|
label: Maximum shadow distance
|
|
description: >
|
|
This controls the maximum distance up to where shadows
|
|
are rendered. A higher distance means further shadows,
|
|
but also a worse shadow quality.
|
|
|

shader_runtime: true
|
|
label: Logarithmic Factor
|
|
description: >
|
|
Controls the logarithmic factor of the splitting scheme. Lower
|
|
values mean a more linear distribution, while higher values will
|
|
move the splits closer to the camera.

type: float

range: [100.0, 10000.0]

default: 100.0
|
|
label: Sun distance
|
|
runtime: true
|
|
description: >
|
|
This controls how far the sun is away from the scene, to avoid
|
|
clipping objects outside of the frustum which still cast shadows.
|
|
Basically you don't need to adjust this setting, but in
|
|
case you get artifacts, try increasing this setting.
|
|
|
|
- split_count:
|
|
type: int
|
|
range: [1, 20]
|
|
default: 5
|
|
label: Amount of PSSM Splits / Cascades
|
|
description: >
|
|
This controls how many splits are used for the PSSM.
|
|
A higher amount of splits increases the shadow map
|
|
detail and quality, but also increases the performance
|
|
cost by a lot. For every split, the scene has to get
|
|
rendered again, so be careful when choosing high amount
|
|
of splits.
|
|
|
|
- resolution:
|

type: power_of_two

|
range: [128, 4096]
|
|
default: 1024
|
|
label: Shadowmap resolution
|
|
description: >
|
|
This controls the resolution of the individual shadowmaps
|
|
of the splits. If you choose a resolution of 512 for example,
|
|
and you have 10 splits, then that makes a total resolution
|
|
of 5120 * 512 for the shadow map. Be careful when choosing high
|
|
defaults, the shadow map will soon take a huge amount of VRam.

Increases the shadow map size of each cascade by a small factor, to

ensure seamless filtering between cascades. If you encounter artifacts
|
|
between cascades, increase this value.

- use_pcf:

type: bool

label: Use hardware filtering (PCF)
|
|
description: >
|
|
This setting turns Percentage Closer Filtering on or off (A simple
|
|
2x2 bilinear filter provided by the GPU).
|
|
It provides a better shadow quality, and theoretically a better
|
|
performance. However, not all GPU's seem to support it.

|
|
default: 0.55
|
|
shader_runtime: true
|
|
label: Filtering radius
|
|
description: >
|
|
This setting controls the filter size, higher values mean a more
|
|
smooth penumbra. Too high values might (and will) produce artifacts.
|
|
This setting has almost no measureable impact on performance.
|
|
|

- fixed_bias:

range: [0.0, 2.0]
|
|
default: 0.48
|

shader_runtime: true
|
|
label: Depth Bias
|
|
description: >
|
|
Depth-Based bias. This avoids self-shadowing issues (also known)
|
|
as Shadow-Acne. Too high values will produce gaps in the shadows,
|
|
so try to find the lowest possible value.
|
|

default: 0.11
|

shader_runtime: true
|
|
label: Slope Bias
|
|
description: >
|
|
Slope-Based bias. This avoid self-shadowing issues as well, but instead
|
|
of the fixed bias it adds bias based on the angle between the light
|
|
and the surface.
|
|
|
|
- normal_bias:

type: float

label: Normal Bias
|
|
description: >
|
|
Normal-Based bias. This moves the sample position by a small amount
|
|
into the direction of the surface normal, to avoid self shadowing.

|
|
type: bool

default: false

shader_runtime: true
|
|
label: Use PCSS
|
|
description: >
|
|
PCSS adds support for variable penumbra size shadows. Without PCSS,
|
|
all shadows have the same penumbra size at all places. With PCSS,
|
|
the shadow penumbra size increases based on the distance. However,
|
|
PCSS requires additionally computations, and thus is slower than
|
|
regular filtering.

label: PCSS Penumbra scale
|
|
description: >
|
|
Scales the penumbra by a fixed factor. This is an artistic setting,
|
|
and does not affect performance much. Lower settings will cause a
|
|
smaller penumbra, while higher settings produce a bigger one. Too
|
|
high values might cause artifacts in the filtering.

- use_distant_shadows:
|

type: bool

default: true
|
|
label: Render distant shadows
|
|
description: >
|
|
When this setting is enabled, an additional shadow map is generated
|
|
to render distant shadows, e.g. for terrain. This makes it possible
|
|
to set the pssm distance very small, but still recieve shadows from
|
|
big objects. If your scene is not big, this may not be required.
