the RenderAction by default does not write into the depth buffer when
rendering transparent objects, which makes sense when rendering semi
transparent objects (i.e. ones with 0 < alpha < 1).
You can change that by calling raction->setZWriteTrans(true). I don't
know if VRED has an option for that, sorry.
Hope it helps,
Carsten
