Damien, Ken, Zero-sized cube problem is fixed.
This problem was caused by OpenCollada's own float-to-string conversion functions which don't work correctly on 64-bit systems. The fix was to use sprintf. The disadvantage of using sprintf is that precision has to be limited to N digits in fractional part. This patch modifies conversion functions to use sprintf with 6 digits after the decimal point stripping off trailing zeros. The patch is on the wiki: http://wiki.blender.org/index.php/File:Opencollada_ftoa_patch.diff Tested on 64-bit Mac OSX 10.6. The original float-to-string function looks like this: http://www.pasteall.org/11155/c It only works on 32-bit. On 64-bit, it at minimum ignores the sign. If anyone knows how to make it work on 64-bit, that'd be a real fix!
