[SOLVED] light shadow resolution not affect by radius

[cinetec_tech]

1:create a projection light and side point to a sphere around 25M away

2: adjust the light radius from 2000 to 30m

3: the shadow quality doesn't improve as you adjust the shadow radius to closer.

since you rendered the shadow depth from 0-1 so a tight light frustum should have a higher resolution.

is this a bug?

Hi Cinetec,

 

Unfortunately, it is not completely clear what you are trying to achieve. Could you please give us a sample or more detailed description of such use case?

 

Thanks!

from the pic i attached. you can see the shadow acne clearly.

i need a very low bias value to avoid offset of shadow.

as suggested in this article

change the far /near plane of the light should change the resolution of light shadow depth.

but in the engine. i didn't see much change at all.

Hi Cinetec,

 

1:create a projection light and side point to a sphere around 25M away

Projected and Omni lights are not using shadow cascades because of the performance.

 

 

as suggested in this article 

https://msdn.microso...4(v=vs.85).aspx

This article describes the world light shadows improvements (we already have shadow cascades and PCF for our LightWorld). Unfortunately, even if there were shadow cascades implemented for projected lights that approach would not work.

 

We also slightly improved shadow quality for all the light sources in the upcoming 2.2 update. Theoretically, it should help in your case too.

 

Thanks!

Thanks Silent:

   Do you known when is the next 2.2 release? 

 

thanks

Hi Cinetec,

 

We plan to provide a beta version until the end of February and release one a little bit later in the beginning of March.

 

Thanks!
