i have disabled the hiding function in object property,and i found the reason that left click disabled,when the physic disappear,the mouse can’t find the hitpoint on objects,and can’t positon coordinate。
now,there only one problem,how can i active physic??
By the second button do you mean the automatic tour button (in red)? :
When the automatic tour is active (the button blinks) the camera position is updated automatically, so the left mouse walking and physics are disabled. You need to first disable the tour to enable the left mouse walking.
hide to many objects or poly,may cause this bug。
hide one or two floor may be fine(some times is not),but hide all this sense must be cause this bug.
i also find strange bug,the objects not be choosen “walk on” ,the phyisc must be disappear after unhide.
the objects is choosen"walk on",the physic seems to move on z-axis after unhide;
by the way,i use 3dsmax2014.The sense contains many groups,and export to fbx format.
Please test again, we have fixed the bug for scenes uploaded to Shapespark hosting (for local scenes the fix will be included in the next Shapespark desktop app release).
