GLDEFS Issues

[Dave_B]

Not too long ago I released a deathmatch WAD which incorporates textures that are set to glow by the internal GLDEFS lump. On earlier versions of GZDoom this seems to work fine, but in versions 1.1.05+ this no longer works, and as a result some maps have been ruined by this 'glitch'. Anybody having similar problems with their WADs?

The glow implementation has changed for 1.1.05. It now uses shaders because the old implementation had serious problems.

However, since shaders are only available on modern cards they are disabled by default. On older Geforce cards, for example (like GF6800) shaders exist but come with quite heavy performance impact.

As a result I chose to make all shader based features inactive by default. You have to explicitly enable them in the options menu.

Do the glows now also work on slopes?

Yes. That was the whole point of this change.
