I have a problem with the grass of the landscape textures not showing ingame. It shows the correct texture when I look at it on the Creation Kit, but when I load any cell or worldspace ingame the grass is all gone. I have tried many .ini tweaks but it does not seem to solve the problem. Anybody can help me or send me his .ini files to see if that is causing the problem?

Nevermind, fixed it using this tool to create Skyrim.ini and SkyrimPrefs.ini for me: http://online-source.net/tools/cfg-makers/skyrim-cfg-maker/

That is a nice tool, thanks for sharing.
