Hello @ferdinand ! Thanks for answer it is very clear, i will use virtual resolution from now on

Hey Kent, it depends a bit on the context. Generally, yes, flags and parameters passed to a BaseBitmap are piped through to the underlying ImageRef. But as I hinted at with the TIF settings for BaseBitmap::Save, some stuff is also ignored. For fundamental stuff like initializing a bitmap with a channel depth, color format, etc., I am not aware of cases where flags are being ignored. But as I wrote in my pseudocode example, the exact nature of the BaseBitmap::GetImageRef is also quite important. My very high level advice would be, use the Maxon Image API directly for simple things like loading, color converting, or saving an image, but avoiding it for complex tasks like for example assembling a multi layer image or drawing (not possible at all in the public API apart from 'dumb' pixel by pixel drawing). The problem with this is that when you must have a BaseBitmap output. Because while you can get an ImageRef from a BaseBitmap instance, there is no 'sane' public way to construct a BaseBitmap from an ImageRef you can of course copy over the buffer manually (not so sane) and there is a private way to do this but has its pitfalls (but is possible to do with the public API). As I said, I would invite you to reach out to us with some code and a concrete use case when you get stuck, I will then be able able to help you specifically. Cheers, Ferdinand PS: We recently dropped the term 'classic API' in favour of 'Cinema API'. We also capitalize now 'Maxon API'. Just saying this for clarity.

Hi Ilia, Thank you very much, I was not aware of that! Cheers!

Oh, my bad, I did overlook that you flagged this as S26. Yes, mxutils is a 2024+ feature. I used it here to carry out type checks, e.g., that a document or bitmap are not null/none. The code will run without them, but it will fail more gracefully with these checks. You could replace these calls with manual checks: bmp: c4d.bitmaps.BaseBitmap = c4d.bitmaps.MultipassBitmap( int(rData[c4d.RDATA_XRES]), int(rData[c4d.RDATA_YRES]), c4d.COLORMODE_RGB)) if bmp is None: # or more precise: if not isinstance(bmp, c4d.bitmaps.BaseBitmap) ... raise MemoryError("Failed to allocate bitmap.") Cheers, Ferdinand

And that's good to know about using GetMl() over Get Mg(), mainly for the performance reasons if I understood correctly.

Thank you so much, this was very helpful to learn. All the best.

Hey @lednevandrey, without wanting to be rude, I really struggle with understanding what you want to convey. Material[c4d.TEXTURETAG_PROJECTION] = c4d.TEXTURETAG_PROJECTION_UVW does not work because Python is case sensitive and you gave your BaseMaterial instance the symbol material. So, Python is complaining about that. But as said before, a material, i.e., BaseMaterial is not the right place to set the projection. It is the counter part to the thing you see in the Material Manager of Cinema 4D and has no projection. The projection is set in the Material Tag, which slightly confusingly is called TextureTag in the API. Cheers, Ferdinand """Assigns the first material in the document to the selected object and sets its projection to UVW. """ import c4d import mxutils doc: c4d.documents.BaseDocument # The currently active document. op: c4d.BaseObject | None # The primary selected object in `doc`. Can be `None`. def main() -> None: """Called by Cinema 4D when the script is being executed. """ if not op: raise ValueError("Please select an object.") # Get the first material in the document. material: c4d.BaseMaterial = doc.GetFirstMaterial() if not material: raise ValueError("No materials found in the document.") # Get the first existing texture tag on #op or create a new one when none exists. tag: c4d.BaseTag = op.GetTag(c4d.Ttexture) or op.MakeTag(c4d.Ttexture) if not tag: raise ValueError("Failed to get or create a texture tag.") # Set the material and projection. tag[c4d.TEXTURETAG_MATERIAL] = material tag[c4d.TEXTURETAG_PROJECTION] = c4d.TEXTURETAG_PROJECTION_UVW # Update the Cinema 4D UI. c4d.EventAdd() if __name__ == '__main__': main()

Great to hear that you found your solution! Do not hesitate to ask more questions when you run into problems while exploring our Python API. But just as a heads up, we prefer users opening new topics for new questions. For details see the Support Procedures linked above. Cheers, Ferdinand

Wow @m_adam , thanks for that, I'll check this after work!

Hey BigRoy, sadly it's still impossible, I will start the discussion again, thanks for the reminder. Cheers, Maxime.

I was just looking for the exact same thing and would second the need for these 3 hooks without the need for a Python Generator object. It would make the pipeline integration of C4D much more straightforward. @m_adam

Hi @datamilch, you can use the EVMSG_CHANGE message as a trigger to check your objects for changes. The timer approach might seem imprecise from the first glance, but can actually be used, I don't think there're any significant reasons against it. Additionally, the recent change was made to make BaseList2D being hashable. This effectively means you can operate with your objects in a dict. The python tag approach is the least efficient, although would still work, yes. You're saying your GeDialog plugin uses "mostly the ideantical userdata". If it was "identical", you could potentially use c4d.gui.DescriptionCustomGui with the SetObject function to make it point to your object. This way you can avoid hassling around all the data sync, because it is all handled as a built-in functionality of this class. This is how the attribute manager effectively works, or the Active Object Dialog as well. For your further postings please follow our guidelines on How to Ask Questions, namely: Please consolidate your questions into a singular posting by editing your last posting Cheers, Ilia

Alright! Thats a sweet improvement. Okay no worries we'd already moved to the method you described! Does this change back propagate to earlier versions like 2023?

Hi @César-Vonc , Cinema 4D uses OS clipboard to some extent, namely as you can see from the CLIPBOARDTYPE enum there's text and image clipboard options. For other Copy&Paste functions the built-in clipboard system is used, hence the OS clipboard stays untouched. Cheers, Ilia

Hi @John_Do, Please note that this forum is for the public APIs of Maxon products related topics. We unfortunately cannot help with the end user issues. Please ask your end user questions in our Support Center. This and also other important considerations are mentioned in the Scope of Support part of our Support Procedures. With that's said, your question gives a fuzzy impression on what exactly you're asking about. Namely, you're talking (presumably) about the CopyToClipboard() function, but then also claim the issue is not there, rather when you paste this bitmap in the PV. Could you please share some code snippet, which highlights the issue, especially the pasting part, which seem to not work as expected. Please also make sure you've setup the Picture Viewer's View Transform to meet your needs. In our internal bug tracking system I'm also seeing 2 issues that we already keep track of: A-B comparison issue that was just recently fixed and is not yet released Picture Viewer issue with OCIO enabled when using EXR files However, none of these seem to be specifically related to your case. If you're still having this issue and it is not related to our SDK, I would kindly ask you to reach out to our Support Center. Cheers, Ilia

@i_mazlov Thanks much for explanation.

I have moved this topic into General Talk for now. When this is indeed an end user question we must ask you to use our Support Center, the developer forum is not the right place for end user questions. When this is a development question, then please line out the current code you have and provide a meaningful problem description. Cheers, Ferdinand

@i_mazlov Thanks! makes sens. seems i only used the forgiving commands until now. the code is run in a python generator. so by returning the object, it will be inserted into the scene.

hi @i_mazlov, ok, good to know. i also tried to insert the thicken generator into a temp_doc, activating the selections and executing passes. but that didn't work either.

@i_mazlov Thank you for your reply. That was very helpful!
