fading fog into a skybox

[BlindSide]

I guess you can precompute a "depth map" for the each skybox face and use that in your fog computations. You will need 2 passes and a custom post processing fog shader though.

It is a neat idea though, I may try it since you will be able to change the colour based on time of day etc and it will sort of bring your skybox to life.

I am also working on a space game.
I have a stars skybox and a grid made of lines which should fade into the skybox in the distance.
I solved it by setting MaterialType to EMT_TRANSPARENT_ADD_COLOR.

SMaterial m;
m.Lighting = false;
m.FogEnable = true;
m.MaterialType = EMT_TRANSPARENT_ADD_COLOR;
driver->setMaterial(m);



I am using this with draw3dline but there should be a way to do that with objects also.

Hope it works for you!

Hi WishFish,

Seems not to work in my case

OMG! I GOT IT!



I set Fog Color to:

Code: Select all

SColor(0,0,0,0)

and the following to the node:

Code: Select all

planettemp.node->setMaterialFlag(EMF_FOG_ENABLE, true);
planettemp.node->setMaterialType(EMT_TRANSPARENT_ADD_COLOR);
planettemp.node->setMaterialFlag(EMF_LIGHTING, false);

There is just one mistake left, as you can't see the earth ist always translucent not only if fog reaches the earth. But i will try to fix it soon...

MFG
