I got it up and running on my 360, but for some reason on there the textures got mashed, the fog was fine though. I will...

After playing around with my clouds in the sky sphere I thought that the principle could also be carried over to fog, and it seems to work quite well! I am yet to tidy up the source and test on the XBox 360, as soon as I have it sorted I will post it. It's hard to see in a still, but the fog is actually...

Naturally the class' have had to be modified to pass the fog parameters and I have added a global static class that...

Now this is taken pretty much 99% from Leaf's example, but thought I would comment on how easy this technique is to put into your existing shaders. I also found that adding this to a shader...

Have found out how to do fog in the shader so this means that you can now have fog in your XBox 360 games as well as your Windows based games. As usual it is a matter of adding the right semantic and setting the correct renderstate in the shader. So, the code. Shader Model 1.1 - 2 In your Shader's...

I thought I would post this class first as it is relatively simple to implement and can be put into any XNA engine and is not specific to the HM Engine. Right, the effect of this class can be seen in the earlier post I gave for fog. So without further a do, here is the class: public sealed class Fog...
