Sky VS NULL Created 12 years ago2011-09-15 09:19:18 UTC by Stojke

Question: Shouldn't sky be as good as/better than NULL texture?

Sky brushes are only meant to be used for exactly that. Bevel is much better than Null because it saves on clipnodes.

I rarely use BEVEL because it's very problematic. Some faces, especially curved can become non solid or you can just fell in the ground where it's a bit more complex geometry and so on. However, it can help in some places.

...Bevel always makes faces nonsolid. That's what it's supposed to do. It reduces clipnodes by making unneeded faces completely dissapear.
Just out of curiosity, do you use the clip texture?

That's no what I mean... I mean if you have a brush with some faces textured and some texture with BEVEL then those normal textured faces which shouldn't be non solid sometimes become non solid.

what an idiot...

Considering it was your bad wording that misled him, I don't think you're in a position to say that.

But ive done some testing with sky, and on some parts it generates less Wpoly than when i used NULL.

And bevel yeah i know about Bevel, but i avoid it when it comes to angles >90/180.

Also one more question:

How can i increase rendering distance of Hologram render mode (disort + fade)??

Methinks that's hardcoded

Yeah seems like it, thanks. If any one knows that its not, please tell.

I don't recommend using Sky textured brushes in replacement of NULL or BEVEL brushes. Simply because Sky brushes generate light and therefore RAD has to do lighting calculations on them which will increase your compile time.

Otherwise, yes, they work pretty much exactly the same. Use BEVEL wherever possible, but use NULL if you are having problems with a certain area or small objects or complicated brushes (like arches or other complex geometry).

Well, i've also noticed it fixes some light errors. I am thinking of exploring this a bit more, if i find a practical/good use i will make a forum thread.

Also, i don't worry about compile times, intel i5 compiles quite fast i have to say

What you mean exactly by light errors? Sounds interesting.

Some times when i used null, a texture that should have bit lit a little was pure black, but when i used sky it was lit the way it should be.
