Hello!
My plugin is conflicting with Redshift 3.0.20. Cinema 4D loads infinitely until i disable Redshift, then it loads and plugin works.

Commandline.exe doesn't show any error, each plugin loaded.
Project was compiled with Visual Studio 2017 v141 std17 in Release, Windows 10. Plugin has it's own unique ID from plugincafe.
How can i find out where conflicting part is?

Hello! I have a problem with my deformer plugin.
Plugin not only deforms shape of an object, but also adds new polygons and points to it.
Problem appears when i try to use isoparms mode.
What i figured out:
Problem was in SendModelingCommand(). It was solved by making new document, executing passes and copy to original object.

Bool DeformerPlugin::Disconnect(BaseObject* main, BaseThread* thread) {
	BaseSelect* select = ToPoly(main)->GetPolygonS();
	select->DeselectAll();
	AutoAlloc<BaseDocument> basedocBuffer;
	BaseObject* clonedOp = (BaseObject*)main->GetClone(COPYFLAGS::NONE, nullptr);
	basedocBuffer->InsertObject(clonedOp, nullptr, nullptr);
	basedocBuffer->ExecutePasses(thread, true, true, true, BUILDFLAGS::INTERNALRENDERER);
	ModelingCommandData mcd;
	BaseContainer bc;
	bc.SetData(MDATA_DISCONNECT_PRESERVEGROUPS, false);
	mcd.doc = clonedOp->GetDocument();
	mcd.op = clonedOp;
	mcd.mode = MODELINGCOMMANDMODE::POLYGONSELECTION;
	mcd.flags = MODELINGCOMMANDFLAGS::NONE;
	mcd.bc = &bc;

	if (!SendModelingCommand(MCOMMAND_DISCONNECT, mcd)) {
		ApplicationOutput("Disconnect error.");
		return false;
	}
	clonedOp->CopyTo(main, COPYFLAGS::NONE, nullptr);
	clonedOp->CopyMatrixTo(main);
	clonedOp->CopyTagsTo(main, NOTOK, NOTOK, NOTOK, nullptr);
	return true;
}

I should mention that plugin works well with polygon mesh objects and problem appears only with generator objects in isoparm mode.
I guess problem is in Isoparm lines. I've tried to use BUILDFLAGS::ISOPARMS. I cannot use it with non-generator plugin. But i saw few plugins that change count of polygons and still work good. And due to my logic in code i cannot change plugin type to generator.

Although creating a temporary document has been a solution, it still doesn't work good. Cinema4d crash appears randomly while i'm testing it. Usually it happens when i reduce amount of detail, i guess it is something with caches.

What isoparms even are? Why should i use it and how to prevent cinema from crash?
And what about SetIsoparm()? Can i use it in deformer plugin somehow? And should i?

@m_adam Maybe i'm little misunderstood you. I meant not exactly third case. But a case, when you start holding your mouse at empty space and selecting objects with outcoming rectangle.

@m_adam Thanks for your help. That made things clear.

@m_adam Unfortunately, we are looking for real-time performance. RenderDocument is fast only on light projects.
We are also looking for a workaround.
We are trying to create plugin which tracks switching between documents. What is the most efficient way to catch last image of document viewport before switching the document? There is MSG_DOCUMENTINFO_TYPE_SETACTIVE, but as i understand, it will be too late to get viewport image after that event.

@m_adam Thanks for your reply.
As many as there opened documents.
Context is CommandData.

Hello! I asked about GetViewportImage() in this topic few days ago. Code worked as it should, but it seems like it only gets image from active document, even tho BaseDraw is different.
Here is my code.

BaseDocument* doc = GetFirstDocument();
		while (doc) {
			BaseDraw* bd = doc->GetActiveBaseDraw();
			if (!bd) {
				doc = doc->GetNext();
				continue;
			}
	                AutoAlloc<BaseBitmap> bitmap;
			// Get the viewport image from the viewport renderer
			maxon::ImageRef img;
			bd->GetViewportImage(img);


			if (img == nullptr) {
				doc = doc->GetNext();
				continue;
			}

			// Transform ImageRef to BaseBitmap in order to show it in the PictureViewer
			const Int w = img.GetWidth();
			const Int h = img.GetHeight();
			


			maxon::PixelFormat rgbf = img.GetPixelFormat();
			Int32 bitsPerColor = (Int32)(rgbf.GetBitsPerPixel().Get() / rgbf.GetChannelCount());
			bitmap->Init((Int32)w, (Int32)h, bitsPerColor == 32 ? 96 : 32);

			maxon::BaseArray<UChar> line;
			line.Resize(w * rgbf.GetBitsPerPixel().GetBytes()).GetValue();

			maxon::PixelMutableBuffer imageBuffer(line.GetFirst(), rgbf.GetBitsPerPixel());
			maxon::GetPixelHandlerStruct getpixel = img.GetPixelHandler(rgbf, rgbf.GetChannelOffsets(), maxon::ColorProfile(), maxon::GETPIXELHANDLERFLAGS::NONE, nullptr).GetValue();

			for (Int y = 0; y < h; y++)
			{
				getpixel.GetPixel(maxon::ImagePos(0, y, w), imageBuffer, maxon::GETPIXELFLAGS::NONE).GetValue();
				bitmap->SetPixelCnt(0, (Int32)y, (Int32)w, line.GetFirst(), (Int32)rgbf.GetBitsPerPixel().GetBytes(), bitsPerColor == 32 ? COLORMODE::RGBf : COLORMODE::RGB, PIXELCNT::NONE);
			}
	                ShowBitmap(bitmap);
			doc = doc->GetNext();
		}

Each showed bitmap contains only active document viewport.
I also tried to switch document with SetActiveDocument() and then call DrawViews() before getting viewport image, but that didnt work.
Is there a way to get viewpirt image of inactive documents?

@m_magalhaes Thanks a lot! That makes things clear.

Hello! In R23 we got an interesting feature to play with, but there is not much of an info about how to use it properly. Im talking about BaseDraw::GetViewportImage().

This is what i tried.

AutoAlloc<BaseBitmap> bmp;
maxon::ImageRef imgr = maxon::ImageClasses::IMAGE().Create() iferr_return;
const maxon::PixelFormat rgbFormat = maxon::PixelFormats::RGB::U8();
const auto storageType = maxon::ImagePixelStorageClasses::Normal();

imgr.Init(optW, optH, storageType, rgbFormat) iferr_return;
bmp->Init(optW, optH);
bmp->GetImageRef(SAVEBIT::NONE, true, imgr);
doc->GetActiveBaseDraw()->GetViewportImage(imgr);

ShowBitmap(bmp);

Bitmap is just black, which leads me to conclusion that im using it the wrong way.
How to use this new function properly and save to bitmap?

Hello! How can i do the same in C++?

The point is to set specific data by DescID. In python i can simply do what is on screenshot.

But for C++ case isn't that simple.
What i've tried already:

• GetDataInstance();
  In this case i can only access Object Properties container, but not Coordinates.

• GetDescription();
  Also tried to use GetDescription(); and go through using GetNext();, but the problem is that BaseContaner is const, so i can't modify it.

How to properly access any container of object?
Thanks!

Hello! I'm looking for a way to launch my ToolData plugin with preset.
Example:

How can i do it? Should i create and register CommandData plugin in my ToolData plugin project? Or there is another way to do it?

Thanks!

@m_adam Now i see the problem. Thanks alot for helping!

@m_adam Yes. I just checked that. A select few items with shift+click, and unselect with ctrl+click. Everything works fine.

I want to provide you my code, but there is a messy structure like this

typedef std::tuple<DescID, Int32, BaseContainer> MainMapCellArrayCell;
typedef std::list<MainMapCellArrayCell> MainMapCellArray;
typedef std::list<std::pair<MainMapCellArray, BaseContainer>> MainMap;
typedef std::pair<MainMapCellArray, BaseContainer> MainMapCell;

And i'm not sure it will be efficient way to help. Can i send you whole project to email?
