Hello guys,
I create simple HDA in houdini, key frame some translate and rotate in geometry node. But when bring it to maya, after press 'bake' button, the baked asset has no key frame in it.
I tried to google, but there is no infomation about this.

Hi there,

Unfortunately this is not possible with the bake functionality. The Houdini Engine for Maya plugin does not animate transforms. Instead, it animates the points of the objects directly. Because of this, a traditional transform animation bake will not yield the correct results. Instead, what you need to do is the following:

1. Select the object that you wish to bake
   
2. Go to Cache>Geometry Cache>Create New Cache>Option Box. Enter your settings, then click Create.
   
3. Select the Houdini asset node, and click Bake.
   
4. In the Outliner there will now be a copy of your object at the root of the scene. Select it, and go to Cache>Geometry Cache>Import Cache and select the cache that you created in step 2.
   

Your object will now be completely removed from Houdini while retaining the animation.

Thanks you, it worked.
But it would be nice if new version of houdini engine have option for parameter 'button' to run mel script or python in maya, so we dont have manually import the cache again, or have to write separate script in maya.
