SketchUp - the ultimate tool for creating architectural structures for levels.

Miscellaneous Forums/Content Creation Tools/SketchUp - the ultimate tool for creating architectural structures for levels.

Looks good but it is primarily designed to make architects 2d sketches from 3d models. Could be that the geometry is not really optimised for real-time 3d and there is no occlusion system.
Its also not that much easier than any other level creator - in fact it can get quite complicated - just check out one of the demos about making roofs - had me totally bamboozled ( there again that's quite easy).

Certainly worth a look though but maybe a bit overpriced.
Given the choice I would much prefer to use Quill3d or CShop.
