Ok, great news my friends !
Here is the pack : It's still not complete (desert trees, flames, and other details).
But it already enables you to play in HD with great graphics and terrain textures !http://www.timsoret.com/out/lugaru/textureshd.zip
It works great with new campaigns, they are now even more impressive !
Just replace the Lugaru data folder named "textures" by this one (make a copy before).
Of course you can use it as a base for Lugaru 1.5.
This pack was made possible thanks to the great cgtextures.com
About 12 hours of work.
I'll make a new thread for the final release, maybe with a video trailer.
