Hi totalvortex, thanks for your explanation. Now that I understand, I will have a closer look on the benefits of having two pairs of hands. But still, could you make the shadow a toggle option?
About physics objects in the viewport, I wouldn't mind a little slow down. If my systen couldn't handle it, I would prefer an upscaled system, not a downscaled software. I have other leap motion software that has a dozen simulated objects in the viewport and there is no performance problem. I find it difficult to simulate e.g. a writing hand without actually seeing the movements of the pencil it holds. If this can be aided with a simulated object, it should definitely be done.
Regards
