Hi Ced, those are probably just too many constraints that you're trying to apply all at once, I don't think you're going to be able to get a good results with so many constraints.

In order to solve the constraint of the bottom being closed and being a single surface, you would need your loft profiles be elongated at their bottoms and touch each other at a single "pole" point as in the example I posted previously here: http://moi3d.com/forum/index.php?webtag=MOI&msg=8288.12

Using a lot of sections in either regular Loft or Network will tend to apply too much pressure on the generated surface and it will have wiggles and bumps in it as it tries to force a surface through too many large changes in shape in too small of an area. Using Loft with the "loose" style is more tolerant of that and so you might try working with that way of lofting rather than regular loft. Loose loft will make the surface only generally guided by the profiles rather than forced to go exactly through each surface and so it applies less pressure on the result.

Under normal circumstances you would close off the bottom of a shape like you're showing there with a separate planar surface, it will be difficult to try and make the bottom in your case to be part of the same surface as the sides, so you may need to use Flow only for the sides and find some other way of positioning your texture pieces on the bottom area, since it is flat maybe you should just copy your texture objects to there using Transform > Orient instead of using Flow for that area.
