Until then can we not make it so we could allow multiple versions of a map that are functionally equivilant but have different numbers of layers?

e..g we could mark a set of layers as non-important, and thus they-ll get rendered on faster machines, without leaving lower end machines out in the cold, or machines under heavy stress.

I'm thinking of a new terrain texture quality slider, filtering out layers the mappers flagged as unimportant , and downsampling textures

I highly disagree.
The load isnt all that big, and my 3 year old gfx card has no trouble running it on high quality.

Would everyone please do me a favor and test the map I uploaded? It uses 5 2k*2k textures in 4 blend operations (also 2k*2k blendmaps).

I used it yesterday while testing, got 20-30 FPS on my 9300M IIRC.

using tilesize=16 for grass stuff it looks even nicer, can't do the same for rock or you see the tiles when zooming out, would need more rock mixing like you did for grass to hide them, and yes the bumpmapping is not working

anyway good job !

i like this (AFs) suggestion, though i have no idea about all this stuff, if it was possible, how difficult and what not.. but sounds nice :D

Runs fine ~400fps.

Btw, your blendmap res is way to high.
Isn't the whole point of SM3 to save texture memory to allow larger maps?
I reduced them to 256x256, which gives the same result ingame. (I think)

Question: Are SM3 maps still required to be square?

Did some tests with less layers and lower levels of details, set to 1024 textures, improvements were very low.

Still around 100 fps, high terrain detail and shadows added as well.

Also, I tried DDS, but it shows up as black :(

frostregen.darkstars.co.uk/sm3_testmap.sd7

It's your map with 256x256 blendmaps,
textures still 2048 but converted to jpg,
and tilesize 32 for grass.

This moves filesize to 8,5mb with little quality difference.

almost the same except for the flow which shouldn't be resized that much

Flow had not been resized?

Code:
      [trocks]
      {
         File=Maps/res/rocks+det.jpg;
         TileSize=50;
      }
   
      [bgrass1]
      {
         File=Maps/res/bgrass1+det.jpg;
         TileSize=32;
      }      
   
      [ggrass1]
      {
         File=Maps/res/ggrass1+det.jpg;
         TileSize=32;
      }

      [bgrass2]
      {
         File=Maps/res/bgrass2+det.jpg;
         TileSize=32;
      }
      
      [flow]
      {
         File=Maps/res/flow+det.jpg;
         TileSize=50;

Try that test map I posted, I would like confirmation that it's DDS.

And I tested yours- it's a lot smaller than mine, but performance was worse- 25-30 FPS vs 30-40.

I'll take a look at the "size of blendmap" optimization, that sounds like a useful idea.

Heightmaps must be powers of two. So either you have 512 (8X8) or you must use 16X16.

Not real happy about that, it's going to mean a lot of workarounds, to get the sizes I actually want.

why does it have to be a power of two ?

It just does, apparently. Crashed and told me to use nearest power-of-two.

More irritating is that I can't use a double-resolution heightmap, or have it just read RAW correctly, so the resulting heightmaps aren't that great.

Did you try png 16 bit gray? (no idea if it works)

No, but PNG with alpha made Spring crash, not holding my breath on that.

You're fast...
just tested it. works flawlessly :)
Even using 16bit of detail, as far as i can tell.

Btw, why alpha for a heightmap?
PNG supports 16bit grayscale natively.

Still... square + power of two is extremely limiting.
Can't even think of a reason (opengl wise) why this limitation exists.
Code:
512, 1024, 2048, 4096, 8192, 16384 which corresponds to
8     16     32    64   128   256 in spring mapsizes.


Hmmm, would be interesting how well spring handles those extreme sizes.

64x64 (Block Wars) works alright. Go for 256! :D
