-meta seems to be messing up my terrain?

(rgoer) #1

I’ve got a terrain entity–brushwork, .pcx alphamap and .shader file all generated by EasyGen–that seems to get mangled by -meta. Here’s how the terrain looks in ET (this is just BSP -meta, no VIS, no light):

Here’s how this looks in Radiant:

The shaders in my terrain shader file follow this template:

textures/rc_ville_terrain/terrain_0
{
	surfaceparm gravelsteps
	qer_editorimage textures/rc_ville/rock_t03.jpg //for radiosity
	{
		map textures/rc_ville/rock_t03.jpg
		tcMod scale 0.0500 0.0500 //this is going to be tcGen vector stuff, but I haven't gotten around to changing it yet
	}
	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
	}
}

I’ve used these exact same shaders on a different terrain and never seen this kind of weird behavior before. Any help with this situation would be much appreciated.

Recreate the brush manually? Brush cleanup?

Nice icon. :slight_smile:

Sometimes large continuous flat areas like that screw up. Vertex edit them to be a little jittered, and the problem should go away. I’m not sure what causes it exactly.

Anyway, you should bring your shaders up to spec (using q3map_baseshader and q3map_tcGen ivector).

:moo: thanks, I love me some Ico.

In any case, I’ve gone in and mussed up some of the flatter areas, and I still seem to be getting these goofy triangles. Their location on the terrain mesh fluctuates between compiles, too, I noticed–two compiles give two different sets of borked tris.

The other thing is: you mentioned “large continuous flat areas”–the triangles that make up my terrain aren’t particularly large–256 game units on the square side (~362 units hypotenuse). I know you mentioned that this behavior seems to be a bit random, but is there anything else you could think of that I might try?

Oh, and by the way: that Ishii map is pretty damned tight! A bit easy to camp on the railgun, but hey ;^) a thing of beauty nonetheless.

i had this “earthquake” effect also when creating terrain. i found out that creating smaller triangles(more subdivisions) or decreasing size of the terrain helps

if the triagles are near to flat they somtimes do this.
try to raise them a bit like if you want to make a small hill “v” or “e”.

or build a house on this place. :smiley:

I’ve had this problem too.

Terrain sucks, basically. (It’s a replacement for gravity…)
