triangle floor method Created 16 years ago2008-04-24 19:38:36 UTC by 12114

ive read a tutorial here on how to make realistic floors using triangles. ive tried and it was successful up to the vertex manipulation part, it went wrong after that. tried everything but still i get f'd up triangles (nowhere near what is i in the tutorial/what it should be). so can someone link me to another tutorial or explain it more thoroughly? :D. thanks

this is for realistic terrain im guessing.

you want to select all the triangles (wedges, really) and then using vertex manipulation, drag a square around a few pieces and pull in the Z direction (up) to raise and lower the parts of the triangles.

12114: please repeat your statement again. I don't understand it very much

No need to type it again.

Try reading the tutorial one more time, being sure to read each sentence and then not read the next until you understand and have done whatever it says. That was the tutorial I learned from, and if I could figure it out, anyone can.

I don't remember though, displacements have spoiled me.

A lot of the external terrain generator programs use this method. Actually, all of them. I recommend GenSurf but you can easily do it yourself if you have the patience. I do it this way.

1. Create a square cube.
2. Slice it from one corner to the other in the TOP view
3. Copy these two blocks to cover the area you want
4. I PREFER NOT TO USE VERTEX MANIPULATION
5. Skew the new triangle blocks up or down in the side views ONLY
6. Continue the process so that the edges align
7. use the BEVEL texture on all sides except the top to prevent bad clipnodes

Side views get tedious, because you always end up selecting the vertexes you don't want to mess with. Just go into 3d view and orient the camera so that its more or less perpendicular to your triangles and you should be good. Its not that senstive to camera orientation, but things get crazy when you're looking at it from a 45 degree angle.

You shouldn't link to Snarkpit here.

(People bite your head off, then rip you in half and feed you to their pet snarks!!!)

why use the triangle method when you have displacement surfaces. But I guess if you are mapping for half life 1 then you would still use this method. Vertex manipulation really isn't all that hard--you just need to be in the right view box. I have an old half life l map that uses triangles for the floors. Actually, it is floor, hills, and a little pond all using the triangle method. I will upload it if you would like. I will have to find it.

I posted a little simple map for you in the example maps. It's not much and it's really old so you'll have to re-texture it. I put a hl2 .vmf file in there as well. A little more updated but not much. Always use displacements for half life 2 as they will save on your overall render. Hope this helps.

Well it seems pretty obvious that he is mapping for Half Life 1, as this is posted in the Goldsrc forums...

wasn't paying attention.....sorry big guy.

lol
