Hey @cairyn,

yeah, you are right. @m_adam already pointed this out too. I screwed up and overwrote my clipboard when I tried this out. I have edited my initial posting, to not confuse future readers.

GetC4DClipboardOwner works fine in regards to the Picture Viewer and Bodypaint, but the argument ownerid of CopyBitmapToClipboard is effectively meaningless in the public API, as it lacks the window handle context to actually cause the ownerid to be stored. The owner id will always be set to 0.

And to underline the answer to your major question: It seems very unlikely that you could crash Cinema 4D with writing a made-up owner id into the clipboard (in the case the function would work properly and actually store the id). It is hard to give here absolute answers, as there is a lot of code in our code base. In the context of the clipboard alone, crashing can be excluded, but there could be other parts of Cinema 4D which make assumptions based on the owner id. Which is why I would recommend not using the predefined ones (which is rather theoretical due to said limitations of CopyBitmapToClipboard).

Cheers,
Ferdinand

@noseman seems that it's needs to be updated

@m_adam
Thanks so much!
You are a very professional guy!!!

hi @cinamatic ,

You should open a new thread for your question as it is not related to this thread.
I found this thread where you will find some useful information about takes and material.

If you have any question, please open your own thread explaining what you are trying to achieve and pointing to those different threads. Futur user will find every information to follow the discussion.

Cheers,
Manuel

@m_magalhaes Thank you!

Hello @lingza,

well as lined out, you cannot implement a VertexmMapTag which is the same as a normal VertexMapTag but has extra parameters to realize your desired functionality.

You can solve this problem with either the pattern I described under point 3 in my last posting, or by implementing a ToolData plugin which simply generates the tag. The solution using a driver tag has the advantage that the user can continuously tweak the output of the vertexmap, while a tool must be picked up again.

Actually, I mean that I want to create a tag which contains the vertex weights, then vertex weights are used by ZRemesher after I put the tag into Density Map linkbox.
So I don't need a "vertex map" indeed, but I need a tag I describe above.

This is unfortunately not true. You will need a vertex map tag, as this parameter, the Density Map parameter, will accept only a VertexMapTag. It will not know what to do with a CustomDataTag . I would recommend having a look at the project file I have posted above, it contains a practical example for the pattern of a tag driving a vertex map.

Cheers,
Ferdinand

Thanks for the update!

Thanks did report

Okay, thanks!

@m_magalhaes - All good! Just wanted to make certain that the issue hasn't been fixed yet (since 2018..).

In the future I'll write a python class, extending a group that is collapsible using the workaround you mentioned.

Thank you for getting back to me and looking into this! Cheers.

Thanks so much!!!

Your answer makes me understand that PolygonObject.GetPolygonS(self) and PolygonObject.GetPolygonH(self) respectively represent selection states in a list from BaseSelect and visibility states in a list from BaseSelect.

Hi,

I am looking for hit point. Then if I understand well, my only way would be to use GeRayCollider on all objects ?

A point-something projection will also give you a "hit-point" in some sense. The question is if you want to find the closest point for a point on some geometry (projection), or a point on a geometry for a point and a ray (intersection). GeRayCollider realizes ray-triangle intersection testing for PolygonObject instances. For multiple objects you must initialize multiple collider instances (or reinitialize one instance). But you cannot intersection test a null, a spline, or joint object as shown in your screenshot as they do not contain any triangles. When you are just interested in the closest point in some discrete geometry, you can use ViewportSelect or the more modern maxon API equivalent maxon::DistanceQueryInterface with a slightly different and more abstract purpose. ViewportSelect can also be used to pick the object in a scene which is closest to a point (for the cursor for example) for further testing with other methods.

In maxon::GeometryUtilsInterface you will find some basic building blocks for writing something of your own.

@kbar I think much better to create your own Edit Script dialog with blackjack and... Save and Execute Buttons. Use GeDialog.AddMultiLineEditText with a flags DR_MULTILINE_SYNTAXCOLOR and DR_MULTILINE_PYTHON.

Hello @mikeudin,

Thank you for reaching out to us. Vectors represented by the type c4d.Vector are immutable in Cinema 4D, so one intentionally cannot change one of the components of a vector after it has been instantiated (matrices are not immutable over their vector components on the other hand). To achieve what you want to do, you must write:

old = Cube[c4d.ID_USERDATA, 2] Cube[c4d.ID_USERDATA, 2] = c4d.Vector(old.x, old.y, 12)

The following would also be possible, but it is not an improvement IMHO:

Cube[c4d.ID_USERDATA, 2] = c4d.Vector(Cube[c4d.ID_USERDATA, 2].x, Cube[c4d.ID_USERDATA, 2].y, 12)

Cheers,
Ferdinand

Great, thank you guys!

Cool! Thanks for your community work, Kent!

Hello @m_magalhaes ,

Thanks a lot for the tip, works perfectly as you said 😁

Since this question is tagged as C++, I'll add the docs link to the dedicated functions that return and set this attribute:
BaseObject::GetDeformMode() and BaseObject::SetDeformMode()

@m_adam said in macOS Monterey - Can't run source processor anymore?:

So you have to link for example from /usr/local/bin to a python installation, I personally have Python 3.8.9.
Xcode itself ships with a python version you could link to (its in Contents/Developer/usr/bin of the application package).
So with that path you can call call sudo ln -s PATH_TO_PYTHON /usr/local/bin/python in terminal.

Hi Adam!

That is in deed what I tried, creating a symlink that points to Python 3. I didn't use the paths, though, but just linked the word "python" to "python3". I guess that was my mistake.

Wouldn't it be easier for Maxon and everybody else, if you just changed the preprocessor call in the projects' PreBuild events to "python3", instead of having to go the symlink way and change things on users' computers (which, I guess, will have side effects when users later decide to install Python 2.7 for some reason)?

Cheers,
Frank

@cairyn
It Works. Thank You. Very Much.
