Sorry about my "cut-n-paste"-english there, but I hope you understand
the issue anyway! :)
Hi!
The Collada exporter in sketchup exports transparency in the wrong
way. Since Collada 1.4.1 using opaque="A_ONE" (the default) in the
<transparent>-element assumes that a value of 1.0 is opaque. In
Sketcup it seems that all materials are exported with the
<transparency>-element set to 1 - opacity, which makes all opaque
materials invisible, and transparent objects have their transparency
"inverted".
Please check the Collada 1.4.1 release notes
athttp://www.khronos.org/files/collada_1_4_release_notes.pdfpage 8
(page 12 of the pdf) and correct this issue.
Thanks
