      Hi Dementium4ever and _Scribbler_ Thanks a lot for this.

      I am attempting to use this in VR and I'm not seeing any results. I have a VR pawn that has a camera. I am also making sure the Media player is playing in the Level Blueprint and the video file is in the Movies folder. I seem to be getting audio, but no video in VR (projection does work in non-VR mode) Any ideas? Maybe a way to connect to the two cameras in the level?

      Thank you!

        @_Scribbler_, RyanB and @Dementium4ever, what an amazing project!!! It should indeed be native in UE.

        I'm trying to use a screenCapture2d->renderTarget as a texture but get errors for all the material instance's vector parameters:

        Blueprint Runtime Error: "Accessed None trying to read property Material Inst". Blueprint: Projector_Final Function: Execute Ubergraph Projector Final Graph: EventGraph Node: Set Vector Parameter Value

        Any clue on how to make it work with scene capture?

        I'd like to be able to use several instances of this setup and limit its texturing to selected objects only, would it be possible to implement such option?


        Thank you in advance.

          Did you ever get anywhere with this? I'm trying to do the same thing basically.

              Hey all that might still browse this thread, I've been trying to project an image that is twice the size of the current projectors aspect ratio. I edited the vector 1 and vector 2 values in the Blueprint to 0.5 as seen in the image and in the preview display am getting exactly what I want in the next image. The final image however shows what happens when I hit play and I've tweaked every gosh darn value I can and it doesnt seem to be helping. Any advice or help would be extremely appreciated
