Hi,
I'm trying to find the best solution to add the reflection of a road that runs into the eye.
At the moment I created a scene with a street and a 360 ° room.
I exported a sequence of hdri.
In a new scene I put the video capture with the close-up of the eye as background.
I created a sphere and put it over the eye.
I have inserted the hdri sequence as environment.
The problem is material.
I tried to use Corona Shadow Catcher only with reflection properties but not work...
Suggestions?

I am afraid most users' imagination will be too limited to understand your issue. :)
Could you post some example images/drawings of what you would like to get, and what you are getting?
-
oof thats hard to parse.
But I think i understand what you want to do....
1.) load your footage of your eye in your environment slot with screen mode selected in your bitmap settings
2) Make a sphere that matches the position/orientation of your eyeball from the footage
3) give your sphere material a black diffuse with the amount of reflection you are looking for. give it full refraction with thin refraction turned on, add a CoronaFrontBack map to the opacity slot and make the front face side white and the back face side black.
4) add your Road HDRI into the reflections override, in the scene >scene environment rollout
5) change the offset of your hdri to match how you want it into look
6) go to the render elements tab and add CESSENTIAL_reflect pass
7) render your reflection pass and then comp it over your footage in your video editting program.

Thanks for reaply,
I've tried mferster's solution.
I attach a very fast test (the eye is an image not the final shoot)
There's much post production for have this result. I'm not sure if this work fine!?
What do you think?
The shoot (that I still have to do) will be animated, so..maybe can work fine..:/
-
This is a different post production, I think work better :/
-
How about just animating a camera moving along the corridor, and then overlaying this video on top of the eye footage in post?
-
I think you will lose the spherical effect in that way.
Then I started in this way thinking that was possible to catch only reflection with Shadow catcher material as native matte/shadow material in 3ds.
For the final clip I would like to try to give a different glossiness for iris and rest of eye.

I agree with maru, once you have your road footage, there's no reason to rerender it in 3D, unless the eye moves in three dimensions as well. Just add some spherical distortion on the sequence, scale it and mask it to fit the eye and comp it in post-processing app.

Yeah, this sounds like overcomplicating quite simple things to me, but I may be wrong...
