Hi there! Often you have to link 2D and 3D content. It usually takes some time, which is very expensive. Why not to do it right away in the Corona VFB? I created a small video to demonstrate this feature. So far I have not seen such a function in any renderer. I think it will be very useful to many people. Customize the composition, materials or colors, where you need to add new content, etc.

I am not saying this would not be useful, but generally such stuff should be done in post production apps. If other users vote for this, we will consider it. 
It can speedup time-consuming process of composition of your 3d-model with existing 2d-design, e.g. webpage or magazine cover, etc.
Well, it’s quite similar to another much wanted VFB feature: Logo overlay.
So +1 from me
Another case. When you do an animation, sometimes it happens that you can accidentally shift a camera a little while doing some changes to the scene. You then will need to find a way to overlay shots with one another to restore the camera position, in order to combine previously rendered part of animation with new frames of updated scene.
Diverting off topic, but the problem you have stated can be solved by a camera (or other types of data) publishing system. That doesn’t take long to script using Maxscript, then you will always have protected data that you can re-import from. This took me about two days to make and has saved me countless times.
And what if you need to change logo later and all your renders saved with logo? this should be made in post in non destructive way. you can batch apply logo in any image software for ex xnview in couple click.
webpage, magazine making in photoshop, and logo for print needs in CMYK! for web sRGB you still need photo editor for color management so it useless request imho
nice video though)
The idea of this function was’t to replace one software with another. This should speed up the process when you need to put three-dimensional content in a frame relative to two-dimensional content (which has already been made).
+1 I believe i mentioned this previously. The reason being that the only reason i use Photoshop alot of the time now is to add a logo or watermark given the control we have in the VFB.
This has been my fav tool in pre Corona times. It does not work well together with Corona, needless to try out. And for any “how to” stuff: Those are either not usable with DOF (anything linked to the cam) or - if it’s about scripting, like the scripted plugin above - it does not work with Corona VFB.
Good Luck
The plane in front of the camera is a solution and I have to use it. But, the plane in front of the camera has negative consequences. Atmospheric effects, depth of field, additional load on rendering, a waste of time in the end ..
Surely if this is something you do regularly, just make a Photoshop Action to do it? (then you can just point the action at a folder and it’ll add it to a set of images).
If you’re thinking of Corona as a photography-based tool (as I do), this would never be incorporated into a camera. At best, some can add a watermark via an app and wifi sync, but it still wouldn’t be in the camera.
Likewise, I can’t see any photographer wanting to stick a transparency w/ logo on the glass of their lens (the equivalent of adding a plane in front of the camera).
Haha nice exception.
But you could do that with renderstamp… right?
Yes, but not in that lovely yellow :]
BTW, this doesn’t mean that i vote for overlay request. IMO, this should be left for photoshop.
Just adding similar topics:
https://forum.corona-renderer.com/ Watermark In VFB
https://forum.corona-renderer.com/ Create Watermarks
I would also vote against adding anything like this to cVFB (reasons in one of the above), but I would love to see Corona team investigating if there could be reasonable script support doing something like that matching Coronas (VFB-) technology.
Good Luck
Unfortunately, the idea is’t understood. For some reason, the whole discussion has been reduced to adding watermark. You can add watermark in Photoshp (static render) or AE (animation).
By proposing this function, I meant other things ((.
Logged basic version of this “logo overlay” in our internal tracker (I am now hiding away to avoid the wrath of the gods).

If we did not fully understand your request, then please explain how exactly you would like to use this. What works best for us is “I would like to use this to…I would also like to use it as a way to…oh, and additionally it could be used to…, which would be really cool”.
So far I understood that you would like to overlay an existing bitmap on top of the VFB, with transparency respected, and in your video there is also an option to decide what is in front and what is in the back, based on scene alpha and/or zdepth.
As i imagined it in the other thread not only could you watermark and choose to tile that watermark across the whole image (perhaps with transform controls) But also just add any image in a corner, with transparency respected.
I see why some prefer to do it in post but when we arent doing any post or CC it would be amazing to just have the output ready to send to the client especially for test renders etc.
Also removes a step in an animation potentially speeding up encoding.
