Displacement maps Created 19 years ago2005-07-08 04:14:20 UTC by pepper

Somewhere i read that displacement maps dont block vis, if they dont, whay am i then able to compile my maps with vis and rad? And i also read that if water goes through a displacement map it wont show up. I do not know the reliability of these sources but is this treu, and if so how should i work around it then?

They don't, so assuming there's a big box around the level, cordon is on, or NODRAW brushes are properly placed behind them, it compiles. If the NODRAW brushes aren't present, it ends up like a giant box. VALVe used a skybox in d2_coast_12, the displacements just block stuff with occluders and hints.

Water should work if it goes thru a displacement map but you might experience some issues with swap buffers.

So what your saying is that if i make a displacement map of the top of a brush i need to put a brush with nodraw behind it?

Yeah, because they're not solid in terms of BSP.

Oh crap, half of the map is made out of displacements.

Wich idiot designed this system....

Would it be ok if i'd put a box around my map with no draw texture on it? Or would it cause problems?

Offcourse i would need to skybaox my map on the normal way.

You'd better put the nodraw brushes only under the displacement surfaces. Making a big box will increase compile times!

It will increase compile times greatly, but sometimes it's a necessity. bms_c2a5 utilizes a big skybox. (So does d2_coast_12 before any more people go OMGSKYBOXBAD!!!!11!).

Then again, VALVe has a renderfarm =<

Im not in the mood of spending all the time to putting nodraw textures behind something. But theres no way around then
