Just for the record ...
...there are several things like this out there that might solve this problem, and I'm sure Steve's is as good or better than many ... BUT ... we are cannot recommend changing anything officially from RTMM.
Our method of solving the missing objects problem is relatively simple, we get rid of objects that don't work, put in ones that do and re-upload the scenery location and label it as "DX Ready." Changing out the objects, (making our locations DX10 Ready), solves the problems without another "layer" of confusion for folks. So we can't recommend" what Steve is offering ... that would be stifling new ideas, and we are pretty keen on new ideas here. People just have to keep in mind, it is "their" computer and "their" system, Anyone can make suggestions on our forum ... that's what it is for ... for idea-sharing.
But if there is a problem now or later with P3D and the converted objects, we won't be able to help folks. We are not taking the chance of doing the conversions here at RTMM because if there is a future problem, it would really hurt the site. We don't know how the "migration tool" is going to work for P3D, etc. Until we know (and it will be soon I'm betting) we'll take the conservative option.
So forgive us for being conservative on this issue ... but until we can see the future clearly by look back, I just don't want to take any chances with the object libraries. This is not to say you should not use Steve's tool ... it is just saying its use is beyond RTMM's ability to help you technically if you encounter a problem. 90% of our objects are DX10 Ready, and therefore will work in P3D ... that is how we are getting ready for the transition. We just don't want to add any complications at this point.
