Mapping N00b Needs Help With Ramps

Soul_Rider

I am creating a map and in the centre is a room with sloping walkways to get up to the next level. I used vertex manipulation to create the slope, now i get error messages when compiling saying the brushes for the ramps are out of the world. Obviously they are not according to what i have done, but how do i stop this message and correct the problem.

This is my first map, i am a T0tal N00b, so please keep your answers simple, thorough and totally n00b proof, thank you.

with so little information i dont really kno, best idea i can come up with, is that uve turned ur brush inside out, if u havent or ur not sure, just delete it and remake it, if its only a ramp, it shudnt be difficult

in one of the boxed windows, that is not a camera, zoom out as far as u can to see if and blocks or any thing is outside of the big square ( square with a bunch of littler squares )

Dont worry i have just started mapping less than a week ago so im pretty much winging it <!--emo&::asrifle::--><img src='http://www.unknownworlds.com/forums/html//emoticons/asrifle.gif' border='0' style='vertical-align:middle' alt='asrifle.gif' /><!--endemo-->

Probably an invalid brush, a brush in the haf-life engine has to be convex, Meaning that it isnt possible to have a shapechange along a face. A face has to be flat. The brush also can't be caving in on itself:

Ascii example, top/side view of a brush(the red part isnt allowed):

/    <span style='color:red'>\/</span>   \
\_____/

Use ALT+P to let Hammer check for problems. The best thing to do if you're not sure on how to fix it, do what <b>Kester</b> said (delete and rebuild)

<b>Not recommended:</b>
Another thing you can try to let Hammer fix it. Hammer will most likely deform the brush so it doesnt fit into your architecture <!--emo&:p--><img src='http://www.natural-selection.org/forums/html//emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif' /><!--endemo--> But on very few occastions it usefull to let Hammer do this, nowyou can manually vertex manipulate it so it is a valid brush.

When doing some vertex manipulation keep the thing about convex brushes in mind.

Kester

u can of course, make very complex brushes that is only one brush by using vertex manipulation, but its not really for the faint hearted or anyone thats new to mapping

when making wierd shapes... always remember that triangular faces are often much easier to use and inherently more flexable than their square counterparts.

errrr? all i did was this:
1. Create box - ______
------------------|_____|
2. press enter to create brush

3. reduce brush to flat line ______

4. use vertex manipulation to lower front edge

5. and voila, my brush is completed. That was all, no complex shapes, nothing tricky, just a ramp. As i said, this is well inside the map, about as central as you can get in all direction, left, right, up and down.

Does that explain it any better?

And according to hammer, there are no problems. This is only happening when compiling.

PLease also note the dashes in above diagrams are only to hold the other lines in place in the forum!!!

u cant have a flat brush, it needs to have some mass try making it 4 units deep (looks good for grate textures) to make it look realistic (mebe even more depending which texture ur using)

Kester

but it u do only want to be able to see it like a flat line, dont make it a flat line, just texture all faces apart from the top one with null
