Zoom In fails

Hypo Dyne 5 years ago updated by ไอยดา สุรีวงค์ 2 years ago 3

When I try to zoom in (middle mouse wheel) using helix toolkit viewport it shudders, then refuses to zoom in. I can zoom out, but when I try to zoom back in it fails again. If I zoom out, go behind the model and then zoom in, it works sometimes, then I can go back around the front and zoom in.

Failed to paste example code.

I have found that if I add ZoomExtentsWhenLoaded="True" that I do not get this problem.

Again its to do with a camera having a target, and the camera won't zoom in when getting close to a target.
