Damn that's a downer then - soooo much extra legwork.

I guess you have tried exporting as another file type besides png?

Do you get the same "inversed" alpha problem if you export a targa etc?

I dont know if this applies to what you are doing but for 3D object renders, here's one quick way that works for me:

1. In atmospheres select - "Effects" - then "Others" then "Black Back" (Solid black sky for use as a mask).

2. Export using broadcast/render to disk/options: save colour picture, select "TARGA", when you click ok the 'picture format options' dialog box comes up, select "16M colors" and SELECT the checkbox for "EMBED ALPHA INFORMATION" - click OK.

3. You can also elect to save an ALPHA MASK or DEPTH MAP at this stage - depends what you are doing. Click OK.

4. Click render.

One thing is if you are importing a 3d object like a "House Door Key" from Maya or Max into Vue and want to do a simple texture, rotate and render, if you apply a reflective material in Vue like chrome to the door key, it will render black if you dont adjust the material as it reflects the black environment. Duh I dont know Vue that well so I am sure there will be a work around.

These targas work fine in Motion but should be ok in After FX or whatever.
This is probably a very retarded way but I am not a Vue expert.

AFAIK there is a problem with the sketch designer for Poser 7 sr1.  There are a couple of threads around. 

Although I can load and change sketch styles in the designer, I cant get it to render any sketch style apart from the default from the document window or to save sketch settings properly.

Just thought you'd like to know it's not just you.

I used mainly 3ds max previously. I downloaded the online Vue5 Pro trial and have been testing it importing PZ3's from Poser 6.1 and it works great except that the trial's animation length limitation is 5 seconds - just barely enough to check out a walk cycle. But I am so blown away by Vue so far and will be downloading the infinite trial as soon as its released to try out the ecosystems.
