Hello GDR1944, and welcome to RTMM.
Where did you see that written at? The libraries are in three parts, plus the tester scenery. It's not so hard to download three from the same page though, is it?
Nothing around here comes "bundled" except the Legacy Collection.
It's better to install each location individually. Then go visit it. It is the journey, not the destination that is stressed here.
readme1st Install Part I.txt:
The benefits of this new scenery library set are:
1. RTMM is now the single source for all of these library sets and will continue to maintain them.
The entire library set can be obtained in a single download.2. Many libraries have been added to expand our ever growing number of objects.
3. The textures in all of the libraries have been converted to .dds so that FSX DX10 users do not have to manually convert the textures for visibility.
3. The FS9 objects in these libraries have been converted to be FSX format so that our P3Dv2 users can now see all of the objects used by RTMM except as noted below.
4. In general, FSX objects will render a bit faster in FSX and P3D than FS9 objects so there may be a gain in frame rates.
I have all Payware required for complete install.
Thank You for fast reply
