Black/Multicolour Textures issue
Updated: This proceedure should also work if you have multicolour textures as well.
Applicable Versions: TS2009,TS2010, TS12
The best way of dealing with this issue is:
Disabling the Hardware Compression
1.Open Content Manager.
2.Click File, then Settings.
3.Click Miscellaneous.
You should have a box looking the same or similar to this:
4.Click in the box labelled 'enable hardware accelerated texture compression' (highlighted with a red box in the screenshot above), to remove the tick.
5.Click Save.
Repairing the assets
To repair the assets:
1.Search for Location:Local, Built-In=false (see the image below)
2.Right click in the results list and click Select All.
3. Right-click in the results list and click Open for Edit (this is in the Edit submenu).
4.Right-click the results list again, then select Edit followed by Commit.
An alternative to steps 3 and 4 is to delete the affected content and redownload it. This must be done if you are using the content for Multiplayer in TS2010 SP4 or TS12.
