Set Corona Renderer as your render engine:
The first step is setting Corona Renderer as your main render engine.
Go to Rendering > Render Setup > Common > Assign Renderer,
and set Corona as the production renderer.
Add a CoronaSun:
We need some lighting in our scene as well. Let’s use the Corona Daylight system
to get some simple realistic outdoor lighting. Go to Create Panel > Lights
Category > select Corona in dropdown menu and create a CoronaSun.
Your first render:
You can now do your first render. You will immediately notice that the scene
renders extremely bright. This is because the default exposure is set up for
an interior scenario with the Daylight system. To compensate for an exterior
scenario, just set Exposure (EV) parameter to -4 in Corona Virtual
Frame Buffer’s ColorMap tab.
Add a CoronaSky:
Go to the Modify Panel for the CoronaSun, and click Add CoronaSky environment.
This will add a CoronaSky environment (which is connected to CoronaSun) to the
3ds Max environment map slot.
Corona Interactive Rendering:
You can work on your scene with realtime feedback using the Interactive Rendering.
To activate the IR preview in a viewport, click on the viewport label (where it
says “top”, “right”, “front”, “perspective”, etc…), go to Extended Viewports,
and select “Corona Interactive”. Alternatively, you can run Interactive Rendering
in the floating Corona VFB (as shown in the video).
Adjust lighting with the Interactive Renderer:
You can tweak scene lighting and shading and observe realtime updates in the Corona IR preview.
Adjust tone mapping with the Interactive Renderer:
You can adjust tone mapping settings in the Camera tab of the Render Setup window
and observe those changes in realtime as well (or in the Post tab of the Corona VFB
in case of using the floating IR window).
From here on, you can keep experimenting with Corona’s light, materials, and maps. Have fun!
Convert scenes to Corona:
You can convert an older scene using the Corona Material/Lights Converter. It comes
with every Corona installation. To run it, right–click in any viewport, and
select “Corona Converter”. All materials will be converted to the native Corona format,
so you can easily re–render your older scenes with Corona.
