World of Tanks Map format.

BTW....
In opengl.. GLSL... when you try to use a texture that has nothing bound to it, it will return unexpected results.

Do this also...
you must create a dummy texture the same size as the layer textures.
If there is NO layer for say... number 4.. use this dummy and bind it to that texture position.
This is why I have a variable I save called layer_count.
When I do the reading of the layer files.. I update this variable.
You can also use this variable in the shader if you need it for some reason.
I found adding an empty texture had no effect on the overall mix as long as RGBA = 0 0 0 0

Also.. your mix texture should be set to RGBA = 0 0 0 0 when you first create it.
I use Devil and it works well for creating empty textures. I dont know if you can use it

[Coffee]

So just scale the texture to the chunk size? But how to use the color_tex then ... I can't scale i to chunk size, color_tex must cover entire map.
Do I need to treat the color_tex differently than rest of the textures? If so, is there any other way to identify color_tex other than it being the first layer?
Currently I just use the color_tex as background and then apply the other layers, which works and looks nice, but somehow I feel this isn't the right way

See.. This is a huge issue I had.. The color_Tex can wind up in layer 1 to 4.
The only way to know is to check the string and see if it matches.
The thing is... It doesn't seem to matter as far as the final mix.

To deal with the size( 4096 x 4096) you can scale the UV coords for the other textures
If the map is say... 12 x 12 chunks...
pass the map location in X,Y to the shader along with the size.. in this case 12.
Now... to scale it take U and divide it by the map size (12) and add (1.0/12.0) * location X
You would do the same for V.
Use these new UV coords in the shader to look up the color_tex RGBA

[Coffee]

What I actually did was to cut up the color_tex in to a bunch of smaller textures.
It works but is slow and scaling a UV for it is a better solution.

[SkaceKachna]

I actually use one big texture, containing all chunks in one image, composed using image operations only (no 3D, GL etc) (it's better solution if you're loading images using browser, loading 144 images would take much more time)

Thanks for providing more insight

[Coffee]

no problem...

Actually...
there are usually 4 images per chunk so for a 12 x 12 map that's 144 *4 plus the low rez map and its normal data.
Loading the texture is by far the slowest part of my app.
Even loading the models is a pain.
But.. I reuse any textures already loaded.. so this saves a lot.

[Coffee]

Currently I just use the color_tex as background and then apply the other layers, which works and looks nice, but somehow I feel this isn't the right way

There is nothing wrong with this...
As long as you are actually using the mix values. If not.. it wont even be close to the game's terrain.
Also.. there are the UV transforms that need to be done.. This could be done before applying them to the main texture.

I get an error with Terra though. Clean full HD install of WoT.
I want to select the map Abby and then:

Probably because it cant find the lighting settings file..

I'll be updating a new version soon.

[Coffee]

Well....
It took for god damn ever but I managed to figure out how to project the decal textures.

I'm doing it with the CPU so its not real fast creating the meshes. I may look in to finding a way to do it using a shader or I might even save the meshes and export them..


In this Image you can see the decals mesh deformed to fit the terrain. Its made of a 32 x 32 cell mesh.


In this image, I have turned on solid fill, blend and added the decal texture.


Now The terrain is rendered as usual along with the new decals.


Buildings and trees turn on.


I had already wrote a function to find the Y point anywhere on the terrain's mesh..
I found out that it had a very BAD bug and it took me the better part of a day to find it.
Integers cant hold floating real numbers.. DUH!!!!

I have not verified the textures are not flipped..
I was so excited to share this I didn't take the time.. LOL!!!

EDIT: Yep.. Textures were flipped on V... All fixed now

[Coffee]

I get an error with Terra though. Clean full HD install of WoT.
I want to select the map Abby and then:

I found the problem..
I left a write to the hard drive in the app.. It was for debugging and never took it out..
Sorry

[SkaceKachna]

Wow, really good job. It looks like ingame now!

Yeah, I figured it was a hard-coded path left somewhere.
Is the new version up for download? I'll host it at Xentax as well if you like.

[Coffee]

I will update in a bit..
I have some clean up to do first.

A temp work around is to create these folders.
"C:\!!_ENSK\BWSG_DUMP\"

It was used to export all the vertex chunks when I was sorting that out.

[Coffee]

Wow, really good job. It looks like ingame now!

Thanks

Now I need the shadows.

[Coffee]

I am having real issues with the decals that over lap fighting the Z-buffer..

Does anyone an idea how to solve this?

I tried turning off depth testing but that causes more problems.

EDIT: I'm working on a shader for the decals... They need a lot more bump mapping!
