ISSUES REMAINING: SKYBOX
I met rendroc on MTBS and he written a shader fix for shadows not using helix's wrapper but by editing the games pre existing shader library that is used each time game loads(instructions on how are in comments). The skybox/crosshair issue isn't that bad since crosshair is optional. Skybox isnt that a big of deal either and Id rate the game as great after fix which is a huge leap since it was unplayable before.
HOW TO INSTALL:
Launch the game all the way till you are able to control your character.
Exit out then navigate to ../Documents/My Games/Velvet Assassin/
Delete the folder labeled SHADER
Navigate to ../Velvet Assassin/shader/
Paste world_rtsm_pass.fx inside then replace.
