I am using Davinci Resolve Studio. I have some footage and camera tracked the segment, no issues. Next, I tried some 3D text, it worked. Then tried a blue portal I got from here, thanks, and I cannot connect the blue portal to the 3D merge. So I guess it has to be a 3D asset? And or am I doing this wrong? Any help is greatly appreciated, thank you.
I believe what you are looking for is a 3D Card. You will need to use a card to get this element into the 3D space. In Fusion/Resolve the node is ImagePlane3D.
I think this tutorial might be helpful for what you are trying to do.
Thanks, I have seen this before so time to reload the video.
