[LVL ED] "Planes" doesn't save correctly using custom material in the "Level Editor"

[The chaser]

Make sure your texture (not your material) is in your Amnesia folder, like:

'C:/Program Files (x86)/Amnesia - The Dark Descent/redist/custom_stories/BigG2k TEST1/textures/Background.mat

And, inside this folder, to have the .dds. Remain to make it so that Background01.mat points out to your texture.
