UDK: Unreal Developers Kit
UDK is here. With it come a huge ammount of improvements, everywhere from SSAO (screen space ambient occlusion) Dynamic interactive water, vertex painting for indevidual objects, Global illumination, Emmisive lighting, the new speed tree 5. The aditions are great, but can be rather daunting, Thankfully Epic has provided a web page with a list of improvements and links to descriptions and tutorials for these new features.
Everything on this web page is worth reading over. In time, i will be adding to my tutorials including many of these functions.
If you do not already have this but wish to download it, the web site is linked below.
Happy creating everyone, i hope you enjoy the new unreal.
