Summary

Thanks for your quick response Jeordanis . Look forward to the fix.

Hi Jeordanis,

After a few rounds of testing, I figured out what's going on when you reopen a maya file and the strands group index mess up.

This only happens when a the ornatrix base mesh is deformed.

I attached a sample file. When you open it, all the stand groups look fine. But if you do the following steps:

1. Scale "wrap_control" object in Y-axis (So now the Ornatrix base mesh is deformed as well because of wrap deformer)

2. Save and close the scene.

3. Reopen the scene. You can notice some strand group index jumps back to 0.

This test is based on the latest stable 2.1.1.14888.

Btw, the strand group reassign index issue is fixed. Thanks for that!

I'm currently stuck on this issue can't move forward to render the project. Would be great if the dev team can have a look of this. Thanks!

Hi Jeordanis,

Thanks for letting me know and dev team's effort. 

However I'm still having the same issue when ornatrix base mesh is deformed, then the starnd group id change to 0. Do you mind download the scene file I attached in the previous post and follow the steps I mentioned? 

I think the actuall problem is when base mesh is deformed (like wrap deformer), it will also affect the strand group index which isn't right.

Would be great if you can test the scene file. But thanks again to you and the dev team!

Cheers,

Shawn
