Strange glow surounding models

Unity Engine
1

Hi,

Anyone who can tell me why unity makes a glow around my models?
It is only when there is shadow behind it, so I’m thinking that it is some kind of anti aliasing gone bad?

Hi Lakru,

Thanks… would you care to file a bug report on this?
A simplified project boiled down to the bare minimum to illustrate the problem would be helpful.

In the meantime, we’re having a look

Thanks again
Caitlyn

This issue will be fixed by Unity 2.6.

Hey Caitlyn,
I’ll do that right away. I have just sended you a PM with another build where you can see the problem.

Oh, ok. So I dont have to send a bug report?

Could you explain what causes this?

It’s essentially a zbuffer precision problem due to differences in the pixel lighting shaders and vertex lighting.

You might be able to make it go away by increasing the near plane as well.

You can read about it here:

Cool that this will be fixed! I always thought this glow-issue was caused by the shadow blurring effect - doesn`t the glow disappear if you turn off smooth shadows? I might not remember correctly.
