Troubleshooting Level Design

Please add to this document when you encounter solutions to problems you have encountered.

Trouble with Compiling Maps

Compiling the map takes a very long time

If your map is large or complicated, make sure you are using func_detail appropriately. See Controlling Geometry Visibility and Compile Times.

The compile window says there is a memleak.

Don't worry; this is not an error. Carry on.

Trouble with Lighting

The map looks super bright

You probably have a leak. See Leaks Explained.

Trouble with Props

Invisible Prop

The prop may have its fadeout distance set too close.

Also, some props can only be used as certain types of props and otherwise will be invisible. For instance there are tables that only work as prop_physics, and other props that only work as prop_dyanamics.

Trouble with Other Entities

A ladder isn't working

Make sure the ladder entity is not touching anything solid. It must be at least one unit away from all solid surfaces. Read the instructions carefully. Ladders work differently in Half-Life 2 and in Counter-Strike: Source.

Trouble with Counter-Strike:Source Maps

The hostages won't move

Hostages require a navigation mesh in order to work. (They used to use info_nodes, but that is now obsolete.)
