why are the vd->ray->vv and vd->ray->pp vectors never filled? Do I need to fill them myself? If so, how are they filled?

Do you have MIP-mapping enabled for the shader? Where are you accessing these vectors? Are ->v and ->p filled?

I did so, but it doesn´t help. However, I believe it may be may fault. I am accessing them from within a volume shader with no surface calculation (it´s an environment shader).
I guess that´s why they are not filled? ->v and ->p are filled.

I guess I should have been more explicit, but did you set SHADER_MIPSAT in MaterialData::GetRenderInfo()?

If you did that, then your explanation sounds likely.

yes, I did set SHADER_MIPSAT. If I´d like to fill them, is there a general rule of thumb what they should look like?

just to add: spot size etc. are of course not accessible either (resp. not filled)
