Summary

Hi, DanS ( Daniel )

Charly here

Nice to meet you

Your first mistake is placing MoovPhysics above HairFromGuides. It should be placed below HairFromGuides but after Edit Guides to make the simulation run faster.

I tested it on my end using the latest StandAlone version, and everything works fine. I created a simple ball animation and recorded a video for you. I’m also will attach a scene file for 3ds Max 2025 for your tests.

One more thing, which I also demonstrated in the video: In the Time Configuration settings, you need to disable Realtime. This will make the simulation more accurate. I showed both scenarios in the video.

TIMING:

0:00 - Showing the version of Ornatrix used, as the issue was tested on the latest stable version
0:05 - Demonstrating a basic animation quickly created using MaxScript for the example
0:10 - Assigning a Furball
0:16 - Selecting Edit Guides and applying MoovPhysics
0:20 - Highlighting that the modifier is placed after Edit Guides but under HairFromGuides
0:23 - Testing the simulation. It works relatively well, but there are occasional issues like stretching. A user on the forum reported that hair stretches as if there's no gravity. To fix this, Realtime needs to be turned off
0:28 - Demonstrating how to disable Realtime
0:34 - Retesting the simulation, which now works more smoothly and without errors
1:02 - Conclusion, other videos, subscribing to the channel, and checking out Artstation

Thank you and have a great day
Best regards,
Andrew.
