Distant Terrain Button

Where is this button? Derek stated the following in one of his posts about the new TS2012 features:

Distant terrain setup

Setup
There is a 20km area of mid distance terrain, this should be generated as a bare minimum around the track to avoid the world edges being visible.

To import ASTER GDEM data the old ‘T’ key has been replaced with a new dialogue accessed from a button in the paint tools tab. The area option controls the amount of data, the data type allows a choice of SRTM and ASTER data sources.
Aster data is available on the web as .tif files.

Very distant terrain may also be generated using the distant terrain button, this generate very low res 4km x 4km patches from the height field data, this is saved to the file DistantPatches.bin.
Usage
To import terrain use the import terrain button up to 19 x 19km squares can be imported at once.

To generate distant terrain patches, import terrain for all required areas, then while in tile 0,0 use the generate distant terrain button to build distant terrain patches. Save (F2) after generation.
Performance Constraints
Distant patches have some overhead and should only be used as required.

The "bolding" is by me but does this actually exist and if so where?

I used it the day RW3 came out and it worked, however apparently many people experienced problems. I believe it was taken out so that these bugs could be fixed.
