Mostly, matrix is fine but how to get more then one 256x256 image for all the tiles? I mean it's only like 4 128x128 tiles

hows about a 1024x1024 image? Then you can divide this into 256x256 images.

But it says in help that for matrix, texture can't be more then 256x256..

And also, 4 images it's nothing, if you need to create landscape.. with different types of grass/sand/water/ice/rocks/roads etc..

How about BSP? What you can do with that? Are they faster then matrix or regular objects?

BSP files are also limited in size but they may not prove useful for large terrains, BSP files are really used for indoor locations to cut down on Polygon counts. Large exterior locations will still prove inefficient for BSP files.

BSPs are for room/indoor type terrain rather than outside.

Have you tried using more than a 256x256? It may work depending on your Graphics card. Also you can have more than 4 tiles (my current on has 16). Remember that the texture is applied per square of the matrix, so if you keep your tile size to something sensible you can get away with lower res textures. And hopefully your matrx will be covered in lots of objects to hide the floor anyhow!

well maybe 512x512s would be a better starting point

Err, I thought you were talking about the matrix size but in any case, I think Magic World had some Monster Matrix utility which made enormous matrix's... they truly were large.

Why not have an image that is 1024 * 1024 which is actually 16 different textures (4 * 4) at 256 pixels by 256 pixels.

like this:

01 02 03 04
05 06 07 08
09 10 11 12
13 14 15 16

Even if EACH texture is limited to 256*256, the big image that the textures are cut out of can be massive.

Or...

Make a few little 128x128 textures, one for sand, one for grass, one for rock etc. Then use VANtrans to make 4 seperate transition textures and stick them together in an art package. That would give you a 1024x1024 matrix texture, which contains 64 different tile textures. This is a very similar approach to what Dead Glory has done with TML, and 128x128 is a reasonably nice resolution. You'd need to make a texture editor though, so you could select which tile texture goes on which matrix tile, no biggie though.

I was thinking that texture file itself can't be larger then 256?

What's Magic world?

I need two things first more textures.. I probably will go with 256x256 tiles in 1024x1024 texture or even 2048.

Then I need huge matrix so I can pan over it and don't see matrix end..

I'm thinking of using one 30x30 matrix with size of 900,000 camera will be in the center, then I'll try to use small 2000x2000 30x30 matrix just in front of camera to create some kind of LOD on the fly..

i started this:

http://www.darkbasicpro.com/apollo/view.php?t=4348&b=8

a while ago i made it using a 4096x4096 image tiled into smaller pieces and mapped to each tile. This might need the images flipping now due to a bug fix. (old code )

One trick that seems to work for me is using 4 matrixs each 1000x1000 in size with each one having 100x100 grids. I then slice my large picture 1056x1056 into 200x200 tiles and work out the spacing to apply on all four matrix. I've tried as high as 7x7 matirx the same size but of course it gets real slow...

I think real, unlimited size and texture, LOD terrain would be very nice addition to DB Pro
