Test progress ：

The crushing effect was tested with VAT How to export , Export normal , According to the normal , Play error ,Houdini  shader Parameters and unity  shader Parameter mismatch .

1、 In general unity In the environment of shader Show problems .

2、 stay houdini Missing... Encountered in shader Entry optional export question .

3、（ Replace the test unity The environment is URP）

Thinking switch

3、 The crushing effect is common unity It cannot be displayed normally under the project , Switching ideas ,（ Primordium FBX, and ABC Can be realized ）

4、 It is necessary to continue to test the fluid in unity Of URP Whether it operates normally in the environment ,shader Whether the display is normal .( Tested on URP The template is created normally , normal )

5、 Figure out how to convert particle fluids into faces , And connect VAT Export fluid effects .( Through the particle to face node (ParticalFiludSerface) node , To Noll(Out) node , On the way to VAT obtain Out The path export is normal )
