VisPatch 1.2 by Andy Bay
VisPatch lets you extract/import the VIS data of Classic Quake levels (BSP29).<br>
It was created to provide an easy way to prepare existing levels for transparent water:<br>
Someone re-vises an existing level for transparent water, which can take hours, extracts the new VIS data and makes it available for download.
Others can put the new VIS data in copy of the level, so they have transparent water in seconds.<br>
