modify .mat files and blood stain help

[Kreekakon]

Here's a much easier way for you to use only one of the four images in decals like "blood_smear_01.mat". In the decal settings you should see a setting which says UV SubDivisions. Set that to "2x2", and the UseSubDiv setting next to it to "Random".

The decal you are using should now randomly choose one of the four images when you place it.
