How to render a 3d viewport with sprite snapshot

I have a viewport object. I have managed to render the camera over a big yellow box. That means it works, I think, but my 3d objects that were over the yellow box weren’t visible; and neither was my 2d fishing pole, over the yellow box, which is supposed to be there.

Sitting here and considering however, I really don’t know what I am doing. What I want to accomplish is having, as I said, a 3d viewport. I also want to render a 2d sprite, the fishing pole (though a weapon works just as fine in this case) on top of the 3d screen.

Typically, I would do this by using layers, and using a 1st person 3d camera on the base layer while having my weapon or fishing pole at the bottom center, sticking up, and for some reason layer 2 would be perfectly normal. However, I don’t know how to do it like this here.

Grrr … can’t there just be an extension for printing a camera onto a viewport, instead?

I’m trying to create an effect like really old pseudo-3d rpgs, but using 3d, because that’s easier and would probably be cosmetically better, too.

Hello,

Have you found a fix for this? I’m having the same issue.
