DCP Rim Map

When you have no backlights, fake it with Rim Map. Extract preset to: C:\Users\xxx\AppData\Local\Autodesk\3dsMax\2017 - 64bit\ENU\en-US\plugcfg\DataChannelPresets Then in your DCM, load Vu_RimMap as a Preset.

It is of course camera dependent, so make sure you pick a camera in the Vector Node.
