The CONTENTWATER tool texture removes collision from a brush and mirrors the brush faces inside out. It also marks the contents of a brush as water, allowing you to swim in it, but only if it's a world brush.Click here to check out an example map using CONTENTWATER by Windawz.

Useful Applications

Volumetric Lighting

Volumetric lighting can be textured with CONTENTWATER in order to make it look more realistic.

Conflicting Entities and Textures

CONTENTWATER shouldn't be used on world brushes or entities that don't produce a brush model, such as func_detail or func_group. Doing so will result in turning the object into a water volume that will cause visibility errors for whoever submerges themselves into it. It also conflicts with the following tool textures, resulting in a mixed face contents error:

• CLIP
• CLIPBEVEL
• CLIPBEVELBRUSH
• CLIPHULL1
• CLIPHULL2
• CLIPHULL3
• BOUNDINGBOX
• CONTENTEMPTY
• SKIP
• ORIGIN

The HINT and SOLIDHINT tool textures cause no errors, but they shouldn't be used with CONTENTWATER.
