Here you go: https://github.com/NiklasRosenstein/py-localimport
That helper is also available as a minified version.

You have to update the document each frame with ExecutePasses()
In your for loop, simply add doc.ExecutePasses(None, True, True, False, c4d.BUILDFLAGS_NONE) as the first method call. (Adjust parameters to your needs.)

As far as I remember, Viewport drawing is handled in Draw() method.

Did you try my proposed fix? ;)

This happens because tools that will be called twice in short succession gain focus in the C4D layout. Therefore your Dialog loses focus as the Move tool is bound toE.
I don't kbnow exactly how to prevent that behavior, but there should be some message that can be processed. SDK team will be more of help here.

edit: Easy fix: return c4d.NOTOK after your print statement. That consumes the message and does not call the base function, so Cinema simply does not get notified of the event.

Are both header files or is the upper one a cpp file?
Also, do the errors com from Intellisense or is it a style check/compilation error?

If the LLVM convention is used, the error is correct. LLVM namespace formatting conventions don't use any intentaion. You might be a able to fix this by ignoring this error explicitly.
It also might be caused by a bug in XCode.

Sure, your statement was correct. That's why I mentioned the possible misunderstanding here. That's on my side (as usual :)).
You posts are invavuable for all of us, so I'd be damned if I'm going to accuse you of being wrong. :P

Sure. The reason why I know that is, I do it occassionally. :)
Niklas answered me that question a while ago: https://plugincafe.maxon.net/topic/9400/12588_multiple-nodedata-descriptions-solved/2

But it seems, there's a misunderstanding here. Multiple plugin IDs cannot be registered. But you can create a composite plugin with different descriptions.
I usually do that with NodeData plugins.

Best,
Robert

@ferdinand said in Purely dynamic description for shader?:

1. So you talk about multiple descriptions, but a singular plugin, which I do not understand. No matter what you do, you can only register a plugin once and provide a singular description for it. You cannot register the same plugin with multiple descriptions.

I have to disagree here. The Cinema 4D Multipasses for example are implemented in exactly this way. ( by registering multiple descriptions though)

Hello,

I noticed that when using a GeListHead for storing custom BaseList2D items leads to a crash when TreeViewFunctions' SetName is called.
Is this a known bug/behavior?
If not, what did I do wrong? ;)

Here's a minimal example. Try to rename any ListItem with Double-Click -> Freeze.
On R21 I did some more debugging and it turned out that obj in SetName() is of type long.
