I'd noted the change in Collada export between Sketchup 7.0 and 7.1. I've been using Sketchup to do models for a game using CryEngine2 (game is Blue Mars). Sketchup is useful because the supported tools (3DS and Maya) are a bit beyond my budget at £3k

The accepted wisdom for both this game and the Crysis mod community is that 7.0.10247 is the last Sketchup version that can be used to create models for the CryEngine2. I've certainly wrestled a lot with 7.1 and models that exported very nicely in 7.0 don't work in 7.1.

It may be that the tools provided for the BM and Crysis community seem to be based on Collada 1.4.1; Not sure what 7.1 exports as .. I'll check

Note: we're not talking complex models either. My test item is two blocks and two textures.
