Reflections in 3D

Hi there,

I have some cylinders sittingon a flat plane and I want to set up reflections. I've been messing the the reflect tool (3RR) but not sure how to use it. Some tips would be highly appreciated.

TIA

Not easy to explain.
Here is an example I made

I'll post the comp when I get in front of my computer.

if you just need a reflection of the cylinders on the floor, then its not so hard.

you need to duplicate/instance you camera and mirror the second camera on the ground plane.

then you create 2 seperate render3d nodes. one with the original camera and one with the mirrored camera.

now you have 2 renderings: the normal "beauty pass" and a mirrored one, the "reflection pass"
this can now merged together

like in this video:

you can also render the reflection first, modify it (e.g. a blur) then use the catcher to project it on the ground floor:

for reflections on the objects itself its gets a little bit more complicated, because fusion has no raytracing in rendering.
you could create a cube map with 6 cameras and 6 render3d nodes, which then get into the reflect material
you can see it in this video:

Thanks guys,

That is very helpful.

Cheers
