Degenerate Triangle? Created 18 years ago2006-04-08 14:19:53 UTC by Exos

When ever I compile the map I am making, it says "Degenerate Triangle" along with a few coordinates, but it says it ALOT, it makes my compile log huge. What is a "Degenerate Triangle?"

Please post the whole compile notes so I can pin point it out...

Usually errors like that = bad mapping where brushes mix or you apply func_detail to the wrong things.

Okay but this compile log is huge.

Dude, your map has HUGE problems. This is usually caused by tiny micro brushes (less than 1 unit big). Only way to get rid of them is to find them and delete them. I sorry to say, you may have to delete everything to get them all. QuArK has a built in micro brush finder. Hammer might be able to find them with check for problems (ALT-P).

Do not use carve for anything but square brushes, that's a major cause for this. If you don't get them all, things are going to work odd. Brushes may be black, some brushes may go on forever in a certain direction ect.

If you post this map in the problem maps area, I'd be glad to run it through a micro brush finder.

I try not to make noob mistakes like overlapping, getting things off the grid stuff like that. I never carve or hollow. I am just going to not continue on this map.

DarkKilauea: Are you sure?
My map has this "error" in it, and I didn't have it until after I put in displacements in my map.
And the more I have the more Defenerate Triangle thingies I get.

I think it's just simply the compilers way to express the different movments of the displacements wich after all is, builded up by triangels.

Degenerate Triangle
(-1607.54, -2253.00, [m]224.63[/m]), (-1607.54, -2253.00, [m]224.63[/m]), (-1607.30, -2253.00, 225.31)

Two points of the triangle are at the same point in space. That, uh, makes a line, not a triangle.

It sounded like a displacement thing to me at the beginning, and if Madcow says he only got it when he smacked in a displacement, I'd guess that it's some dodgy, er, displacing.

You wanna touch it?

No seriously, I can post it, nothing odd with it, just a field of grass smoothly manipulated.

Ive only ever found this with displacements, it gives you coords so go there and fix it!

Either that or the compiler is calling you a degenerate on society

The problem is not that serious.
If the map starts lagging, THEN you might wanna fix it, else, nah.
(IF it is an error)

A triangle with two corners sounds pretty odd to me :).

im sure some mathematician has created a dodecahedron with 3 faces because it obeys the laws of johnsons last whogivesashitheorem

that's imposseble to do in hammer though.
I'll try to make a normal displacement and check the compile log and see what happens................................tomorrow

I found degenerate triangles to do strange things in any of the maps I've created. Of course, this was for a non-source engine, but the basic principal applies. If it's with displacements it might be ok, but degenerate triangles or faces on world geometry is really bad. I'd still fix it, cuz either way, your wasting polys
