How to reduce the size of your mod.
Why does this matter?
After having to upgrade my web hosting package recently due to you lot busting my bandwidth limits :), I thought I'd have another look at my biggest mod to see if I could reduce its file size.

Currently the PilgrimMod.zip file is 41MB in size. Using the following tips I brought it down to 21MB. A ~50% size reduction.

Here are some comparison images.

Before2 , After2 , Before3 , After3 , Before4 , After4

There's very little difference. When you're driving through the track, there is no difference at all because you're watching the track, not the textures, and in peripheral vision, focus isn't required.

Quick reminder: Diffuse texture *D.dds: This is the image that gives the surface its detail.
Specular texture *S.dds: This is the image that gives the surface its shine.
Normal Map texture *N.dds: This is the image that gives the surface its bumpmap (lumpiness).

What to do:

Size does matter

First thing to do, is to half the size of the specular (*S.dds) and normal map (*N.dds) .dds files. Therefore create your diffuse *D.dds file as normal and save it.

To alter the textures surface shine, make changes to the lighting/contrast of this image (as you like), then using Photoshop

I have always been too lazy to test whether there really is any significant quality loss or not when reducing the size. Good to know after all ^^ Nice work Pop!
