I feel it every time I fly an airplane.
I wish I could add effects like this.
On the ground, it's okay if there is a shadow of the plane
Is it possible to say, "When the altitude is about 20m, the shadow on the ground disappears"?
It's strange to have a clear shadow on the ground at an altitude of 100m.
I've always been bothered by plane shadows being cast from a considerable height. I suspect this might be controlled in a .dll and hence be inaccessible to us mortals. I'll try a search through all classes, though...
The ideal treatment would be to have the shadow density decrease continuously until disappearance at some set distance.
My very first modding adventures were tweaking effects that other modders had supplied. Once I obtained the utility to extract files from the SFS files, the world was my oyster.
These days things are made easier with the Selector set to 'dump mode, all necessary resources being pulled out for you. Of course, adding new stuff often requires to play with Java. But for several years I did lots of stuff that didn't involve the classes.
There's a lot a beginner can start out doing just by trying out changes on existing mods...
