选项

章节:

Fixed options of the material, their list cannot be changed. They are used to set custom values for common material options. The type of ULON node is Option.材料的固定选项，它们的列表不能更改。它们用于为常用材料选项设置自定义值。 ULON 节点的类型是 Option。

The syntax is the following:语法如下：

ULON

Option option_name = value(s)

Preprocessor Auto Generation for Shaders着色器的预处理器自动生成#

You can access options in the shader using the following defines:您可以使用以下定义访问着色器中的选项：

GET_OPTION_<option name in uppercase> — available for all types of options.GET_OPTION_<option 大写的名称> — 适用于所有类型的选项。

Option name	Option's define	Possible values
Transparent	GET_OPTION_TRANSPARENT	0 — opaque (default) 1 — alpha test 2 — blend 3 — water
Order	GET_OPTION_ORDER	-128..127 0 — default order0 — 默认顺序
Depth mask	GET_OPTION_DEPTH_MASK	0 or 10 或 1
Depth test	GET_OPTION_DEPTH_TEST	0 or 10 或 1
Two sided	GET_OPTION_TWO_SIDED	0 or 10 或 1
Cast shadow	GET_OPTION_CAST_PROJ_OMNI_SHADOW	0 or 10 或 1
Cast world shadow	GET_OPTION_CAST_WORLD_SHADOW	0 or 10 或 1
Overlap	GET_OPTION_OVERLAP	0 or 10 或 1

OPTION_<option name in uppercase> — defined only if an option has a positive value.OPTION_<option name in大写> - 仅在选项具有正值时定义。

Option name	Option's define	Additional define(s)
Transparent	OPTION_TRANSPARENT	0 — OPAQUE 1 — ALPHA_TEST 2 — TRANSPARENT_BLEND 3 — TRANSPARENT_WATER
Order	OPTION_ORDER	—
Depth mask	OPTION_DEPTH_MASK	—
Depth test	OPTION_DEPTH_TEST	—
Two sided	OPTION_TWO_SIDED	1 — TWO_SIDED
Cast shadow	OPTION_CAST_PROJ_OMNI_SHADOW	—
Cast world shadow	OPTION_CAST_WORLD_SHADOW	—
Overlap	OPTION_OVERLAP	1 — OVERLAP_RENDER

For various blend modes the source and destination defines are generated:
对于各种混合模式，生成 source 和 destination 定义：

UUSL

BLEND_SRC_FUNC_<source blend option name in uppercase>
BLEND_DEST_FUNC_<destination blend option name in uppercase>

// Examples
