Light Bleeding Along Edges

Recommended Posts

  • i have a cube as a room with 2 lights, one out side and one inside.

    seems the light out side is bleeding inside along the corner and edges along the wall.

    how would one stop this.

    i remember some where along this topic that it had to do with the shadow settings but for the life of me i cannt remember how.

    You can give the wall some thickness , extrude with the caps option on.

  • disable "absolute bias" in shadow tab

    then turn up "bias (rel)"

    thats not working!

    i then switched the shadow map to 2000x2000 and that minimized this bleeding down to about 1%

    but the corners still show a little bit of the light from out side.

    here is the scene file.

  • you could just change your shadow to area shadow

    could this be a bug in V10-10.1?

    cause now i do remember this was the way to go in the demo of v9.1 and i believe in v10 too.

    need more feed back from people that havent updated to V10.1 yet.

    Either....put a polygon outside of the corner to block light, lower the bias but don't turn it off, or bevel your corners slightly so they are not complete 90 degree angles. (they wouldn't be in real life anyways)

    Or another option would be to make all the walls into one object and weld their edges together. That would prob sort it too...

  • Another option.. use a cube for the outside walls of your room and zoom inside. Use booleans for the windows and doors. Light shouldn't leak in then since there would be a solid framework for the outside walls. Just a thought. ;-)

    im using a cube (primitive) that has cuts for the window and the safe recess.

    might just have to remodel the whole room (cube).
