hi,guys.

I created a simple particle emitter HDA ,but in Maya it doesn't work, I don't know why(as in the screenshot),hope can help me fix the issue.Thank you for any help!

The warning is saying that the particles contain attributes that Maya doesn't support. If you don't need those particular attributes, you could ignore the warning. This shouldn't affect the particle simulation though. Would you be able to post your asset? Which Maya and Houdini Engine version are you using?

Thank you for your quick reply.I am using Maya2017 update2 and HoudiniFX 16.0633.Here is my otl file,Thanks!

This is likely due to the new evaluation modes in Maya 2016 and up. Try using the old evaluation mode. Open the Preferences window from “Windows -> Settings/Preferences -> Preferences”. Under “Settings -> Animation”, change the “Evaluation Mode” to “DG” to get the old evaluation behavior.
