Corona for 3ds Max Features

CoronaLayeredMtl

Requires Chaos Vantage v2.3.0 or newer.

CoronaRaySwitchMtl

Empty channels require the "Rendering of opacity maps" option enabled in Vantage. This option is enabled automatically when using the "Open scene in Vantage..." option. However, if the scene is exported to the .vrscene format and loaded or merged into Vantage, you need to enable it manually. You can find this option in Vantage under Render Settings > Advanced > Materials > Opacity maps (clip mode) or Open Render Settings button > Enable rendering of opacity maps.

CoronaSelect Material

Standard bump

partial

Most maps other than Bitmap are ignored by Chaos Vantage.

Normal map

partial

Normal maps and/or shaders work as expected when using a simple setup (Bitmap > Corona Normal > Material bump slot), however they may not work correctly in more complex scenarios (e.g. mixing two Corona Normal maps and connecting the mix with the material bump slot).

Normal displacement

partial

Vantage always applies smoothing to geometry edges, similar to using mesh tessellation or subdivision.

Vector displacement

Per-face normal

Per-face vector/mixed

Only single vector displacement or per-face normal displacement is exported. 

Water level

In case of per-face displacement, only the lowest water level is exported. 

Triangle meshes

Hair

Corona Proxy

Corona Proxy is currently exported as a regular mesh.

Corona Decal

partial

Requires Chaos Vantage 2.4.0 or newer.

dimensions

bend

partial

Bend-width only.

Corona Decal
Max Angle Blur

partial

There may be minor differences between the appearance of the Decal in Corona and Vantage. Specifically, the center of the Decal can be partly transparent in Corona, but it is always opaque in Vantage.

bump

partial

Decal bump always replaces or adds to base; the Base only mode is exported as Add to base.

displacement

Displacement is always taken from the base object.

Currently scattered instanced export as individual instances. Future optimizations are planned.
