Unlike other free game modification utilities, the XSI EXP for Half-Life 2 gives full access to all the professional features available in SOFTIMAGEXSI. Everything you need to create Half-Life 2 characters, models, and environment elements is here.

You can design characters, mix and blend animations, render interactively or use real-time shaders, and then export your models to Half-Life 2.
