Hi Tim …
First of all I want to thank you for fast responding , which is so appreciated , and honestly I was hoping that is you are the one who will answer my questions due to your experiences and helping me and a lot of other people throw your answers before .
and I will use your method to reply…
1: light bleed
I know that there is a Cascaded Shadow adjustments for directional light but it was not enough to solve my bleeding cause as they said it has limits , and that is way I had to use ray traced shadow which is solved my problems outside but the picture that I put its link before 2016-01-05_1417 was showing bleeding from inside which is coming from point lights and as you said it has no Cascaded Shadow adjustments, and even if there is an option like so , I wonder if it will be effective , and that is why I turned my point light shadow to ray traced shadow too but then it gives me this problem 2016-01-05_1413 , and it will disappear when the shadow is not ray traced , so I’ am between two problems either bleeding lights or not accurate shadows.
2: Distance Field RayTraced Shadows
and here is my mesh distance field visualization http://screencast.com/t/IQAE4ZlGo5 wondering if it will help to show my problem http://screencast.com/t/l978vvX3 and this Link did not help me to identify quality and troubleshooting these types of issues although it was pretty useful .
3: Stationary Light BP
CLEAR
4: Direct Shadowing/Sky light shadow color
changing the light color and Intensity will not help me at all cause the the light color is already white and nothing is brighter than white and changing them will not only effect the shadow but the light too
I hope that you can help me more but I really thank you so so much
