Title: Problem re-sizing textures
Post by: Lord Tribble on April 14, 2009, 09:52:43 AM

I recently decided to downsize the textures of the ships in my BC install to take some strain of my poor laptop but have run into a problem with the CG soveriegn pack textures. I downsized them to 75% in photoshop the same way as I re-sized other textures, making sure they are the right format, but when i load the ships in the game, the ship is texture-less, completely white and everything lags to a standstill. Can anyone help?

Could you attach those textures?

I can't possibly upload all of them, but here's the resized emperor ID texture+specular from the shared textures

I did a bit of testing with just the Emporer ID texture, the ship comes up without that texture as if it can't find it. Even though it is there and , as far as i'm aware, the same name/fileformat :(

That's what I suspected. The texture size has to be any power of 2 like 128x128, 256x256, 1024x1024 etc..

Ok, i've never been great at maths.....so it's not working because that texture is 768x768?

what % scale do you suggest I down scale the (mostly) 1024x1024 textures too so they'll work?
I don't really want to go as far as 50%

Thanks =)

Exactly.

unfortunately the first size smaller than 1024 that  BC accepts is 512. You could try 1024x512 but
you'll probably have to fix the UV mapping then.

so the next highest I can do is 512X512 (or 50% for everything)?

I just did a 3D module at uni, recreating an area from world of warcraft in Maya, and i never EVER want to go near uv mapping again lol :lol:

Try to thnk of it in pixels, rather than Percentages. Basically, the size of BC Textures works in doubles. For example:

1x1
2x2
4x4
8x8
16x16
32x32
64x64
128x128
256x256
512x512

Like that, basically. Hope this helps. :D

Thanks for the help guys :)

I just tested that and found out that no uv mapping is necesarry.

i've just resized them to 512 :)

I run BC in windowed mode (mainly to lighten the load on my graphics card abit more and to avoid stretching on the widescreen) and it still looks pretty good :mrgreen:
