Hi @shafy sorry for the delay I was away for few times. Before we start please read the Support Procedure - About AI-Supported Development. Keep in mind we are not there to develop for you neither integrate or guide you with 3rd party module that you will most likely need in order to control knobs. With that's said what you are asking (at least retrieving a parameter and defining it) is possible for Redshift light intensity. It is as easy as drag and dropping the parameter you are interested by into the Cinema 4D Python Console as explained in Python Script Manager Manual - Drag And Drop. Additionally you can also use the Script Log to record a script or change and therefor re-execute it. Cheers, Maxime.

This is fantastic, thank you so much! This works beautifully. I see your confusion with the "offset". This is absolutely my fault in formulating the question. Sorry about that. I also wanted the clones to follow a spline with an individual offset, but then thought to remove this part to not overcomplicate the question and accidentally left some traces. However, in your video you gave me valuable insight in how to achieve this as well. I already have a working sketch where I'm daisy chaining your script with a Spline Effector in the right order. Giving these thoughtful answers is incredibly valuable, you can't believe how motivating this is to go further.

Hey @Fabio-B, Please note that we cannot provide support for AI generated code. See Support Procedures: Scope of Support for details. When you want the clones to move, or in other words to be animated over time, you will need a noise and cannot use hashes or random values, as they are not interpolated, i.e., continous. """Realizes an effector that attracts MoGraph particles spherically around its origin. Add the example to a Matrix object to understand its effect.

Hey @m_adam, Thanks for the reply! What you’re saying makes a lot of sense C++ is clearly the better option for this kind of stuff, especially when you need more control and better performance. I haven’t had much chance to dive into C++ yet, but I’m well aware it’s way more powerful than Python when it comes to working with the engine. It’s a bit of a shame that there’s no way to directly access polygon info from Python, since that’s exactly what I needed. But still, I really appreciate you taking the time to explain it. Cheers, James H.

@ferdinand Thank you for your detailed explanation, it shed some light on the whole matter for me.

@i_mazlov said in Frozen Matrix different: 象，并且没有其 I found that it's very similar to the offsetParentMatrix attribute introduced in Maya 2020.：）

@hoganXYZ hi if it does not appear in the script log then there is no clear rules. Sometimes there is another way sometimes now it depends on how it is implemented. For the one you asked I do not think it is possible. Best bet would be to ask Redshift on their forum. Cheers, Maxime.

Hi I was able to reproduce the issue and fix it for the next version. The bug is that setting RDATA_FRAMERATE require the RenderData to be part of a document in case the "Use Project Frame Rate" is enabled on the render settings. If this is enabled and this is enabled by default the value you enter will be disregarded. "Use Project Frame Rate" is a new setting added in 2025.2. I will ping you once the fix is available. Cheers, Maxime.

Hi Ferdinand, Thanks a lot for the clear explanation and for taking the time to share the code. The part about accessing BaseVideoPost and using REDSHIFT_RENDERER_EMISSION_ENABLE was spot on. Exactly what I needed. Works perfectly! Really appreciate it. Anthony

Hi Ilia, Thanks a lot for the quick and clear reply! That makes sense. I had a feeling it might be a limitation of the current API. I’ll definitely follow up with the Redshift team on their forum to confirm whether there’s any workaround or future support planned for accessing those fields. Appreciate your help and the reference to the related thread! Cheers, Anthony

Hi @d_keith, I would kindly ask you to check our Support Procedures, namely the "How To Ask Questions" paragraph: Singular Question: The initial posting of a support topic must contain a singular question. Do not ask ten things at once, that makes it extremely hard to answer topics. Break up your questions into multiple topics. Here you effectively have 4 different questions about Asset Browser, and these are candidates for 4 different threads on the forum. In your further postings please try to follow the aforementioned rules. Regarding your questions: Should I be able to mount a directory and have it auto-create a DB? Mounting database is effectively executing the AssetDataBasesInterface.SetDatabases. It has nothing to do with creating database neither semantically, nor is this mentioned in the docu. If you need to create repository, please use maxon.AssetInterface.CreateRepositoryFromUrl(), it will scan the directory for being already a database and create proper dir structure if it's not. Any idea why I need to re-try creating the Repo for it to work? If you face any errors in the script, please always attach at least the error message! In this case I assume you receive the following error, when executing the maxon.AssetRepositoryTypes.AssetDatabase() for the first time after Cinema 4D started. Looks like a bug to me, I've created a bug report for that (ITEM#585831). The error message: Traceback (most recent call last): File "console", line 1, in <module> File "C:\Program Files\Maxon Cinema 4D 2025\resource\modules\python\libs\python311\maxon\interface.py", line 5049, in __call__ self._cachedObj.R = _maxon_mapping.GetAssociatedDataType(dt) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Exception: unable to find datatype As a workaround you can just execute the following line first in your main(): maxon.AssetRepositoryTypes.AssetDatabase() ... about multiple DBs ... You're giving your databases unique IDs with the line repo_id = maxon.AssetInterface.MakeUuid(str(url), True). If you need them to be the same, just pick one instead, e.g. repo_id = maxon.Id('net.maxon.sdk.cool.things.repo') ... revealing assets doesn't work... I've created a bug report for that, as it looks like a bug with refreshing in the Asset Browser. As a workaround you can reload databases and reopen the AB before reveling your assets, e.g.: def RepenAssetBrowser(): CID_ASSET_BROWSER = 1054225 # Close the Asset Browser if it's alredy opened if c4d.IsCommandChecked(CID_ASSET_BROWSER): c4d.CallCommand(CID_ASSET_BROWSER) # Open again c4d.CallCommand(CID_ASSET_BROWSER) def main(): # ... # assets = [] # ... # assets.append(asset) # ... maxon.AssetDataBasesInterface.ReloadAssetRepositories(True) RepenAssetBrowser() maxon.AssetManagerInterface.RevealAsset(assets) Cheers, Ilia

Hey, Node attributes are things that are directly present on a GraphNode. You could also call them fields, because a GraphNode like many things in our API has qualities of a DataDictionay, i.e., you can write values over keys into it, just like for Python's own dict. Such node attributes (for true nodes) are then rendered out quite similarly to port values in the Attribute Manager but they are fundamentally different from ports, as users cannot drive their value with a connection, i.e., the value of a port of another node. And a port also always requires another GraphNode attached to the true node¹ for which they are a port, while the attribute sits directly on the true node. An attribute, e.g., the name of a node, will also never show up in the node representation in the graph. In the screen below I for example right clicked on the RS Reference node and invoked Add Input > All; but things like Name, Color, Show Preview etc. are alle not listed. [image: 1744368637847-174097cf-d777-49d2-b0ea-0057c8474a5e-image.png] That is because they are all attributes and not ports. There is unfortunately no absolute rule like 'everything in Basic is attributes and everything else is ports'. While it holds (for now) true that everything in Basic is an attribute, especially Redshift also puts attributes into other tabs. They usually only appear in more complex scenarios when dealing with port bundles and variadic ports, but they exist. And just for clarity, attributes do not only exist on nodes that are what our API calls 'true nodes'¹, but also on other GraphNode types, e.g., a GraphNode representing a port. It is just that they are usually not rendered out to the GUI there and more of an internal nature (nodes have a lot of internal attributes). Cheers, Ferdinand ¹ GraphNode instances that represent what the end user would consider a 'node', e.g., the RS Reference node, and with that excluding GraphNode instances that for example represent an input port.

Ah, super! thank you.

@ferdinand said in SAVEDOCUMENTFLAGS_AUTOSAVE still added to the recent file list?: But please provide instructions on how to use your code when required in the future. oh shit, i'm so sorry. you're right. completly missed this one. ... and of cause thanks for the explaination / clarification.

@i_mazlov Thanks

@ferdinand said in How to simulate a drag behavior with UA?: All it it does when the users starts to drag, according to Maxime, is inject the asset object into the document, make sure there is no object selected and then enable the place tool (and probably set the mouse cursor) This is my solution in my mind, definitely take a try after work.

Fantastic @i_mazlov ! Both issues are solved, thank you so much ! Cheers, Flavio Diniz

Love the mxutils and GeDialog Changes, I use these features almost every time, thank you for having a more refined official version. Thank you to the SDK team for their work achievements Cheers~ DunHou

hi, i came up with this now... def hasGenFlag(op): description = op.GetDescription(c4d.DESCFLAGS_DESC_NONE) bc = description.GetParameter(c4d.ID_BASEOBJECT_GENERATOR_FLAG) return not bc[c4d.DESC_HIDE] if bc else False also its clear that "Generator" is a wide definition which doesn't match the Green Checkmark / Enabled GUI Element. in this sense the topic title is wrong bc i was just searching for a way to distinct objects having this GUI element from others which don't. (i can't change the topic title, i guess)

@i_mazlov Thanks,it works!
