi Simon,

> is this for a 2d scene?

Nope, 3D. In all it’s glory. 🙂

Yes, this worked. Thanks! I suppose this indicates the 2D bug is also  
latent in the 3D rendering as well?

Thanks,

Jason.

Weird, I’ve never encountered this in 3D… guess I have to try it out!
