5 brushes (totalling 30 sides) discarded from clipping hulls

See titles ^

Apparently the compiler is being a smart-ass and removing redundant clipping stuff. Don't worry about it, if the compiler does it it must be okay, right?

Well it's not so much being a "Smart-Ass" as it is just taking away irrelevant brushes from being clipped. This may also apply to func_illusionaries func_water and other walk-throughable brushes. I believe it also ignores clipping of brushes that a player would not be able to touch (Extra brushes that are out in the void). This is a normal message, and you'll always see it (for example my latest compile log had this amount -> "119 brushes (totalling 718 sides) discarded from clipping hulls") It's not an error. It's just a compile process.

It confuses a lot of us though, because prior to 2.5.3 or build 17 or something it never came up. At least, I think it never came up. When I started work on my NS Combat map it showed up once and I'd never seen it before. I was kind of scared that it would put holes in my floor that players could inadvertently fall out of the level or something... apparently that's not what it means though.

I'd think I would have more than 5. Its a huge map. But then again, I have no func_illusionary's in it.

Well it's 5 blocks, apparently. 5 brushes x 6 sides (block) = 30 sides. func_trains, func_conveyors (anything with a "not solid" flag) will also be removed from clipping hulls if that flag is checked. Definately not an error.

Ah, can't believe I forgot, but this should shed some light on why people are suddenly posting this as having never seen it before. Zoner's compile tools did not remove func_illusionary's from the clipping hulls. In other words, a func_illusioinary would increase the map's clip node count. It wasn't until Merl started making revisions on the tools that he spotted this and yoinked the illusionary's and any "not solid" entities out of the clipping process. Thus, this message would not have been a factor until you started using Merl's tools.

I started writing that post earlier CCS, but when I tried to put it in words I ended up confused as to why in the past they weren't removed from the clipping hulls - at what point in the compile did they stop blocking player movement then?
