Multi Subobject Materials Change To Black

[Jet]

Whenever I use multisubobject materials with vray,
and im using vray basic, if i change the material bitmap channell number to anything other than 1, then I cant see the material thumbnail in the material editor, nor can i see it in the slot. If i keep them at 1, then i can see them, but alot of times when i do interiors, and exteriors, i use low poly modeling, Is there a way to stop that? Currently what I do is, i fix my material in another slot, tweak it, then after it is the way that I need it to be, i go ahead and get all of my id's matching with their polygon and uvw properties, and I copy it to the multi subobject channel in its order. But then if i need to make a change or anything, its kind of a hassle.
Anyone have any insight on this issue?

Any Takers?

any takers?
is it because im using vray basic?
i remember getting an email about updates to multisubobject material, but the only update that was available was for the vray adv.
is there any plan to fix this for vray basic users?

Hi jet

The same thing goes on with vray advance, either current version or 1.4x.xx beta.. Could be a general vray isue, but not related to the basic version..
Not helping, sorry

Yeah, it's a known bug. I haven't come up with a workaround other than similar to what you described on top of doing many test renders.

ok cool thanks!
i just remembered getting excited when i got an email about some fix with multisubobject materials, but when i went to download the update, it wasnt listed in my vraybasic section. oh well. I dont mind. i just copy the material with an instance, and i evaluate it in a non used material slot and when i get it right, i set its material id back to the correct one.

Thanks,

The problem's with multiple map channels not multi-sub.
