Thanks a lot for the explanation!
I replaced the plugin id with a user data and it seems to work ok. Still trying to figure out the matrix on the other thread though.

Here is the adapted code:

def main(): ID_PYGEN_DIRTY_CACHE = op[c4d.ID_USERDATA,3] linked_object = op[c4d.ID_USERDATA, 2] # Get the last cached dirty count and the current dirty count. lst_dcount = ID_PYGEN_DIRTY_CACHE cur_dcount = linked_object.GetDirty(c4d.DIRTYFLAGS_ALL) if linked_object is None: return c4d.BaseList2D(c4d.Onull) # Return the linked object if its dirty count exceeds our cached dirty # count or there is no cached dirty count. if lst_dcount is None or lst_dcount < cur_dcount or op.GetCache() is None: # Cache the current dirty count. op[c4d.ID_USERDATA,3] = cur_dcount clone = linked_object.GetClone(c4d.COPYFLAGS_NO_HIERARCHY) clone.SetMg(c4d.Matrix()) print "Built cache" return clone # Otherwise return the cache. else: print "Returned cache" return op.GetCache()

And the file:
python_dirtyState_0001.c4d

@m_magalhaes Thanks for the response Manuel, that was exactly what I needed.

@r_gigante
Thanks for the feedback.

FYI, this wasn't only with R21, had the same issue with R20, since the "old laptop" was restricted to R20 only. But I guess no updates will follow for R20 anymore.

Hi @gheyret, thanks for reaching out us.

Although @zipit has already provide an exhaustive answer to the topic (thanks man!) , I warmly suggest to look also to this blog post[URL-REMOVED] from @fwilleke80 and also to have a look at Navigation in Lists and Trees section on the GeListNode Manual.

Best, Riccardo

[URL-REMOVED] @maxon: This section contained a non-resolving link which has been removed.

@kbar Thank you for your response. That's really helpful, thank you.

@zipit said in How to handle C4D Unicode in Python scripting?:

well, that API object names thing is a flaw of Python 2. So working as expected or not as expected is a bit a question of the point of view. If you got the string passed from any other source the problem would be the same.

Right. The main thing is to understand the issue, and then to write the chapter in a way that explains what to watch out for. (I do wonder how third-party modules would do with a name string passed to them from a script that reads them from the API... well, another bridge to cross another day.)

Python 3 clearly is superior in that respect, as there is no unicode class and all str objects are unicode (what they appear to be already in C4D, but with matching len, index, and slice capabilities).

On a more productive note: I think that focusing in Unicode strings isn't really that important for
Python stuff in c4d, since object names should be something you largely ignore as they are a unreliable source of identification and only are rarely important in other contexts.

Hmm, I am not sure whether I would agree to that. Good naming is essential to find your way through complex scenes, and a good naming schema can be built in a way that is friendly to string search and comparison criteria, esp. if you can build your own scripts to perform the search and selection. I just point at the _L _R naming schema for joints that is common in C4D's docs.

Of course, if your objects are all named Cube, Cube.1, Cube.2, Cube.3, then name-based identification may be unhelpful 😋

Anyway, I am not the person to judge that, as I am only teaching Python to interested users. What they do with it is their own decision; I just have to point out the crucial points so they can apply the code to their own concepts.

I'm just going to go ahead and mark this as solved.
Either using an empty Basecontainer or the set function solve the problem.

Thank you for explaining!

FIELDLIST

works fine - i think i got an strange error before and trying CUSTOMFIELDLIST etc.

Hi,

well, aside from the "at least I am done with it"-approach of just adding 24 hours to each license, there is the static method UniversalDateTime::FromValues() which should be close enough to a FromString().

There is also UniversalDateTime::GetNow(). But the description on that is a bit ambiguous. It says "Return[s] the current date-time object of the current time zone.", while the UniversalDateTime class description says "Class that represents the Universal date-time (UTC+0000)". Unless I am overlooking something here, I would say both cannot be true at the same time, and would expect UniversalDateTime::GetNow() to actually return the current time in UTC +0 (as a UniversalDateTime).

The problem with DST is, that it is not anything truly predictable. While your problem could be rooted in a bug, there is a rich history of big organisations struggling with DST (Microsoft, Apple, etc.) and using DST makes you dependent on them maintaining their OS/services properly.

On a more light-hearted note: When dealing with standardisation of human conventions I always have to think of this XKCD 😉

OK, thank you!

Thank you, that's what I suspected 🙂

Hello,

as now said multiple times, GetActiveDocument() must not be used, but GetDocument() instead.

What is the point of your In/Exclude list? Are these the objects you "rotate along the timeline"?

This is typically not how a ObjectData object works; it generates objects based on its child objects or deforms objects in its hierarchy. It is not supposed to move arbitrary other objects.

As mentioned above, a tag plugin may be the better solution. The "look_at_camera" example show such a plugin rotating its host object.

best wishes,
Sebastian

hello,

I forgot to ask, where are you running those commands ? on a script, a dialogbox, a nodedata ?

Thanks for your time trying to isolate the problem. Don't hesitate to send us an heavy scene, we can see why the command isn't working.

Cheers,
Manuel

Hi Frank, thanks for reaching out us.

With regard to the reported issue, since we can easily end up in a lot of guess work, would you mind to privately share (email) the plugin to let us run some tests here?

Thanks, Riccardo

Fantastic, Thank you for the suggestions, ObjectDataOptimizeCache(true) does what I need.

Hi Manual,

Thanks for your help! Next time I will use the 'ask question' when posting a question.
You code does exactly what I need, much appreciated!

Cheers,
Martijn

@s_bach
Thanks for the response! Works as expected.

@zipit
No worries. Will close this thread.
I will probably revive this a year from now (lol). I have a feeling that Matrix will haunt me again in other aspects so this would be a nice exercise if that happens.

Thanks again!

Hi c4dmac, thanks for following up here.

With regard to the issue you've reported you can get fixed by reestablishing the executable bit on the kernel_app file found in the zip archive.
To sum it up, upon downloading the project tool archive you have to:

remove quarantine xattr -d "com.apple.quarantine" ./cinema4d_r21_project_tool_20190903.zip extract the archive (either via terminal or via finder) unzip -d ./cinema4d_r21_project_tool_20190903 ./cinema4d_r21_project_tool_20190903.zip re-establish the kernel_app executable bit chmod 555 ./cinema4d_r21_project_tool_20190903/kernel_app.app/Contents/MacOS/kernel_app

Best, Riccardo

Thanks for the input!
It's a shame you can't fiddle with the palettes. I think I'll just do it like x-particles and have a command that loads the palette and the user can dock it himself. Not the most elegant, but gets the job done.

Cheers
