ULON Base Material File Format

Material specifies which shaders the specific rendering pass will use to render. When you assign the material, the engine starts using its shaders to render the image.

A base material is a *.basemat text file that contains all the information to provide the final appearance for an object. The base material is created by programmers and cannot be edited via the Parameters window.

It is based on ULON file format declarations that define a base material with the given properties (options, states, textures, parameters, shaders and so on).

Besides the ULON nodes, a base material file can also contain an inline UUSL code or UnigineScript expressions.

The syntax is the following:

XML Code
BaseMaterial material_name <node=ObjectMeshStatic options_hidden=0 preview_hidden=0 var_prefix=var texture_prefix=tex>
{
	/* Other ULON nodes here*/
}

There are two types of base material supported:

  • BaseMaterial — base material for objects
  • BaseBrushMaterial — base material for terrain brushes
Notice
All node names in ULON are case-sensitive.

Arguments#

Notice
The argument names and values are case-sensitive.

editable#

Boolean

A flag indicating if all of the base material settings can be changed in the Parameters window or via API.

Available values:

  • false — unchangeable
  • true — changeable (by default)

hidden#

Boolean

A flag indicating if the material is displayed in the Materials Hierarchy.

Available values:

  • false — displayed (by default)
  • true — hidden

options_hidden#

Boolean

A flag indicating if the Options section is displayed for the material in the Common tab.

Available values:

  • false — displayed (by default)
  • true — hidden

preview_hidden#

Boolean

A flag indicating if the material preview is displayed.

Available values:

  • false — displayed (by default)
  • true — hidden

legacy#

Boolean

A flag indicating if the legacy mode is enabled.

Available values:

  • false — displayed (by default)
  • true — hidden

var_prefix#

String

The prefix added to the parameters when they are passed to the shader as a variable.

texture_prefix#

String

The prefixes that are added to the textures when they are passed to the shader.

defines#

String

The argument that specifies names of definitions that will be passed to all shaders.

node#

String

The type of node to which this material can be applied.

Available values:

default#

Boolean

Indicates that this material is used by default for the specified type of nodes.

Available values:

  • false — not used as the default material (by default)
  • true — sets as the default material
