+## SET_ENTITY_DRAW_OUTLINE_RENDER_TECHNIQUE
+
+```c
+void SET_ENTITY_DRAW_OUTLINE_RENDER_TECHNIQUE(char* techniqueGroup);
+```
+Sets the render technique for drawing an entity's outline. This function allows you to specify a technique group name to control how the entity's outline is rendered in the game.
+
+Passing an empty string as the `techniqueGroup` parameter will reset the render technique to its default value.
+## Parameters
+* **techniqueGroup**: Technique group name.
