In the video you can see the light circle around the player. As the player moves into the shadow the shadows begin to flicker on and off. Also, the light is no longer being drawn. Each torch has a light. You can see it works for some, but the ones in the shadow seem to have a problem. Its like the shadow is overwriting the light calculation. I am not using any custom shaders.

Any tips on the shadow flickering? And why the shadows are preventing the lights from being drawn?

If I break up my walls/floors into multiple pieces the lighting works properly. My walls were 1 large piece, and the floor was one large piece.


I am not sure what that is? Is there a vertex limit?

It doesn't help with the shadow flickering in and out, though.

Definitely some sort of confusion with the lights and shadows
Could it be that your trying to cast shadows on the same objects that create them

Breaking up the objects might be the only solution
by the way this project looks like its coming along nicely

Objects can shadow themselves.

I got these issues, in my case it was the clipping......AGK will clip vertices behind the camera which means a wall, for example, casting a shadow can suddenly vanish, so then so does the shadow.

Try turning of fulstrum culling for the object.

EDIT: though I should say, that didnt fix it for me either. I think it's to do with how far behind the camera the rendering occurs.

Ah, now that makes sense. Because it always seems like its the shadows from objects that are either just out of camera range or close to it.

For the lighting I had to break up the objects. Not sure why that needed to be done.

For the shadows I had to turn off the walls casting the shadow. Again, not sure why, but that seemed to be the culprit for some reason.
