Windows 11 - Human displays as shadow after render

[rwbaer]

Nightly Build: 20220719 alpha (HEAD:f8ff3bc5)

Steps to Reproduce: Start MH Switch to Rendering | Scene and observe what it looks like for current lighting Go toRendering | Render tab; click render Return to Rendering | Scene and observe that the display is a shadow now

Is this related to #198 and/or #204?

EDIT: IMPORTANT Going to the modeling or geometry tabs produces a human that is also just a shadow. The human can be seen when changing the rotation dynamically, but when things come to rest the human is again a shadow.**

The shadow honors "hide faces under clothers". If you uncheck this box, the "supposedly" hidden faces of the naked human show through the shadow. Could this be side-effect of fixing z-plane culling in the scene tab?

I have tried the same sequence on Ubuntu 22.04 and it works perfectly (no shadow at any point). Also no errors in the log. It sounds like an OpenGL problem in Qt on Windows - may be GPU specific and may be shader related. We might get more information if you run with: python3 makehuman.py --debugopengl --fullloggingopengl --debugnumpy (if you haven't already tried this). Also you might check your windows opengl drivers in case there is a more recent one. I apologise if I am suggesting stuff you have already tried. I am not sure what might cause this.

@kshepherd2013 thanks for the idea. When started this way there is no error or warning in the logs. My environment is: python 3.9 PyOpenGL 3.1.6 PyQt5 5.15.7 numpy 1.23.1 Windows 11 [Version 10.0.25163.1010] [ I have a 2060 super NVidia graphics card on this machine and the drivers are up to date]

Despite the logs being empty, there are a few lines on the console related to dict_keys and numpy that may make a difference (and I never remember seeing before), but I don't really know where in the program these might be coming from.

There also are some QWidget errors that probably shouldn't be happening. I think the ICC profile issues are long standing and haven't made an impact before although it strikes me that it would be nice to take care of them too some time.

I do not see anything from "QWidget" in mine, so you may be right that it is related to the "shadow" error. i.e. "QWidget::setMinimumSize: (/TextView) Negative sizes (0,-1) are not possible" I think the png ICC profile errors are not unusual.

[rwbaer]

Build f8ff31c5 Okay. I've been able to confirm this "shadow" behavior on at least 2 work computers and one home computer with various NVidia or Intel 630 graphics cards under Windows. numpy doesn't see critical having tried at least 1.23.1 and 1.18.1. pyopengl doesn't seem critical as it happen on both 3.1.0 and 3.1.6. PyQt5 version does not seem critical as it occurs with both 5.12.7 and 5.15.7. Python version does not seem critical because it happens with 3.7.6, 3.9 and 3.10. We are left with it is something unique to how either PYQt5 or openGL runs under Windows rather than Linux.

It would be nice if one of the other devs could confirm that they are seeing the differing behaviors Kevin is experiencing on Linux and I am experiencein on Windows 11. Also, does it happen on Windows 10 as well? It would also be nice to know what happens if we rollback to the version before we started to fix the 22.04 version to know if it is related to the fixes or is just an previously undiscovered behavior because rendering in MH is relatively uncommon. I could use a git refresher on exactly what would be the proper way to do that if one of you git experts can help.

[rwbaer]

I found a machine with Windows MH1.2.0 (20210426 final (HEAD:409e74d4) in which rendering is still working as expected.

[rwbaer]

As of build 1.2.1 alpha (master:1c4fa878) there is no shadow problem on Windows after render

[rwbaer]

1.2.1 alpha (master:d7e0c21a) 7/14/2022 2:04 AM I have now be able to verify that the shadow problem first appears with"Merge pull request #200 from ksheperd2013" Prior to that, the render tab does not produce a visible render, but at least the other tabs show a properly redered human. I think this commit should be reverted if a fix is not obvious. We can live with a "failing render tab" but not a completely broken interface on Windows

[rwbaer]

While it does seem we need to move to QOpenGLWidget , we may need to study the subtle changes that have happened to buffer updating and clipping to make sure we accomodate our complex GUI. See https://doc.qt.io/qt-5/qopenglwidget.html and particularly:

https://doc.qt.io/qt-5/qopenglwidget.html#relation-to-qglwidget https://doc.qt.io/qt-5/qopenglwidget.html#differences-to-qglwidget https://doc.qt.io/qt-5/qopenglwidget.html#resource-initialization-and-cleanup

This seems to channel some of the issuses that have plagued the "fix" "While the API is very similar, there is an important difference between the two: QOpenGLWidget always renders offscreen, using framebuffer objects. QGLWidget on the other hand uses a native window and surface. The latter causes issues when using it in complex user interfaces since, depending on the platform, such native child widgets may have various limitations, regarding stacking orders for example. QOpenGLWidget avoids this by not creating a separate native window."

Is the "shadow" an empty or non-updated buffer?

[rwbaer]

I removed 2 lines added to glmodule.py by kshepherd2013 [glEnable(GL_DEPTH_TEST); ] that seemed to be responsible for the "shadow behavior" on windows. I left his other modifications.

It will be important to find out if this breaks the Ubuntu 22.04 repair, or if they were unimportant to that repair. It would be great if one of you could try Ubuntu 22.04 with the changes.

[joepal1976]

My workstation is still at ubuntu 20.04, I haven't had time to update it yet. And running a test in virtualbox isn't really fair.

With ubuntu 20.02, I don't get a shadow but the zoom bug is there

[rwbaer]

There is a small side effect of having removed these two lines in Windows. The clipping plane on the front of the face after a render is incorrect. However this is only in the viewer tab after a render. The modeling tab and other tabs show the human as expected and seem to function normally with the exception of the zoom issue #208. On Windows overall functionality is better with the lines gone because there is no seeing anything with the black shadow in front.

[Aranuvir]

Same problem on my Linux-System, now. It looks like the shaded mesh is hidden behind the black object. Could it be a wrong buffer showing?

[rwbaer]

@Aranuvir - Just for clarity, do youn see the shadow with Ubuntu 22.04 or 20.04 (or both)? Should we move the ksshepard2013 fix to a feature branch until we get this solved?

Are we certain the old master code doesn't work on all Ubuntu 22.04 systems or is it just some of them?

Either way, I think we do need to move forward on QOpenGLWidget (useful links in post above It's a questionof what master is least toxic to sourcce users.

[rwbaer]

FWIW, with the current nightly I'm no longer getting the black shadow on Windows 11 when I render, but there is a new issue that mI describe in #225 along with a link to reports of back face culling issues by Ricardo2020 on the forum that may be related. If you think they are the same issue, you can close this and continue there from the Windows point of view.
