# Batcher
|
|
|
|
This setting determines how the meshes are combined. We provide two options here:
|
|
|
|
## MaterialPreservingBatcher
|
|
|
|
|
|
|
|
HLOD meshes are created by grouping meshes with the same material. We use the existing material as it is.
|
|
|
|
## SimpleBatcher
|
|
|
|
|
|
|
|
Even if the material of adjacent meshes is different, we always merge
|
|
the meshes and create a new material for the merged mesh. To do this
|
|
properly, we need to combine the textures referenced by different
|
|
materials into textures referenced by the new material, and
|
|
accordingly perform UV-remapping when building the merged mesh. We
|
|
have a number of settings that specifies how this process should be
|
|
performed:
|
|
|
|
**Pack texture size**: Sets the size of the generated texture atlas.
|
|
|
|
**Limit texture size**: Sets the maximum area each source texture
|
|
occupies. If (because of this setting) there is unused space after all
|
|
source textures are copied to the generated texture atlas, HLOD system
|
|
will try to reduce the size of the generated texture atlas.
|
|
|
|
**Material**: Sets the material for the merged mesh. If not set, we'll
|
|
use *Standard Shader*.
|
|
|
|
**Textures:** An entry X-Y here means we find all textures referenced
|
|
as property X from materials used by meshes in the HLOD hierarchy,
|
|
merge them together into a combined texture atlas and set this texture
|
|
atlas as parameter Y in the new generated material.
|
|
|
|
Note that this means HLOD system would only work properly if all the
|
|
materials used by the meshes in the HLOD hierarchy have a similar
|
|
texture input naming convention.
|
|
|
|
**Update texture properties:** The **Textures** setting tries to
|
|
collect appropriate material properties for the GUI drop-down, but
|
|
sometimes this does not work properly. Press this button if some
|
|
material property you want to use for the **Textures** setting is
|
|
missing. |
