Post-processing effects test (SSAO/HDR/Bloom)

[myconid]

The file shaders/effects/terrain_grass.xml seem to be missing from the commit, as well as terrain_triplanar.xml. The file art/terrains/grass/grass1_spring.xml references the terrain_base.xml material.

And they magically appear...

[zoot]

Now missing art/materials/terrain_grass.xml (last one, I hope).

[zoot]

Okay, got all files. When I start a match, I get this error:

That's what you get for trying code not meant for release.

Try messing with the number of passes in terrain_grass.xml. If you're lucky it might work even with the error, if you aren't then you'll just have to wait until I'm done with the terrain renderer implementation.

[myconid]

How about now?

[zoot]

No more errors, but the texture just shows as black:

I'll try playing around with number of layers etc.

Try pulling & recompiling now.

I can has more info plz? Was that supposed to be the grass texture or are other textures broken as well?

[zoot]

I happens on other textures too. This is one of the Oasis maps:

Also, Atlas segfaults when I attempt to start it.

Currently recompiling.

[zoot]

In the latest version, some terrains are black, but others are not.

This is Oasis 1:

This is your test map:

Can you name a map that uses grass1_spring? I thought the test map did, but on that it actually looks like its the snowy portions that are broken.

Celts Sandbox uses this grass (it's the default grass you get when you open Atlas).

Can you go in Atlas and test the "Snow/Snow Grass 2" terrain type? That really shouldn't be black. Maybe it's missing a texture or something like that? How about "Biome Alpine/Alpine Cliff"?

Here is Celts Sandbox:

Atlas has begun segfaulting sometime after I upgraded wxWidgets (though the Actor Editor worked when I tried yesterday):

Okay, downgraded wxWidgets. It's "Snow/Snow Grass 2" that's at fault:

I get no missing-texture errors.

I see nothing obvious in the code that could be causing that, so maybe you changed something in the xml? The cliff is using exactly the same effects/code as the snow material, and additionally uses triplanar as well. If the cliff is working, then the issue is probably with the xml somewhere. Make sure your local copy is exactly the same as on github.

Also, the grass material is half-working in your screenshot! The layer transparency is missing, so you don't see the layers below...

I've reset back to upstream/terrainmapping. I get this error now:

Cool! What would the transparency be missing? Can I fix it?

Give the latest commit a try. Maybe it'll help.

Grass is working

Still some issue with "snow grass 2", though.

[Mythos_Ruler]

That is just fantastic. This stuff seriously needs put into the game.

[zoot]

It isn't even all that slow in-game. Sure, the mouse pointer is a bit heavier, but this is a netbook. On a high-end system it could handily be an option. (Not that we shouldn't try to optimize it anyway, of course.)

Hmmmmm... Maybe something is up with the lighting? If you edit art/terrains/snow/snow grass 2.xml and remove the line with USE_NORMAL_MAP does it work? How about the one with specular?

It's a bit laggy on my laptop just by drawing a screen full of grass, though I'm sure a gaming PC can handle this effect with ease.

I have no such line in that file:
