    I'm happy to confirm that is not the case and to correct Matt, and anyone else.

    Reading between the lines is a perilous path to pace and pontificate on.

      Is this deprecated or replaced?

        Yeah, by reading between the lines it is clear that you are blaming very experimental feature. Why should it be shame that such experimental feature has bad UI? I understood your post the same way as everybody else.

        Sorry for OT.

            I was just wondering if convex hull collision was on the roadmap for use in clothing... I saw the new tapered capsule and it really helps alot... great work guys!!


              [QUOTE="andrlet;n1485732"]Could someone please point me to the "list of supported webcams & HDMI capture devices" mentioned under VR/AR Updates? Thanks so much!

              I too would like to know as well. In the past there was a calibration folder, with a calibration map. This is no longer available and even though a mixed reality camera pawn is now available, the blueprints for masking and despilling have errors.

                It is a shame because, it is an unfortunate situation. In action, it is a shame Epic Games have not (currently) allowed feedback to mould and shape this important feature further than they have.

                So, my figurative comment stands, as you have misunderstood the intent of my original post and the subsequent follow up to clarify the post.

                I, too, apologise for the off-topic rebuttal. We are all adults here and hope this topic is now fully clarified/understood in the manner for which it was intended originally, without the need for further demarcation.


                  Please update Stand alone VR solutions.

                    This is the only feature I am interested in, even though the hardware is far off I would like to start using it 2 months ago.

                      I'd love to have such a list too. It would be really helpful.


                        I am to understand that it will not run on OSX 10.12 anymore?
