Texture shadows

Texture shadows in Portal 2

Texture shadows allow transparent model surfaces (not brushes or displacements!) to cast baked lightmap shadows.

To enable texture shadows, add -TextureShadows to the VRAD parameters.

Models

In QC

Add $casttextureshadows to the model's QC file to enable texture shadows.

Example:

$modelname "props_grate/metal_grate_64.mdl"
$model body "metal_grate_64.smd"
$staticprop

$cdmaterials "metal/"

$surfaceprop "metal"
$contents "grate"

$casttextureshadows

lights.rad

Textureshadows can be enabled on any prop without editing and recompiling the QC through the lights.rad file

Example

forcetextureshadow props_underground/walkway_128a.mdl
forcetextureshadow props_underground/walkway_128b.mdl
