Released a build of Morpheus 2 this week and immediately ran into some issues with the marking menu and hot keys. I’d been using zooToolbox’s setup for years for hot keys but it didn’t work with 2016 so I dug in.

Maya 2016 has a pretty neat new editor but it’s still probably more steps than most of our users could reliably follow so wanted to get the button push setup back.

There a few things to remember when working with hot keys and in this order…

  1. runTimeCommand– This is the code that gets run. It can be python or mel
  2. nameCommand — This is required for a hot key to be setup properly
  3. hotkeySet — This is something new with 2016 and needs to be set to a new set to be able to add a new hot key because the default set is unchangable
  4. savePrefs — after setting up your hotkey, you must save the prefs or they newly created hotkeys go away (not sure if this is new to 2016 or not)

Lessons learned:

  • hotkeySets — were added in 2016. Any hotkey work you do post 2016 needs to account for them. I ended up having my stuff use the existing set if it wasn’t the default and create a new one if the default is the current one
  • hotkey -shiftModifier flag — this was added in 2016
  • Pushing dicts into mc/cmds calls — In general, something like mc.command(**_d) works with _d being your dict. However on mc.hotkey I found that the keyShortcut flag needed to be in the dict and at the start of the call to work: mc.hotkey(_k, **_d).

I ended up writing a handler and gui to set stuff up. I’ll swing back and talk about it another time if there’s interest.

Back to Morpheus…

As I’ve been closing in on finishing Morpheus 2 I found myself in need of a distributable skin data system to be able to apply skinning information to Morphy meshes after they’d been customized and no longer matched up with the base mesh. Not being able to find a good way of doing it in natively to Maya and not finding any open source options, writing our own was the only way forward.

Thanks to Alex Widener and Chad Vernon for some tech help along the way.

Before delving in here, here’s some lessons learned along the way.

  • mc.setAttr — found this to be a unreliable method of setting weights via the ‘head_geo_skinNode.weightList[0].weights[0]’ call convention. Just didn’t seem to set properly via any call but the api.
  • mc.skinPercent — call is hopelessly slow and should never be used for intensive work. A query loop went from 78 seconds to run to 1.3 simply using an api weights data call even with having to re-parse the weights data to a usable format.
  • weights — speaking of, this was an obtuse concept to me. This is regards to the doubleArray list used with  an MFnSkinCluster. In short the easist way to get to a spot in this data set is as follows:
    • weights.set(value, vertIdx*numInfluences+jointIdx)
    • weights — doubleArray list instance
    • value is the given value you want
    • vertex index * the number of incluences + the joint index = the index in the array
  • Normalizing skin data — You usually want your skin values to add up to 1.0, so here’s a chunk to help

The initial list or requirements for the functions were as follows:

  • Readable data format — decided on configobj having used it with some red9 stuff and finding it easy to use.
  • Export/import data sets
  • Work completely from the data file for reference (no source skin necessary)
  • Work with different vertex counts if similar shape
  • Used indexed data sets for easy remapping of influences

With that being said. Here’s the demo file link and you’ll need the latest cgm package to follow along. Open up a python tab in the script editor and try these things one line at a time.

This is a first pass on this thing till Morphy 2 is done.

Cheers!

So,  a chat with a good buddy (Scott Englert) on the topic brought up one more item I’d neglected to rule out in the previous bit of research.

Flush prefs.

Dur…

So I did and the issue vanished, which led me to delve into what script or preference was causing issues. Did this by re-adding files and scripts to figure out what it was. As it happens it wasn’t a specific file but an import that did it. In the end, I found 2 issues at play – one of which is solved but broke my unit tests so I’m waiting to for Red9 to figure out how to resolve. In this case it was registering ‘transform’ as a nodeType in r9Meta stuff in one of my __init__ files.

Hopefully finding this will make the red9 stuff which we love all the better once it’s resolved and keep others from bounding into the time sucking vortex that resulted.

Lesson learned – if something is acting weird, clear prefs and see if it fixes it and if it does, start adding stuff back till you find the culprit.

While doing some optimization on Morpheus 2 and incorporating some of Red9‘s latest stuff I noticed an odd bottleneck in the code.  So I decided to dig in to it.

For those short of time, the short of it:

  • Maya’s duplicate command get’s slower based on scene complexity – regardless of manually calling or doing it through the interface
  • Maya’s duplicate command (and perhaps others) get slower based on how long you’ve been doing stuff in maya

I noticed that a relatively simple step in one of my joint chain functions was oddly slow and delved into it. In a empty or lite scene it was pretty instantaneous but in a regular scene got really slow. Dug in and came to just being duplicate being slow. That was my theory at least , so I wrote series of tests to verify. The first of those being a test that given a number of times to iterate and a number of children joints, the test will 1) create a joint chain of y joints and 2) duplicate that root joint iterating on the provided number. 

The results showed a pretty linear line of increasing speed as the scene added more objects. The more objects, the longer things got. Interesting but not enough to go on.

The second series of tests I wrote my own simple joint duplicate function using mc.joint and matching positioning, rotateOrder etc. I also checked some other items to eliminate those as possible hindrances or see if they affected speeds:

  • Undo – No difference whether it is on or off
  • History – No history on joints
  • Connections — Only connection on any tested joints in inverseScale
  • Flags — Tried all combinations on the duplicate command I could think of to no avail
My rewrite is always the same speed regardless of complexity, mc. duplicate get’s progressively slower as it goes on. Here are some results:

Breakpoint is the iteration at which my rewrite is faster than mc.duplicate for that run. Method 1 is mc.duplicate and Method 2 is my own.

How about some code you can play with yourself with a simple locator duplication?

Here are some results of this standalone for me at least:

Note – the 2015 run was a fresh open of the software and my experience doing this testing would see that getting slower.

If you run the test you’ll see for yourself the slow down. Now, what do we do with this?Working through this I created my own duplicator for curves, joints and locators. For now, I’m only going to use the joint one for Morpheus building until I can do some more testing and maybe get a better handle on it but it’s certainly an oddity.

Odder yet is the longer you do stuff in Maya, duplicate gets slower still. This I tested after noticing that after being away a bit that Windows had rebooted and suddenly duplicate was posting much better results. After a while, that slowed down. So I rebooted myself and yup, it’s faster after a reboot.  I have no idea on this one other than maybe a memory leak or..I dunno, I’m a hack at this stuff and that’s the best I got:)

If you’re interested, let me know what you find – different conclusions?

For now, Bokser told me I have to move on:)

Introduction
We have partnered with Rigging Dojo on creating special project “Rigging for Morpheus” that aims to cover learning how to integrate the red9 tools, how to work with an existing open source library and with set standards so that students can build tools, expand on/improve and contribute to the opensource CGMonks Took kit as well as the Morpheus rig project.

This isn’t a class to learn to use Morpheus – that will be handled via some vids at release. This is for those td’s who wanna join in in making as great a shared tool set as possible.

Class is kicking off next month. Registration can be found here:
http://www.riggingdojo.com/home/registration/

All registrations must be in by 31 December, 2013

Studio Portion
The specifics of what that studio session will cover will be subject to what the ‘students’ want to do. If everyone wants to work on customization stuff, then we’ll work on that together, if one student has a great idea for a tool and just needs help learning how to build that and integrate it to an existing ‘pipeline’, we’d support that student on that and maybe other folks on something else.

Potential Paths

  1. Customization — Work through building guts and tech for the finalizing the Morpheus 2 customization setup. This would be tackling such exciting items as – blendshape libraries, hair, prop clothing implementation. Definitely a beard. Morpheus needs a beard.
  2. New module — Build a new module for the system like a wing, long neck head, quad leg or perhaps some more mechanical setups. This would entail designing and implementing template objects and learning to write and push that through to a final rig item that ties in to the rest of the modular rigger.
  3. Facial system — Work through learning the new methods and tools of the Morpheus 2 facial rig. Polishing, adding features and learning how to build on it.
  4. New/Existing Tool Pipeline — Learn the bits of designing and writing a new tool for maya – from gui, designing for user friendliness, breaking down the tool to build-able bits, debugging and more. If students have tool designs we can start from scratch or we can grab from the ever growing pile of internal ideas from CG Monks.

Cost
Class (8 week intensive apprenticeship)
$1226 – base cost
There are discounts available for Morpheus 2 backers. See the development forum post for  more info.

  • Try to draw the hair in its neutral position (not in movement).
  • If your hair style is somewhat complexe please provide some general notes. You can scribble those on your template (dont overlap the drawing too much).
  • The styles will be split into 3 categories: Short (above shoulders), Medium (shoulder level) & Long (below shoulders) so please try your best to be clear on the length.
  • You don’t have to submit sparkling clean designs. Clear sketches are more than welcome.
  • No submission limits.

Template files

Requirements

  • Submit in PNG or JPEG.
  • Naming convention: YourName_HairCustomize_v00.ext (the versioning is not for WIP numbers but for your designs).

So saw some questions on these enigmas around and wanted to attempt to shed some light on them.

optionVars are maya devices for saving information between maya sessions, from say one tool session to another or any other wide variety of things. By default you use them like something like this:

If you decided you wanted to play with optionVars. They’re awesome but can be a bugger to get working the way you want them. We use them to save settings between gui sessions and even to send info to some stand alone functions.

If you want to add to a string one you have to remember it’s a string one and use a different flag than a int or float one. It got confusing to us, so we decided to go a different route.

We wrote a class wrapper for dealing with them that made it easier for us to get a handle on so that we call them at the top of any gui with something like:

That initializes the option var to an instance that can be appended, rebuilt, culled purged, cleared, call, converted or whatever in any of our tools.

The defaultValue flag sets the value only if the optionVar doesn’t exist. We did that so that if a specific tool is reset and has it’s flags wiped. It builds again with the default ‘factory’ settings. It also converts on the fly so if you pass a string to a non string optionVar, it converts it to a string, and so on.

Settings are called and set via commands like:

We also flag all of our optionVar’s with a ‘cgmVar’ so that we can easily do a full wipe of our variables when needed for testing.

You’re welcome to give it a try if you like or take part of it it works for you and run with it or join us and help make it better. It’s in the cgmTool box from cgMonks – cgm/lib/classes/OptionVarFactory

Have a great weekend!
