matte oject in VrayRT?

[gonsolin]

Hello ! I'm trying to render a car with a vray plane and an hdri in background.
My plane use the matte object properties of the Vray properties menu. it renders well with Vray but failed to render in the vrayRT active shade window.
Does VrayRT Do NOT support that propertie ?

It works fine here on a simple test.

Best regards,

the scene needs a light for matte working !

ok, i solved my problem but there's still a bug:
If you only let an HDRI environment as lightning, you get a dark plane instead of matte shadows when using VrayRT active shade window. that problem does NOT appear when rendering in production mode.
To fix this you need to add a vray domelight: it work but can this bug be fixed?
