+# Houdini Mass Translator
+
+Welcome to the [repository](https://github.com/AdrianPanGithub/HoudiniMassTranslator) for the Houdini Mass Translator For Unreal.
+
+This plug-in provides seamless integration between Houdini Engine and Zone Graph, allow zone shape input and output.
+
+# Compatibility

+
+# Installation

+03. Extract the **HoudiniMassTranslator** and **HoudiniEngine** to the **Plugins** of your Unreal Project Directory.
+
+    e.g. `C:/Unreal Projects/MyGameProject/Plugins/HoudiniMassTranslator` and `C:/Unreal Projects/MyGameProject/Plugins/HoudiniEngine`

+Support both input and output of mass ai zone shapes
+
+There are some attributes for zone shape input and output
+
+i@**unreal_output_zone_shape**
+
+    = 1 on detail, all curves will output as zone shapes
+i@**unreal_zone_shape_type** / s@**unreal_zone_shape_type**
+
+    define whether a curve is represented as zone shape spline or polygon (intersection).
+s[]@**unreal_zone_shape_tags**
+
+    specify zone graph tags on zone shape.
+d[]@**unreal_zone_lane_profile**
+
