PR Beta 5

Beta 5 is now available on the FTP. Here are a list of changes: - Fixed full screen ALT-Tab bug - Added toggle to allow underground movement in LStudio - Enabled D3D pipeline for cards without T&L (new terrain engine and BSP renderer should work on all cards now) - Added support for Vertex shaders. Use PRO Edit to include your shader code and define the constants you need (not fully completed or tested, don''t use until next release) - Added support for characters within LStudio - Fixed bug when using LStudio texture generator more than once per run - Added support for BSP only levels in LStudio - Add support in skeletal system/biped exporter for multiple segmented characters. This means the old weights.dat file from your characters will be invalid and you''ll need to export them again. - Added DirectMusic support (prdmusic.h). Changed LStudio to use generic "song name" in level properties. It now supports .MP3, .MID, and .SGT. - Fixed viewport size bug in CHR Edit - Fixed a few more bugs in the BSP shaders, and collision detection.
