• Hollow Spheres?

Hello! Just a quick question, are hollow spheres possible in Hammer? When I created a sphere, and used the Make Hollow tool, I ended up with this abomination. [IMG]http://i.imgur.com/h1WpRaB.png[/IMG]
face edges must meet, hollow overlaps them. [editline]28th April 2014[/editline] Oh, those aren't displacement faces... Good lord man.
Make a model.
What I would do is first make a sphere, then make another from scratch with the cut/divide and vertex tool using the first one as a guide, delete the first one and copy paste the 2nd one. Then I would "make hollow" the new third one, and use that as a guide to make a 4th final one out of multiple brushes by hand using the 3rd as a reference. But a model sounds easier and more optimized
Make two spheres with the sphere brush tool, a smaller one at the center of the other. Then carve. Watch your computer explode in seconds. :v: Just joking, a model will be a a nice option, as onebit said.
The only non model solution I can see is subdividing inward-facing displacement faces, but that won't be a perfect sphere.
If you're not going to do a model, you can use [URL="http://www.users.on.net/~imperialcarp/Twister/Twister.html"]Twister[/URL] to generate displacements like this. I think it can do sphere interiors.
Simplest way,even though it's not a perfect sphere: [URL=http://cubeupload.com/im/L9cf44.jpg][IMG]http://i.cubeupload.com/L9cf44.jpg[/IMG][/URL]
I made a map just out of boredom which was enclosed in a hollow sphere, the process involved making a sphere with the max amount of indicies and then hollowed it [B]inwards[/B] for i think was about 16 units so it wasn't a negative number, there were alt+p errors which i had to fix but I didn't notice a difference, here is a picture of that map, i've made it a playable map but haven't yet released it on my workshop.

It's not really hard to make parabolas and spheres, it just takes a long time and is pretty impractical since it eats tons of brushes. [img]http://i.imgur.com/BwcCpc9.jpg[/img] Using a model makes more sense, though getting a perfect collision hull for it would be a monumental pain in the ass, not to mention be expensive to interact with in the engine.
I remember making a sphere map once to see how many times I could get the crossbow bolt to bounce, turns out it was quite a lot. Just used the sphere preset on brush tool and make hollow, which fucked it a bit but it still functioned as a hollow sphere.
Oh yeah, I forgot I'd already made something like this a while ago: [url]https://www.youtube.com/watch?v=uAAIpkTU5e8&t=1m[/url] [T]https://dl.dropboxusercontent.com/u/17850283/dome_fix0001.jpg[/T] If you're too lazy to do it yourself, [URL="https://dl.dropboxusercontent.com/u/17850283/dome_fix.vmf"]here's the map[/URL]. Just dupe the gray dome bit three more times and put the pieces into place, then scale them.
If I'm not mistaken, can't the Torus tool be altered to create a shape like that?
Yeah, it can.
[QUOTE=Mozartkugeln;44700132]Yeah, it can.[/QUOTE] In that case, hollow spheres aren't as bad as they seem. :v:
[QUOTE=Mozartkugeln;44700132]Yeah, it can.[/QUOTE] Not in Hammer though. :v: Here, have a hollow sphere: [URL="https://www.dropbox.com/s/zw4y51tcafajloq/sphere.rmf"]sphere.rmf[/URL] 2048×2048×2048, wall width 64, as per the OP. 32 sides, 1024 brushes total, all verts on grid. Done with Sledge. Yes, it's an RMF, Sledge and VMFs don't get along all that well. Just change the file type to "Worldcraft RMFs (*.rmf)" when opening the file in Hammer.
Your best option is the Torus tool, indeed. Either you can use Twister or make it a displacement.
