Having an issue with shadow maps here. I've got the size of the map set to 4096, but I'm finding the shadow map isn't hittin everywhere I want it to..such as illustrated below.
Is there anything I can do to fix this? Should I bump the setting even higher?

A shadow map set at 4096 is probably already more complex to compute than a raytraced shadow. Are you using this map for the sun? Are you sure the mesh isn't the problem?

Yeah, it is a bit more complex to compute...takes FOREVER when it reaches glass but I didn't want to ramp up my AA for the entire image.
If I use standard raytraced shadows, this crease isn't there so I don't think it's a mesh issue. Those faces completely touch and are solid so there shouldn't be a light leak anywhere. And yes, it is the sun that I'm using. It's the ony light in the scene.
I may just have to Photoshop it and just watch for this with shadow maps

Maybe raytraced shadows with more AA will be quicker than this huge map. But I can't be 100% sure.
