I cannot reproduce this with the steps described. Please try to reproduce it in a clean scene with the latest nightly build and share it here.

It always stops working if I add/delete guides if I use "guides as hair" interpolation in "hair from guides" modifier, even if the "edit guides" modifier below the "hair from guides" one.

But if I apply one more "edit guides" modifier on top of hair from guides modifier, it also stops working, if I add/delete guides, regardless of interpolation used in "hair from guides" modifier.

I tried clean 3ds max install, and also 2 different versions - 2022 and 2023. For 2023 I used v7, and for 2022 v8.

Here is a shorter, more concise video of the problem

Here I only use one edit guides modifier, and hair from guides on top with guides as hair interpolation

Is this the same issue as: https://ephere.com/plugins/autodesk/max/ornatrix/forums/private/thread_14457.html

Yes, it is

It seems painting channels is also not working. I'm not sure why. I tried both 7 and 8-th version, they both have glitches. My work has stalled, I don't know how to proceed with the project.

I try to paint a map for hair clustering modifier, but neither painted map, nor paint channels work properly.

The painted map is being ignored by the modifier.

Should I reinstall windows or something?

 

I tried another version (7.3.6.30261), but still hair clustering maps won't work

By the way, clump modifier amount map works. So some maps do work, but some don't

EDIT: clump maps also stopped working after deleting some strands in edit modifier.

 

I testet it on another machine, a fresh 3ds max install, Ornatrix 8 demo. It seems it has the same problems, that is:

-deleting/adding guides in edit guides causes change width map not working, if guides as hair interpolation is used

-hair clustering distribution map is not working

 

The only workaround is not using add/delete guides function, and avoiding using hair cluster modifier for realtime pipeline.

Sorry for the delay.

I followed the exact same steps from your video.

Ornatrix V7.4.1.32215, which is the latest nightly build available for version 7. Max 2022:



V7.4.1.32215, Max 2023:


I will ask someone else in the team to give it a try, but I can't reproduce it.

Try the Clump modifier. Cluster is deprecated, we don't support it anymore.

EDIT: clump maps also stopped working after deleting some strands in edit modifier.

The Clumper relies on strand topology. If you delete some guides you have to Regenerate the clumps.  

 if guides as hair interpolation is used

Well, that's new. I can reproduce it if I set Hair from Guides to Guides as Hair. We'll have it fixed soon.

The problem with Change Width and the multiplier map is solved in the next nightly build. 

Jeordanis Figuereo (Product Designer. EPHERE Inc.)

Hi, thank yoiu for the response!

Yes, ox clump amount map works, only change width does not after deleting guides.

Please let me know when the new build available, thank you!

You will see it in the download page as nightly or stable release. You can also track new releases here
