Any way to stop Darkradiant from causing this?

[AluminumHaste]

I built this railing on grid size 1, all vertex points align to grid, all textures line up and are to same scale.

When I go into Darkmod and DMAP, I get this weirdness with texture stretching:

 

 

There's weird triangulation going on also:

 

[VanishedOne]

Output from r_showTris might help work out what's going on. My guess would be something to do with patch subdivisions and/or how your detail work is/isn't divided into func_statics.

[Bikerdude]

Yes you place a brush in the same plane as the patch, then copy and past from face of the brush to the patch!

[AluminumHaste]

It's all func_statics. Also patch subdivisions manually set to 4 and 4.

@biker, that's how I have always textured patches especially bevelled end caps.

[Bikerdude]

Your gonna have to do that for every face - its a DR bug,

[Spooks]

You can also try and export the railing to an ase with the script, I don't know if it'd help but it may be worth a try to see if it's dmap doing it, if it looks fine in DR.

[AluminumHaste]

That's what I did, but now when I just went into DR, it's all back to what it was before.

Okay fixed it, and now the textures are correct. However now the triangulation issues are back. Now all sides of the railing look like the second screenshot.

I guess Doom3's engine just can't handle optimizing faces at such a small scale. Oh well, will scrap the railing.

[nbohr1more]

You could always make a custom material def with the "discrete" keyword in the material def to prevent Doom 3 from messing with the triangulation.

[VanishedOne]

The scale might be less of a problem than if it's generating thin 'sliver' triangles.

 

 

Bottom right is what you get when all the brush- and patchwork belongs to the same entity; top right is how it looks normally in the game, with ugly spark lines. Bottom left is the manually optimised version seen in DR in the top left, where the selected bits are their own func_static.

I could try that, making the separate parts func_statics.

[AluminumHaste]

Okay I scraped the railing and started over, much nicer design now. However, I'm still getting horrible results.

Here's it in DarkRadiant showing the separate groups:

 

 

There's 2 patch groups, the cross shaped circles are actually 2 separate groups. And the smaller arches near the bottom are separate groups.

The geometry is part of it's own group.

 

In game it looks like this:

 

[Bikerdude]

You will export the small fiddly bits as .ASE models to fix the above sparkles/lines issue.

[VanishedOne]

It might be worth seeing whether you've more patch subdivisions than you need, as in this case:

 

 

If that doesn't help, feel free to post a prefab to examine.

[AluminumHaste]

For the patches I've tried 4x2 and 8x4 subdivisions, doesn't make a difference.

 

Here's the map.

.ASE is much better, but on my intel GPU I am seeing small lines which I would say to ignore..

 

 

 

[AluminumHaste]

Damn, even with ASE it's still not perfect.

[Bikerdude]

I did say that my GPU is intel, try with an Ati/nVidia and I would think the lines would not be visible.

 

The thing to try is import the .ase file into blender, do a simple cleanup and export.

[VanishedOne]

 

I got the westernmost section to look like that (the one on the right is unchanged, for comparison), but I had to reduce the patch detail in order to do it.

 

AMD GPU, by the way.

Have you tried recreating this shape purely out of brushes? I imagine that would eliminate the artifacts and you wouldn't sacrifice much detail.

[AluminumHaste]

yes it would be brushes would not be able to have smooth curves.

[Bikerdude]

you can, you makde side from brush and the inner from a patch - I will make a an FS for you.

[rich_is_bored]

This isn't bad is it?

 

[AluminumHaste]

No it's not bad at all.
