Hi Logikoma

Thanks for the reply. I can't send the scene on I'm afraid, NDA issues. I can't reproduce it on a new scene, just the one I'm working on.

Hi again Logikoma

So it seems to happen with guides that I have planted myself, which suggests somehow Ornatrix isn't treating planted guides in the same fashion somehow. I've just had it come up again with a new model I'm working on, wihch had all its history deleted and was purposefully cleaned so as to rule out issues with mesh or surface anomalies.

Hope this helps and thanks a lot. I'm using Maya 2017 but also have experienced the same error in 2016.

Double post

Hi again Logikoma

So I think I have got to the cause of the problem. I had a saved custom groom that I was using to get started with my characters and something in that was causing the problem. In fact it was the casue also of very much reduced performance (especially when the GuidesFromMesh node was selected, there is a longer wait for the attribute editor to propogate which gets much worse with larger guide counts), which I'm glad to say has cleared up now that I'm not using that particular groom anymore.

Thanks again for your interest & help. I'm attaching the offending groom file for anybody who's interested....It would be nice to know what it is that was cuasing the slowdowns and errors so that I can avoid them in future.

OK, so I have run into this problem again which I can reproduce on my 2 different systems with the same process. To reproduce it, these are my steps.

1) Create a sphere

2) scale it up a bit in the scene

3) delete history

4) add Ornatrix and the Fur ball Groom setting

5) In the guides from Mesh node, set the number of guides to 5000 or so

6) Switch to edit guides shape

7) Select the brush mode in the edit guides panel and the Brush tool in the brushes panel

8) try and groom the guides. My experience is that they appear to be influenced by the brush, there's a pause in the system and then the guides snap back to their default position and the error I reported in the title of this thread comes up.

Maybe this is user error, but I'd really appreciate some help or clarification on what is happening here. This seems to be a new problem I hadn't run into before I started this thread.

Hi Logikoma

Great, glad you could reporoduce it and it's being looked into! Happy to help.

Also: A work around for this issue is to set the ammount of guides you want (eg 5000) and save the groom. Then you can add it to the object you're working on and there's no error. From my novice viewpoint, it seems Ornatrix isn't updating the guides list internally somewhere after initialization.

Will, do. Thanks again.

Sorry to report that I still run into this issue with build 1.3.9353, I've just repeated the process I detailed in an earlier post and got the same results again :-(

Great! Thanks Marsel.

Just to report back with some goodn news, the bug reported in this thread seems to be gone now. Many thanks to the developers for tackling this....Bravo!
