Deformers and Polygon Tool selection

Alright. In this code, there is one indicator that made a difference:

// Global Registrant Method for IPPBase plugin
//*---------------------------------------------------------------------------*
Bool RegisterIPPBase(void)
//*---------------------------------------------------------------------------*
{
     return RegisterObjectPlugin(ID_IPPBASE, "iPP Base", OBJECT_HIERARCHYMODIFIER |OBJECT_MODIFIER|PLUGINFLAG_HIDE|PLUGINFLAG_HIDEPLUGINMENU, IPPBase::Alloc, "Oippbase", "Oippbase.tif", "Oippbase.tif", 0);
}

Guess which one?

Taking that out, if I then disable the deformer, I can select polygons. With this in (which is necessary for a 'hierarchy modifier'), nothing happens.

This is the problem with the Spherify example in the SDK. There are significant differences between your garden-variety deformer as exemplified and your hierarchy modifier - obviously.

All of that testing and checking and it all boils down to a single flag. Now, if the built-in bones work the same but don't show this problem, then there is information that is required to know why. Maybe there is a Message() or some other thing that must be done or handled that I am not.

I leave it to you (or the developers) to reveal the cause.

ETA: Try this with the Spherify deformer. That is, add the OBJECT_HIERARCHYMODIFIER flag to the registration method. Same situation.

Thanks,

Thanks for performing these tests and figuring out that OBJECT_HIERARCHYMODIFIER is the culprit. I have verified this with spherify.cpp and have asked the developers if there's a workaround available. (The built-in bones in 9.1 are not plugins, so they do not necessarily follow the same rules.)

Hmm, actually I still can select the polygons after adding OBJECT_HIERARCHYMODIFIER. (I just hadn't entered the polygon mode when I thought that I had reproduced your findings.)
Could you be more precise how you do to make spherify.cpp reproduce the non-selectable polygons?

And to be more precise as to what I did:

• Added OBJECT_HIERARCHYMODIFIER to spherify.cpp.
• Compiled. Ran C4D.
• Added a cube. Flattened it.
• Added a spherify deformer as its only child.
• Added another spherify deformer as a child of the other one, just to be sure.
• Selected the Cube. Activated Live Selection tool in Polygons mode.

The result was that the undeformed cube was shown and its polygons were selectable.

I did nearly the same. For the cube, I set the segments to 16,16,16 and flattened (or made editable). Spherify enabled or disabled, no selection possible.

This is an unmodified version of the R9.102 cinema4Dsdk (apart from the one necessary modification for the test) compiled using VC++ 6.0, running in Cinema4D R9.102, Windows. All other plugins moved out.

Modules:
- BodyPaint3D
- Advanced Render
- MOCCA
- PyroCluster
- Thinking Particles

Normally, under these circumstances, I'd say that it is something wrong with my Cinema4D install or some setting. But this has been experienced by the beta-testers as well.

I did just note that if "Deformer Mode" is disabled ("Turn On/Off Deformers"), selection is possible on the undeformed polygon object even if the deformer itself is enabled.

Let's see what might be the real culprit then. You are certain that you are using the modified Spherify?

The only change made to spherify.cpp:

From:
     return RegisterObjectPlugin(ID_SPHERIFYOBJECT,name,OBJECT_MODIFIER,Spherify::Alloc,"Ospherifydeformer","spherify.tif","spherify_small.tif",0);

To:
     return RegisterObjectPlugin(ID_SPHERIFYOBJECT,name,OBJECT_HIERARCHYMODIFIER|OBJECT_MODIFIER,Spherify::Alloc,"Ospherifydeformer","spherify.tif","spherify_small.tif",0);

Note that you need both flags for hierarchy modifiers. I have never been able to make them work without OBJECT_MODIFIER included.

This is "Win32 Release" Configuration compile. I just cleared the obj folder to get a clean compile again for more testing.

What the heck?

Here's what I'm seeing with Spherify. If I do 16 segments on the Cube, doesn't work. If I do 8 segments, it works. To be more rigorous, anything above 12 (XYZ) doesn't work.

Any ideas?

And to be even more rigorous, it appears that direct setting (click with Shift or Ctrl) works. It is only the Selection tools that seem to be having difficulty possibly with a certain number or density of polygons (will need more testing).

Both OpenGL and Software Shading were tested.

Looks suspiciously like a bug to me.

ETA: These revelations do not seem to hold for my own plugin hierarchy deformer though. Even a prop with only 1120 polygons won't select - not even Shift/Ctrl direct selection.

EETA: Although, a much simpler object, a Cone prop of only 90 polygons is selectable. Still unsure if this is quantity or polygon size or what (?).

Get's even better.

Good = Selection tools work with my plugin
Bad = Selection tools unreliable most of the time with my plugin

Windows:
R8.2 Good (undeformed)
R8.5 Good (undeformed)
R9.1 Bad
R9.5 Good (deformed)
R9.6 Good (deformed)

MacOSX:
R9.1 Good (undeformed)
R9.5 Good (undeformed)
R9.6 Good (undeformed)

What's interesting here, again, is that this is not isolated to my R9.1 install. Several other beta testers have noted the same problem, and one of them is definitely on MacOSX.

Something odd about this.

Hello Mikael,

How dumb. We never considered Viewport Configuration "Deformed Editing". Nothing to do with plugins or hierarchy modifiers (for the most part). Windows C4D R9.1 still does not work... if "Deformed Editing" is enabled. It does work if "Deformed Editing" is disabled. This would explain the difference between Windows and MacOS also - probably don't have this enabled in any of the versions there.

It is enough to drive you insane!

We can stop going on about this I think.

Thank you very much,

Robert
