Before buying that package, I must have seen all Vue tutorials on the net and I read all the pages of the official Vue manual. I made several renders of interior scenes and for each I tried many different light configurations. But, even with all this on my background, when I read the InteriorPak manual, I went "aaaah!" several times. I learned several things there that are very valuable for interior renders. Just in my latest image, I couldn't get the lighting just as I wanted. So, I thought, let me go read Chipp's manual again, maybe it'll shed some light. And it did.

If you want to make interior renders, that manual is well worth the price of the package (well, I'm assuming you don't already know the tecniques and theories explained there, of course - I knew only a few). The rooms and furniture that come with the package are cool and are a good start for your experiments but you can build a similar room more or less easily and you can find lots of free furniture in many places in the net. I used those once but I'll probably not use them again. Those are not the point of the package, the point is the manual. You could see the objects as a bonus item, being the manual what you are really buying.

This is, of course, just my opinion.
