Summary	0006041: Renderer doesn't take "translucent" keyword into account
Description	Toggling the "translucent" global keyword in the Advanced tab > Global Settings seems to have no effect on the preview - it's still fully opaque. I believe this should have the same effect as having 0.5 alpha?
Tags	No tags attached.

Being marked as translucent has several implications: any translucent material is implicitly noshadows, it doesn't contribute to the depth fill buffer pass (which is the main cause for the resulting translucent effect) and it affects a couple of other checks and flags in the renderer I didn't fully explore. DR recognises the translucent keyword and calculates the correct opaque-ness of a material, but during rendering this is not fully respected yet.
