RetopoFlow object rotation cleared when opening backup file via RetopoFlow menu

[kirkjaney]

Hello Im having an issue with the retopo program and Im having a difficult time trying to figure things out.... Whenever I reopen a file that I worked on from the previous day I noticed retopoflow always flip the source mesh and the new geometry up seperating it from the rest of the model. Is it possible to stop it from doing this every time? I can simply rotate it back down but now Im having a hard time realigning the body suit with the body. I've included a photo for you to better see the issue I'm having. As soon as I open up a saved file in retopoflow it immediately flips the source mesh and new geometry up!

Hello @kirkjaney , thanks for the report.
Can you send a .blend file where this happens to [email protected] with the issue number in the subject, so we can analyze it?

[jlampel]

I have not yet been able to replicate this issue with the file, whether saving while RetopoFlow is running or after exiting, but I did notice that the 'Extract3' mesh has two loose verts far above the head, which is very likely to cause some weirdness. It would also be worth applying scale and rotation. Does doing those three things fix the problem?

What’s happening is the following I select the drop down retopoflow option in the top left I select “open” then retopoflow brings the model into blender and I have to zoom out to see the model (I don’t know why the camera angle changes) but when Im zoomed out far enough to see the whole model “Extract3” and “Retopoflow” are automatically oriented facing up. The belly side of “Extract3” is facing up In case you can’t see the video I also attached a picture. It just shows how retopoflow likes to separate parts and pitch parts up that I previously worked on Click to Download <https://www.icloud.com/attachment/?u=https%3A%2F%2Fcvws.icloud-content.com%2FB%2FAb5AA_FzNwxt0my4qYRsstK7rtuHAcflcbbKzBt6poIGKECzUz4Hhlb5%2F%24%7Bf%7D%3Fo%3DAk9OxmngQmhRGvb6Zew9w-Cv20X58HR3-qZCw6GW0aR2%26v%3D1%26x%3D3%26a%3DCAognnAvhgyx5LNeiV3scQfmgiANvxM2WZWbKOVon_jOsIkSdhCbu5yluzIYm8uX-cQyIgEAKgkC6AMA_wEfKwlSBLuu24daBAeGVvlqJXuVcnuDh6PTZH9AMXuWvGxWc7Phd7L8z6Hflny5r39sazG1FZ5yJbBbdGKXei_6kRyiwT0oxCR2pVkbj4WRFVOHg92C3VfM0eZL2bk%26e%3D1736494671%26fl%3D%26r%3DBE8E1788-9F69-4CF3-A231-A5E909DE6DB8-1%26k%3D%24%7Buk%7D%26ckc%3Dcom.apple.largeattachment%26ckz%3DFF9617DB-77BD-4952-BE24-03F6F8EFA1B9%26p%3D71%26s%3DvY3imezBaM3CvkJcBIeSSCZ0Mso&uk=ytDcU7jioQAQDN4R9GDSOg&f=Screen%20Recording%202024-12-11%20at%202.05.58%E2%80%AFAM.mov&sz=53500075>Screen Recording 2024-12-11 at 2.05.58 AM.mov 53.5 MB

Oh, I see! This only happens when opening the file via the RetopoFlow menu and not Blender's File menu.

@jfranmatheu If I rename this file to retopoflow_backup.blend and place it in my Users folder (I'm on Windows, and that's where RF keeps the backups.... which is probably worth revisiting as well), it loads the file just fine if opened normally in Blender but with the RetopoFlow object's rotation cleared if opened via the RetopoFlow menu. Could you investigate further when you have a chance?

[jfranmatheu]

Thanks for the hint on the backup file location @jlampel I will take a look at it as soon as possible

[kirkjaney]

Mr. Jonathan, I really appreciate you for your help. I didn’t realize it was such a simple fix. Thanks again my friend KirkOn Dec 11, 2024, at 4:41 PM, Jonathan Lampel ***@***.***> wrote: Oh, I see!

@jlampel I've checked it. What I've seen is that if you normally open that file and then click on 'finish auto save recovery' in the RF menu, it will toggle on the visibility of the RF low-poly mesh but rotated (when originally it wasn't)

[jfranmatheu]

@jlampel

More interestingly, in the RF docs, is stated this

## Auto Save / Save: Finish Auto Save Recovery

If you directly open an auto saved file, some of the visual settings and mesh sizes will be different.
Clicking the "Finish Auto Save Recovery" button will recover the original visual settings and mesh sizes.

So, the "Finish Auto Save Recovery" button should recover the original visual settings and mesh sizes but it is also touching the transform settings far from the original settings.

Looks like the internal function that is changing the transform via transformation matrix is RetopoFlow_Blender_Save.recovery_revert, it is not only being called when explicitly clicking the "Finish Auto Save Recovery" button, but also occurs in a load_post handler called after opening a recovery file, so both options drive me to the same place.

[jfranmatheu]

@kirkjaney Can you try this RF build and tell me if it works for you and preserves the rotation? (attached)

RetopoFlow_v3.4.4.zip

[jlampel]

I wonder why rotation is touched by RetopoFlow here when, as far as I know, we're only scaling the objects. It makes sense that, in the event of a crash, some might be the wrong scale and the recover auto-save would correct for that. @vxlcoder can correct me if I'm wrong, but I can't find where rotation is involved at all in entering or exiting RetopoFlow mode (besides new targets being rotated to align with the active object if that's chosen), so I think we can safely leave that alone during recovery.
