T3D 1.1 Beta 2 - Detail texture size shouldn't be real small - LOGGED

T3D 1.1 beta 2

Windows 7 32bit

Target:
Detail Textures - Material Editor

Issue:
Detail textures normal maps won't use DDS DXT5_NM, but can use DXT1 (if you've applied the fix to this reported bug to get DXT5_NM working in general).

Repeat:
Make a detail texture and save as DXT1 - make a normal map for it and save as 2 seperate textures, one DXT1 and the other DXT5_NM. Boot up Torque and go to the material editor. Slap the detail texture on a material and then add the DXT5_NM for it's normal map ... nothing happens. Add the DXT1 normal map and see the nm applied as expected.

Suggest:
Fix DXT5_NM for detail maps

[EDIT]
Actually after saying all of that I'm wondering if it's down to texture size. I'd been testing with a x64 texture, and do see a considerable difference with x512s.

[DOUBLE EDIT]
NEW SUGGESTION:
Put in the docs not to use really small detail texture sizes ... title changed

I think that this is mostly my faux pas - but for some reason very small detail normal maps cause issues (64x64 against a x512 diffuse), in DTX5_NM not working at all, in DXT1 they just turn the material black in-game (depending on your strength setting in detail normal map).

It's probably not something to worry about ...
