Beginners Questions #11

Hi Greg So many thanks for your great project. At present I am trying to get this to run with my own equipment and now I have several questions.

1) I own five Vive Trackers and 4 Basestations, all from the 2 generation. These work fine without controllers or headset. During my own first approaches I have been setting the Deviced using "GetTrackedDevicePositionAndOrientation". This works perfectly well, but I always must use the same sequence switching trackers on at startup. Now I do not understand how you talk to your several trackers which all seem to be called "special_4". I would be glad about some clarification on this.

2) I have access to a Blackmagic Micro Studio camera and a Blackmagic 8K pro card and so I replace the Media Source. Is there anything else to adapt, or should it run now?

3) I do not understand your hint from the Readme: "you will have to go back into VPStudioBackground1 & 2 and the garbage matte passes and set the "camera source" to override and the Target Camera Actor to VPCamera 1 & 2 again". My problem: I cannot find any "Target Camera Actor" in the Details?

Hoping for your patience I remain with kind regards Mischa mischa.schaub(at)virtualvalley.ch

If you have not already checked it out, look at the tutorials on my YouTube channel here https://www.youtube.com/user/GregCorson I will mention some of them by name below.

  1. I use Motion Controller components instead of "GetTrackedDevice...etc" These have the advantage of staying assigned right regardless of the order you switch them on. At least in the latest release of VPStudio here, my trackers should be setup as Special_1, Special_2...etc. To make them work you have to setup vive tracker roles and mappings in STEAM. Look at "Vive Tracker Roles Tutorial" and "Tutorial 3 Vive Controller" for more details. Steam's system can be kind of confusing but once it is setup it works well.

  2. Setting up a media source according to the docs on the "Pro Video Quickstart" is the main thing you need to do. You also need to make sure that source is connected to your MediaPlate in VPStudio.

  3. This is down a ways in the garbage matte and VP studio background passes in the "input" section. If you are having trouble finding them, select one of these passes and type "camera" in the search details box of the details tab.

Hope this helps, let me know if you have more questions. You can also ask for help in the discord chat group here: https://discord.gg/ReEhkhc or facebook here https://www.facebook.com/groups/virtualproduction

Hi Greg Thanks for your helpful answer. I am travelling at the moment and will only find occasion to sit down again at my workstation in a week's time. Will report back, looking forward to this. Kind regards Mischa
