Put every 3D geometries inside a composition to multiply it's renderers
Select the 3 geometries we already created and press
to put them inside a Compo
(I'll rename this composition "3D compo")
You can also do it by selecting your 3 geometries and
Right Click > Make Compo
Now select this "3D compo" composition and either
Right Click > Add Renderer
to add a renderer on this composition.
Turn this newly created renderer in "perspective placement". This placement type will allow you to deform your image to adapt it to a different perspective.
How to manipulate a Perspective 2D renderer
Now go in edit mode (red circle on the screenshot below) and select the perspective placement renderer. Now you can use the little green points on the corner of the layer to move and distort the image. I placed this second renderer as showed on the screenshot below with a 25% opacity.
You can either place it with your hands or copy "Position A/B/C/D" of the renderer's parameter if you want to copy it exactly.
You can like that multiply the renderer with a very few performances cost and so render complex and detailed environments using this technique and your imagination.
Add fancy effects
Let's add a Blur
with those parameters:
Add now a "Add contrast+" Exposure
Right Click > Modifiers>Color>Exposure>Add contrast +
And put a vignet radial mask over the exposure modifier:
Right Click > Masks>Radial Mask>Vignet
Now uncheck the "Inverse" Parameter of the radial Mask and go in edit mode (green circle) to place it with your own little hands or just reproduce the values in your keyboard.
And to finish it off, Add a Chromatic Aberration
Right Click > Modifiers>Stylize>Chromatic Aberration
I really don't know what conclusion I could make from all of this....
Oh yeah, for thoses who find that composition too dark, you can add this little omni light next to the others (and don't forget to deactivate it's volumetric as we saw before)
and here what you will get :
