shadows don't connect to the base of the objects casting them?

Unity Engine

Hello!

Hoping to get some help with this. Maybe this is something super simple but I cant seem to find it. Does anyone know why the shadows in these screenshots / my scene aren’t matching up to the base of the object? They seem to be perpetually offset no matter how I adjust the light, shadow, and lightmapping settings.

I’m just messing around in a simple scene with cubes and a plane to get the hang of lightmapping and ran across this issue. The first two images are unbaked and the last image is with soft shadows baked.

Thanks!

Try tweaking the Bias value on the light.
To high values give you seperation, but to low will produce massive shadow artefacts.

Thanks for the quick response! I can see the Bias value when the light is set to Realtime or Mixed but not in Baked. I tried setting it in Realtime and switching back to Baked but it doesn’t seem to retain the Bias value. For what I’m planning to apply this testing to I’ll have all of my lights set to Baked so this still remains a problem.

In case its relevant I’m in Forward - Linear rendering.

Oh and this is on 5.1.1p3 on Win 8.1

Any thoughts since Bias value is not available w a light in baked mode?

Is not having Bias value available if a light is set to baked true for everyone else? Or is this a bug on my end?

Perhaps you could try increasing the texel count for your lightmaps, maybe this would solve your issue?

I wouldn’t worry about minor things like this, everything is just an approximation of reality, no one is going to notice an issue like this. They’ll be more concerned with how fun your game is.
