when move camera shaodow flaming too!shodow far from obj

try to play with camera.lens.far and the whole scale of your model. I’m really disappointed in shadows myself, and still tweaking them. but I got to improve them a little by changing the above.

It looks to me like a size problem I had. For some reason the shadows were way off from where they should have been, and the solution was quite unexpectable… Scale everything by lets say 10 times and see if it fixes it.
