According to the documentation, the midpoint of orthogonal projections is set with the "Offset" property.

See CameraObject Manual.

According to the documentation, you can use GetIcon().

See NodeData::Message() Manual.

Why not use IoShowInOS()? (didn't test it on macOS though).

maxon::Url url { "file:///D:/_tests/test.html"_s };
url.IoShowInOS(maxon::IOSHOWINOSFLAGS::OPEN_IN_EXPLORER) iferr_ignore("");

See Url Manual.

According to the documentation: transparency defines how much color the thing has: "A transparency texture is similar to a photographic slide: Red parts of the slide allow only red light to pass through; white parts allow all light through. With black, no light can pass through the slide."

Alpha defines if there is a thing at all: "An alpha channel enables you to use an image to mask out areas of the material, allowing any background to show through."

@Cairyn said in What is the max parameter in BaseSelect.GetRange() really for?:

I would interpret that as assurance that any value we get returned is smaller than max. So if there is a segment (1,5) and max = 3, then we'd get (1,3) back. (I can't for the life of me think of a reason why I would want that, but hey.)

Simple: interpret an element number as an index. You don't want that index to be out of range.

If you have a list of n elements and a BaseSelect object to store which elements of that list are "selected", you want to ensure that an index provided by GetRange() is a valid index of that list.

Why there is an issue with Python I don't know.

As you can read in the documentation, the custom GUI for SHADERLINK is TexBoxGui, which has the custom GUI ID CUSTOMGUI_TEXBOX.

See also Custom GUI Elements.

Normal data is stored in a Normal tag. See NormalTag Manual.

So you can create a (new) normal tag and store any new normal data you like.

If you look around the forum you will find threads showing how to do that in Python, e.g. Handling direction of the normal tag.

Just FYI: To calculate the normal of a single CPolygon, there is CalcFaceNormal().

See also NormalTag Manual.

What version of Cinema 4D are you using? GeFree() is pretty outdated.

Is BaseDocument.GetChanged() what you want? See Changed Mode.

The Cinema 4D C++ SDK is not the same as the Cineware SDK.

The Cinema 4D C++ SDK is included in every distribution of Cinema 4D.

The Maxon Cineware SDK can be downloaded from the developers' blog, as you already did, according to your previous posts.

You could write a standalone C++ application that uses the Cineware SDK and the FBX SDK.

However: The C4D file format knows mathematical, procedural objects, e.g. procedural cubes, spheres, or other shapes. And you cannot assume that there are perfect counterparts in the FBX format.

So what do you want to do with such C4D specific object types?

The only proper way of handling this is when a user exports a C4D scene optimized for Cineware, so that polygon and animation caches are build.

@liushu said in how can I convert a c4d file to fbx format:

2 . I can download c++ sdk. I am c++ programmer.
I do it according to https://medium.com/@antoinefortin_64750/how-to-setup-cinema4d-and-melange-c-sdk-924110725c01

This is NOT the C++ SDK. The C++ SDK is included in your installation of Cinema 4D; you find the C++ documentation online.

What you are looking at is some random online source talking about the Cineware SDK (formerly known as Melange), which is something else. See Cineware.

"AttributeError: 'NoneType' object has no attribute 'Connect'

means that the variable node1out is a NoneType; it is not what you think it is. That means that node1.AddPort() has returned None.

Why AddPort() has returned None, I don't know. I can only speculate that one has to construct a more complex DescID handling MG_GRID_RESOLUTION.

I don't know about your code. But a field is typically sampled using the "Sample" functions. There is an example using SampleListSimple().

BaseDocument::InsertObject() has the argument checknames, used to perform that unique name creation. Strangely, the option is marked as deprecated in the C++ API, but not the Python API.

See Checknames option.

In computer science, there are vertex shaders, geometry shaders, and tesselation shaders, which change an object's vertices or the object's geometry.

Cinema 4D's ShaderData is only a pixel (or fragment) shader. AFAIK, there are no vertex, geometry, or tesselation shaders in C4D.

Parameter units are defined with the c4d.DESC_UNITproperty. See Description Settings Manual.

To change the properties of an existing parameter, one would have to translate this code to Python: Description Manual.

@WickedP said in Render to PV / Video Post plugin:

• can I update the PV progress bar manually?

You can set render process settings using BASEBITMAP_DATA parameters: BaseBitmap Manual.

• am I suppose to use GetDDescription() to draw the options in the render settings dialog (mine isn't showing anything)?

You can use a standard parameter description resource as usual. You find a dozen examples in your installation or in the SDK examples.

What is a "draw plugin"?

A VideoPostData plugin is used to do two things: creating a video post (that does something with the rendered image), or implementing a render engine, that renders the scene.

If you want Cinema to skip rendering the scene, you are creating a de-facto render engine.

Calling RegisterVideoPostPlugin(), you can set PLUGINFLAG_VIDEOPOST_ISRENDERER to make that clear.

You can call VolumeData::SkipRenderProcess() to tell Cinema not to render the scene; I'm not sure when the correct time is to call that. But you find some threads in this forum discussin that function.

GetParam() and SetParam() have nothing to do with strength; they are used to set arbitrary overwritten object parameters. See CAMorphNode Manual.

The DescID of the morph's "Strength" value is obtained with GetMorphID(), see CAPoseMorphTag Manual.
