Yes, the situation you described is exactly what we need.

We released v4.0 without mb support in C4D for the new 4D characters (in regular rigged and ambient characters it works ok) but we could introduce it in a 4.1 or something like that.

@zipit said in Check if GetVirtualObjects is called for Motion Blur:

n that. What I meant was: Listen to the message and once you retrieved it (and determined that this is an animation rendering that contains a motion blur), you can set a flag in the instance of your plugin object that tells GVO that this instance should be constructed as motion blur safe. And since you are then in a rendering document, that will have no impact on the editor behavior of your object. The made up symbol was just an attempt on trying to convey that without writing a wall of text ;)

I disabled it by using a motion blur tag, btw I was speaking about these characters, unfortunately since I cannot get that preframe signal c4d won't support motion blur https://vimeo.com/397454524

@zipit sorry I didn't find anything related to ALWAYS_YIELD_MOTIONBLUR_SAFE_GEOMETRY :\

@zipit MSG_MULTI_RENDERNOTIFICATION was a nice tip but in our case, it only works for still since that MSG is triggered only once in an animation, the same MSG if it could be called once per frame in an animation could be just perfect.

Hi Adam I think that probably I've posted with my personal account right now but I've been on the forums for a while, I'm the developer of the Anima for c4d plugin (and I know Riccardo for a long time since I was on the development team of Thea)

My question is tricky and related to Anima (the crowd system) plugin.

We have a new kind of models that could change its topology with the time, also we have a fallback that allows me to retrieve the non-changing-topology mesh for motion blur. Your suggestion works nice if the mb call only less than one frame but fails for bigger ranges since it could give us an integer frame and I'll return a different topology.

I'm still wondering if there is any other way...

Regards, Víctor

In other software packages they have 4 callbacks PRERENDER, PRERENDER_FRAME, POSTRENDER_FRAME and POSTRENDER.

Obviously if between PRERENDER_FRAME and POSTRENDER_FRAME GetVirtualObjects is called more than once we know that the first one is the actual call and the others are just called for effects like Motion Blur.

Is there something similar or any other way to get this information in C4D ?

Thank you in advance

I'm working on a plugin that needs to free some resources as well as closing a TCP connection, unfortunatly you cannot rely on C4DPL_ENDPROGRAM since if your scene is not saved and try to close c4d that signal is trigged but you still can click on Cancel so the app is not closed and you could have freed your resources.

Any thought on this? Thank you in advance.

@r_gigante It was about updating an object during the render process but I used a different aproach just by sending the object's doc to that function so I think it could be solved already.

I'm using BaseDocument
*doc = GetActiveDocument();
to get the document we are using and

const UnitScaleData docScaleData = (const UnitScaleData)doc->GetDataInstance()->GetCustomDataType(DOCUMENT_DOCUNIT, CUSTOMDATATYPE_UNITSCALE);
Float otherScale = 1.0f;
docScaleData->GetUnitScale(otherScale, docunit);

to get the units in the scene, unfortunatly GetActiveDocument() returns a doc named "Untitled 1" in Team Render rendering process so I cannot get the scene units.

Is there any way to get the current scene or units during a Team Render rendering session?

@y_puech said in ParseTupleAndKeywords in R20:

Hi Victor,

There's a logic error in the code you posted from the first post. The condition for R20 if (str.IsEmpty()!=false) returns false if the string has content.
It makes more sense to call IsPopulated() for the R20 code instead of IsEmpty().

You are right, thank you!!!
