Occluders & Hints

soylent robot · Aug 22, 2009

I'm optimising my map, but before I really start I have some questions about occluders & hint brushes:

Will occluders work if all sides of the brush have the occluder texture, or do some have to be skip textures?

Is it a good idea to put occluders in every building wall in my map?

Will bad things happen if I turn all my level geometry into func_detail and just use hint brushes to control the visleafs?

1. yes they will, except you use nodraw, not skip
2. no
3. Just a gigantic leak. Why'd you do that anyway, to increase the filesize?

I'd recommend you fully understand optimization before messing with hints, occluders, or any other optimization brushes or entities.

I haven't used occluders yet, but this tutorial seems to explain them pretty comprehensively.

The tutorial said:
extreme overuse of occluders in a single area/perspective will actually increase how much info is being processed by your computer resulting in lag/fps loss

So probably not, if the walls are close together.

I don't know why you would want to make everything func_detail, vvis should take care of walls etc. that obviously block the player's view.
