Hi All, Back on Wednesday I wrote:

As it turns out the Warning above was being emitted any time there was a transparent bin, even when the bin had entirely correct depth values on all leaves. What was missing for this warning message was a : if (detectedNaN) ... Pretty basic error on my part, something I spotted on Thursday morning, fixed and checked in. If you did see these errors and thick that something was wrong try an svn update and then redo the tests. Now CullVisitor/RenderBin should only emit warnings when something is genuinely amiss. The root of this investigation that led to the above warning addition was looking into a crash in a std::sort<> when the list had NaN depth numbers being compared against. The actual cause was an invalid DOFTransform containing a put matrix with nan's in it. This put matrix was in tern generated by the OpenFlight loader, which was handling erroneous data but not catching the dodgy data, instead attempting to do divide by zero. This is now caught and a warning emitted before any dodge transforms are created. So this should prevent the particular failure path that I was investigating. The OpenFlight fix won't fix existing .ive or .osg models that have erroneous DOFTransforms in them though, so you'd need to recreate this files from the original .flt source.
