Why bother working at the full res when dealing with such big resolutions? Work at 25% of the resolution and once ur done rerender the maps at full res!
No. UDK is free then takes 25% after your first $50,000. This is a pretty reasonable deal if you're not crowdfunding and not expecting to make more than one product.
Had a great weekend with family, turning 25 this wednesday, then a big BBQ with friends on friday. I'll be feeling good with some gooood drinks in me haha!!
I made a short image tutorial for cutting basic holes into meshes. Maybe it will help. http://seanvangorder.wordpress.com/2010/10/25/tutorial-cutting-holes-into-meshes/
