btw, same on windows

Hey @Dimitris_Derm., The example py_msc_licensing shows you how to change the icon of a node at runtime. The example uses this to change the icon of unlicensed nodes and the trick is to listen for the message MSG_GETCUSTOMICON. The example py_obj_assetcontainer shows you how to place icons in cycles (Cinema slang for drop downs). The trick is to set the label of the cycle item to "{Label}&i{IconID}&", e.g., "Cube&i5159&" would display the cube icon next to the word "Cube", because 5159 is the cube object icon id. You can do this both in resource files and dynamically as the example does it. Cheers, Ferdinand

Hi @ferdinand , Yes, I do need the dimension overlay to coexist with another active tool. The plugin is mainly intended to help adjust objects to realistic dimensions and proportions. When precise dimensions are not required, the overlay helps me quickly resize and place objects in the scene. Once that is done, I can turn off the dimension overlay. The plugin can be enabled or disabled directly and includes some settings, with usage similar to the Symmetry tool. Inactive objects do not display dimension information, and grouped objects are measured as a whole, so the viewport does not become a sea of dimension annotations . Cheers, Anlv

Hello @hey2495, Welcome to the Maxon developers forum and its community, it is great to have you with us! Getting Started Before creating your next postings, we would recommend making yourself accustomed with our forum and support procedures. You did not do anything wrong, we point all new users to these rules. Forum Overview: Provides a broad overview of the fundamental structure and rules of this forum, such as the purpose of the different sub-forums or the fact that we will ban users who engage in hate speech or harassment. Support Procedures: Provides a more in detail overview of how we provide technical support for APIs here. This topic will tell you how to ask good questions and limits of our technical support. Forum Features: Provides an overview of the technical features of this forum, such as Markdown markup or file uploads. It is strongly recommended to read the first two topics carefully, especially the section Support Procedures: How to Ask Questions. About your First Question I would try closing the file into which you imported the Alembic file. I just checked it, when I import any Alembic file, Cinema holds a lock onto it while the file into which you imported is still open. That seems to be an Alembic specific behaviour, not to say a bug. But it should be avoidable by simply cloning or merging the imported document, so that you can close the import document. I will give the exchange team a heads up on this. Cheers, Ferdinand

Man this saved me so much time too. Thank you.

First of all, you should open new topics for new questions, as one otherwise tends to derail old topics, which makes it hard to for others to follow things later. I forked your topic. And I also do not quite understand what your question is. GetClosestMeshPrimitive returns you the primitive type via primInfo. When you only want to get the closest point on a mesh, I would build a KD-Tree for its vertices. You then get the closest vertex and its index for your point p. Then you orthogonally project p onto the polygons attached to that vertex (via cinema:: Neighbor). Then you chose the closest point. We have this Python example for KDTree and I also used Neighbor there. Building a KD-tree or just brute forcing it depends a bit on how often you want to do it. For just a handful of points, brute forcing it is usually faster. I am sure you can also do this with DistanceQueryInterface and the uvw coordinate returned in the PrimitiveInformation, but all that extra work where you have to deal with all the primitive types seems like more work than it is worth. And when you want to do this in a generator (by the looks of your screens), using a manual KDTree approach will make it easier to parallelize it effectively and make it go zoom zoom instead of computing all that extra data. Cheers, Ferdinand

Thank you all for your answers. Will test this.

About your Question We have noted your feedback and we are aware of some of the shortcomings of the current API. Subtool and folder management are high on the list of the use cases we plan to cover in a future API update. At the moment though, we don't have a set date for releasing a new version of the API. Please, let us know if you identify more areas of improvement. Regards, Davide

Thank you @ferdinand for looking into this, as well as bumping the request to the RS developers. Any update on this would be appreciated! Thanks.

Hey, yes it is. The trick is c4d.LV_CHECKBOX_HIDE, the relevant bits happen in GetDropDownMenu.

You likely have to call UpdateOcioColorSpaces, just follow the example. There is btw no guarantee at all that DOCUMENT_COLOR_MANAGEMENT entails a render space of ACEScg. That is just the default, the user could have changed that. I am also not sure what all that RDATA_IMAGECOLORPROFILE code is meant to do. It depends a bit on what your plugin does and what self.IsForceLinear is meant to express. Only so much: An OCIO document does not necessarily entail a bitmap with a non-linear color profile, and OCIO also does not mean that the bitmap has to be 32bit. You are however missing UNDOTYPE_PRIVATE_DOCUMENTDATA undo management for setting the color management.

@ferdinand Okay, I will handle the plugins and files at an appropriate time.Thanks reply

@ferdinand Thanks for your detailed explanation. Although the precision conversion leading to value changes is not an error, it is indeed not what we want in terms of the results. For example, when dealing with the weight of some points, using SetWeightMap() will update the weights of other points, resulting in numerical changes. Only using SetWeight() can at least ensure that the weights of unoperated points do not undergo numerical changes (but using SetWeight() must tolerate the print warnings outputted by the console)

Hi, @ferdinand and @Anlv this is most awesome! All way beyond my capablities so thanks a lot for the scripts!

Hey @Kantronin, you might want to look at geometry_polgyon_edges_2024.0.py, it should answer all your questions. The TLDR is: full-edge maps as you hint at in your posting do exist in Cinema via helper functions, but they are often also not very useful. Internally, Cinema is operating as any other DCC application with the concept of what is often called a "half-edge" data structure. So, when you have the two polygons A and B: a---b---e | A | B | d---c---f Which share an edge over the vertices b and c, this is actually two edges and not one, due to how normals work. For both polygons to have a normal facing in the same direction, they must have opposite winding orders, which means that the edge b-c is actually two edges: b->c and c->b. So, A could for example index the edge as bc, and B as cb. The example goes into more detail with this. Cheers, Ferdinand

@ferdinand Thanks for your detailed explanation and the implementation of the sorting function. It's very helpful！
