Based on the advice given by the mentor this week.
1. the controller's animation need be adjust (The unreal camera is not match the camera that I create in houdini)
2.Still need to lower the particle size
About The Import the Camera in Unreal From Houdini
Because my team members told me that Houdini's camera is hard to import into the Unreal engine. After doing some research, I found a way to import the camera into the Unreal engine.
the resource from : (55) Houdini to Unreal Engine 5 Camera Export - YouTube
The main part in houdini is to remember to export Frame Range.(Important!! otherwise the camera won't move)
The part in Unreal has same steps need to remember.
1. import camera in Actions(spanner shape)
2. import setting
3. Create Actor and make actor become parent to camera
4. Change the actor's transform
But in camera view, it still can't see the controller. After troubleshooting, I found that I change the controller's position (because the method we import grain into unreal can't change the position and it must keep it in (0,0,0), We have to make the other part to match the grain position(0,0,0) )
The reason why I can‘t see the controller in the camera view, because I change the controller's position to match the grain part.
The solution is that we need to transform the camera with the same position, I will get the right result.
The controller changed position (1.78, 0, 1.31) ,so the camera also need have to move this far.
Finally It worked.
The test frame 395(the controller's position is the same in the camera view.)

Unreal view
The camera with the movement also worked.

Regroup the controller's texture
The controller Fbx file don't have the texture group, but the texture already grouped in unreal which means I need regroup the controller base on the texture group.
texture group
each part base on the group name
regroup base on the texture group
Whole object
Adjust The Vellum Grain
Change the voxel size to 0.0005
Cause the voxel is small, the static sand also need be adjust.
The final result
