Question Light seams shine through shadow

for some reason, every verticle shines light, they dissappear when camera gets close.

floor is made of a lot of square planes, how do i prevent this light?
btw i get rid of outside light sources, this light seams makes no sense.

 

it could be a shadow distance thing. When your shadows cut out, well,. you end up with similiar results as i am seing here. OFC, theres other possibilities at play. Lighting iis one hell of a 'job'

 

yeah, i tried to mess with shadow settings, i give up, lighting is fun until this happens i guess.
or i may put one single super big plane.

 

Try that and see what happens.

 

Stop... Dont put it on a big plane, address the issue. Theres a few possible causes:

• Shadow rendering distance.
• Your settings for GI, as GI lighting tends to light up from the bottom and sides.
• (Work around) Reflection Probe.

A game dev will address the current issue, instead of resorting to a "drastic measure". Come on bro, you got this...

 

i dont know, i am kinda new

 

Try turning on 'Two Sided' option for 'Cast Shadows'

 

didnt work

 

You need to mess with the normal bias and bias. Start by setting both to 0, which will cause shadow acne, but get rid of the leaks (hopefully). Then adjust one or the other up



However, if you fix that, you may have other issues.

Shadow rendering in Unity is kinda bad; newer engines have mitigations and workarounds such as automatic detection/adjustment of bias parameters based on screen space derivatives, but (except maybe HDRP VSM; I don't know much there), Unity seems to be back in like early-2000s era with shadow tech. The easiest solution might be to create a plane and set it to "shadows only"

 

lightning is made with emmission, those settings probably doesnt exist for me

 

Emission does not cast real-time shadows; just baked shadows.
