About my most recent question related to SMinMax? I think it got lost in the discussion.

RE: Generator crashes and guidance
I've refactored my generator so it generates the BaseObjects more direct rather than through some proxy nodes, since I'm just thorw the BaseObject out there and not storing them in a intermediary, specifically a std::vector the renaming, random crashes, and Meakeditable crashes have gone away.
I still have an issue with rotation via mouse and clipping. Since my generator does create OPolygon, OCamera, Olights, Osplines, etc. according to the docs I need to implement GetDimension(). I've recently done that in my Poly and spline generation code like so:
for (int i = 0; i < pnts.size(); i++) { CacheVec pos = pnts[i]; Vector pnt(pos[0], pos[1], -pos[2]); pntsPtr[i] = pnt; _cacheBounds.AddPoint((Vector32)pnt); }
_cacheBounds being a private variable of the type SMinMax. In GetDimension I use it like so:
*mp = (Vector)_loader.GetCacheBounds().GetMp(); // Bounding box center *rad = (Vector)_loader.GetCacheBounds().GetRad(); //box size
The generator is still producing a situation where when I Alt+left click the camera moves about the pivot of scene rather than around the object I picked, and things clip randomly. When I make my generator editable I also still can't orbit about the objects. I wonder if I not setting up the PolygonObjects/SplineObjects properly.

RE: Generator crashes and guidance
I'm sorry, I kept the code sample brief and changed some stuff to protect my code.
while (node) { // add obj to virtual hierarchy if (!node->GetUp() // the parent is root node>InsertUnder(lumiCache); obj = _loader.GetNextObject(); }
This is closer to what the actual function looks like, the loader gets the next object form the caching format and does some processing to make it a BaseObject. Since I'm creating a number of BaseObject, I'm wondering about ownership, does C4D own these once their inserted and passed back via GetVirtualObjects(), or am I still responsible for them, because right now I'm just throwing them in there and not maintaining them. Behind the scenes my loader holds these cache objects in a std::vector for later run when it get dirty. Maybe something with that state is also causing issues?

RE: Generator crashes and guidance
I have a FILENAME in my res file for the generator that I reference similar to so:
Bool dirty = op->CheckCache(hh) || op->IsDirty(DIRTYFLAGS::DATA); // if the frame changed since last time the object should be dirty if (_frame != doc->GetTime().GetFrame(doc->GetFps())) dirty = true; // if user changed fps since the last time the object should be dirty, and we should recalculate our frame ranges if (_frame != doc->GetTime().GetFrame(doc->GetFps())) { dirty = true; _loader.SetFrameTimes(doc->GetFps()); } _frame = doc->GetTime().GetFrame(doc->GetFps()); if (!dirty) return op->GetCache(hh); else { // always pass c4d back a null, otherwise the system will keep polling this function and get real annoying lumiCache = BaseObject::Alloc(Onull); lumiCache->SetName(op->GetName()); maxon::String file = bc->GetFilename(CACHEFILE).GetString(); if (file.IsPopulated()) { _loader.GetCacheManager()->Load(file, doc); BaseObject* node = _loader.GetRoot() while (node) { node->InsertUnder(lumiCache); } lumiCache->Message(MSG_UPDATE); return lumiCache;
The objects it inserts could be cameras, lights, meshes, splines, etc.

Generator crashes and guidance
I have a relatively complicated generator. It's loads a caching format similar to Alembic and builds and internal hierarchy in GetVirtualObjects. I need a little bit of clarity, and info is strewn in a lot of different places, it's hard to piece together.
My generator doesn't get centered on when Alt left clicking with the mouse and moving and it blinks out of view and certain camera angles, I assume something is wrong maybe with my bounds for that?
My generator crashes C4D when Ctrl copied, and when placing it under something that is being instanced. I assume CopyTo and my lack of an implementation of it might be the culprit?
My generator crashes when renaming, something probably to do with CopyTo again maybe?
Thanks for the insights on this matter.

Prorender style viewport rendering
I'm in the process of adding a renderer to the viewport of C4D and I wanted some clarity on functions I should be looking into. I've gathered that I need to make a VideoPostData plugin, and I've used Execute pixel to blanket the viewport in red on hitting the render in viewport button. I also discovered that I could use
GetMenuResource(maxon::String("M_VIEW_WINDOW"))
to add items to the Viewport menu. I'd like to have the user be able to turn my renderer on and off similar to Prorender and draw interactively in the viewport. What documentation, functions, or examples should I be looking into to achieve this?

RE: Make plugins work in R13? how?
Maybe a combination of both. Maybe FBX 7.1 didn't support it back then, or maybe Maxon didn't implement it. I think it's probably that Maxon didn't implement it. I'm no longer using the R13 SDK personally. There are other options that are shaping that are far better than FBX, but they require a newer version.
As a solution for you I'd say export the pose morphs as obj, then import them into Blender and FBX export from there.
FBX also has a python API so maybe you could script an export without having the dive into the older R13 C++ API. -
RE: Make plugins work in R13? how?
Where are you exporting the morph targets to? its wholly possible your other package supports creating morph targets from obj files, or alembic. I can't recall if R13 supported Alembic or not. Sadly plugins are forward compatible not backwards. Sorry.

RE: Compling against Alembic
I'm getting one linker error. It's better than with the R19 SDK, I used to get a lot more. I'm using the R20 SDK against Cinema 4D R20 with Alembic 1.7.1.

Compling against Alembic
I'm making a tool that compiles against Alembic and I'm getting a Linker error. Normally I'd use the MSVC FORCE option and ignore the error since on the surface it rarely causes any major issues, but I'm really curious of late. Is there nay specific gotchas I need to be aware of in the C4D MSVC configurations to get get this error to go away?
On another note, is their C4D API specific ways to directly open and write Alembic archives?
