Models for Games Notes (10/10/2012):

• Right click on the object and tick the box next to extrude. When the 'Extrude Polygons' window pops up select 'By Polygon' instead of 'Group' and choose the number you want in 'Height'. In this case I choose 4 (Ref 1).
• When mapping go onto 'Unwrap UVW' and select 'Open UV Editor'. When on it I then select 'Mapping' and choose 'Flatten Mapping' (Ref 3).
• If I am using UV Mapping / Editor then do not forget that 'Stitch Selected' will help connect the sides of a crate. But to do so I have to first break them (Ref 4).
• Using the 'Smudge' tool along with turning 'Normal' to 'Multiply' helped to make the blood look more realistic (Ref 7-9).
