          Hi community!

          Th renderEngine library has been updated to the 1.0.4 version, there are some re-write functions and may not incompatible with older versions,see the main changes as follows:

          • rename all node & material functions to Capitalize style.
          • remove transaction in node_helper, use it in the final scripts.
          • organize the functions in node_helper with comments ( node\port\wire\util )
          • add some functions to check node or port info, like if it is connected , see the README.
          • add a InserShader function to create a shader into a wire.
          • re-write RemoveConnection in node_helper and support one argument(port) to remove connection.
          • see the Version & Updates

          Cheers~

            Hi community!

            Since my last post, I had some updates and fix to this library.

            And the following picture shows the new node functions added to my Render Flow plugin based on the use of this library within few lines( just the node context ).

            Have fun with it.

            Cheers~

                Wow ... good stuff
                My c4d Programing slowed down this year, but this might be something I want to use some day ...

                    Hi community!

                    New versions here!

                    I had change the name from renderEngine to Renderer, and also changed the main structure. see more in the very first of this topic. (renderEngine had been move to versions folder, if you still interested.)

                    This version is way more organized and user-friendly, you can use few lines of code to do something normal work, find an example below:

                        Hi community!

                        Here is a little example of how we modify scene objects in Arnold, find more examples in the top.

                        We want:

                        • Add a Arnold Sky with hdr
                        • Add a gobo light with a node-base gobo material, and a IES light
                        • Add a cube and add a custom mask to the driver
                        • Add a Scatter with custom instance shapes
                        • Auto export proxy with a BaseObject and load back the ass file (need to save project first)

                        Have fun with it😊

                        Cheers~

                          Hi community!

                          Another little update, as we didn't have DataDescriptionDatabaseInterface as @ferdinand said in How can we get the default port of a GraphNode?

                          I add a ConverterPorts to Renderer, we can use this to get the "default " port of a node until the DataDescriptionDatabaseInterface is valid in python.

                          Note: It can only provide the str data of the port and it's not 100% rigorous

                          Cheers~

                            Hi community!

                            I had add a basic support to V-Ray and Corona to fit the basic PBR usage, no Scene and AOV yet (AOV seems I can not get them in python, if someone knows where it stores, please let me know that).

                            Cheers~

                              Hi regarding Vray, I once wrote this plugin that have the duty to create ObjectId passes.
                              I did not try it since age, but previously Vray AOV where stored within a branch on the Render Engine.

                              I don't have vray installed currently, but I guess if you compile the C++ SDK, with the help of the C++ SDK Active Object Example it should be trivial to inspect a Vray scene and find these AOV.

                              Cheers,

                                Thanks for @m_adam prompt, I had add a AOV to Vray as same as other renderers, see a basic example here, hope it can help 😊

                                Cheer~

                                  Hi again,

                                  Also another Corona AOV example here .

                                  Finally preliminarily implemented using this library to approximate the operation of the renderer in Cinema 4D .

                                  The learning process was very enjoyable, hope you also have fun with it ✌

                                  Cheers~

                                    Hi community!

                                    New Updates here :

                                    • Fix some Octane and Corona functions (base on layer)
                                    • Add MaterialMaker and PBRPackage

                                    PBRPackage means a suite of pbr textures, like a stone texture pack form PolyHaven or Megascan, you can provide the folder and the name to get the slot they should be:

                                    • we have a texture pack named Rock Stone 01
                                    • this package had some textures in D:/myTextures ,like Rock Stone 01_albedo.jpg/Rock Stone 01_Normal.png/Rock Stone 01_disp.exr.
                                    • we can provide the folder like D:/myTextures and its name like Rock Stone 01
                                    • then we get textures in a dictionary
                                    data = {"diffuse": Rock Stone 01_albedo.jpg,
                                                  "normal": Rock Stone 01_Normal.jpg,
                                                  "displacement": Rock Stone 01_disp.jpg,
                                                  etc...
                                    }
                                    

                                    Material Maker can easily add pbr materials from a package, and also you can use it with individuals textures.

                                    But all of this build with this library, so only node materials on Redshift/Arnold/Vray, Octane and Corona is supported by thier own logics.

                                    Cheers~

                                      Hi community!

                                      Add Basic CentiLeo Material support, also with ConvertPorts data, This a "new" GPU Renderer and in active development. I am very interested in it.

                                      Not add AOV due to still being in the early stages of development, waiting for this.

                                      Cheers~
