MRS: Give em a hand!
Current Sprint: MK Base
- First blockFrame rigBlock
- Time Context
- Continuing to iterate
If you’re currently using MRS you’ll wanna look at these until I get a chance to update the docs.
- NEW Block – HAND
- Context Setting
- Context setting now in a frame to hide them to clean up UI
Forceis a new option to say whether a block should redo a state when called. Most common use is when you have blocks a varying states in a heirarchy and just want everything at the same level without redoing states
- When in self state, force is always assumed. This just feels better
- Up to skeleton state, parent block state no longer matters.
- Foot tracks to the cast plane now (ground usually)
- Mirroring blocks should now work more consistently with loftList setup
- Utilities Tab | Mirrored most of the td section of the cgmToolbox here to make them easy to get to.
- Core attributes
loftReverseNormal| Because maya is consistently inconsistent with lofting. Between sessions. It’s nutty.
- New Menus/Options
Contextual>Prerig>Handles Lock/Unlock| Lock and unlock prerig handles when you need them to not move when you’re doing shaping stuff
Contextual> Prerig> Arrange Various options| Snap the prerig handles along multiple arrange options
Contextual>Vis| Easy way to toggle rotatePlanes and visMeasure on and off
Contextual>Queries>Visualize Hierarchy| fixed
Contextual>Queries>Reorder UD| [IN TESTING] During some build options the channel box user attrs get out of a sensible order. This is the first attempt at fixing that
Contextual>Rig>Prechecks| Connected precheck ability to check blocks for settings problems before building
Contextual>Template>Snap to Rp| Snap template handles to rp like we had prerig handles
Contextual>BlockFrame>Align To| Aligns a block to it’s block frame if one exists
Contextual>BlockFrame>Shape To| Shapes a block to it’s block frame if one exists
From last update
Fix the items from the last update before doing the final workshop package and a few new ones.
Stuff to fix:
- prerig layout stuff not working
- When we have same joint count as handle count, use the prerig handle positions
- Look at segment aiming. Saw a few flips
loftStart/End not setting up properly for mirroring block
- Reworked the mirror_create call in where settings are put in
Look at foot ik tracking
- Trying a point constraint group on the bank setup that doesn’t orient with the end handle
- Shaper aiming
- Add twist along segment
Pivot helper pivot handle placement. The bounding box method is not accurate
- Snaps to closest point on curve shape now
End handle on quad leg aiming weird by default.Fixed Add a way to lock the position/rotation of the prerig handles/template handles when you’re moving other stuff.
- Add the orient interp fix from segment to other modules
- Change states
Only skeleton/rig state should require parent blocks to be at the same state
Visualize Hierarchy not workingFixed
Add an attr sort to the rigBlock to make finding stuff easier in the channel box
- Added to ATTR and ui.
- Add mirror world space call
Add a forceNew toggle on the push states to make everything not have to rebuild unless you want hook up vis for that and measure
- New menu
- New menu
We need a new block. A helper block to more easily set up hands. So, let’s do it.
We want a way to more easily layout and setup a whole hand. I’ve been thinking about this a while but it’s best to do some doodling to work through things.
Googled some hands and start looking for simplifying the curves of definition for our block.
We’re going to be using some of the tech from our facial blocks to set up our points of definition. Here’s the rough plan:
Gonna start working through things by grabbing the define call from muzzle and work from there. First we need to to figure out what info we need from our user.
- definePose | Going to use this to specify scale space profile for he setup. To start wide and relaxed will be our options.
Got a first pass on placements. Look at things and see what we think.
Need to connect visibility of thumb parts to attributes hasThumbInner/Outer maybe The sub controls need different colors and to aim
So the way we’re doing this is as a frame for other blocks. So we need something to call this. First idea is ‘megaBlock’. This block type:
- Doesn’t go beyond define state (at least for now)
- It needs sub calls:
- Build other blocks
Got the initial finger creation and attachment working. Next is to:
- Properly size blocks
- Set block names
- Split the attach out to a new call
- Make attach work with template state/prerig
- Then thumb
Working directly with the blocks felt a bit slow. So instead I started playing with visualizing the hand here. Then I’ll add work on pushing that back to the finger blocks.
Overall this feels much faster and intuitive than directly going to blocks.
Further iteration with thumb
Initially we’re just going to do an outer/inner thumb. This is just easier and if you want another thumb you can just dup those blocks after the setup builds the sub blocks.
Need a way to shape the rigBlocks from the Hand block
First we need to map the data we want to use. Even though we’re only having one thumb for now, we’re going to wire it for the future.
- Handle drivers
- finger[i]Drivers | msgList
- thumbInner/Outer[i]Drivers | msgList
- finger[i]Curves | msgList
- thumbInner/OuterCurves | msgList
- finger[i]LoftSurfaces | msgList
- thumbInner/OuterlLoftSurfaces| msgList
Now that that’s stored. When we build our individual finger blocks we want to tag some data so we can get that track data so we can then update those blocks at will. Either all of them or just particular ones.
- Should be able to index from that
- Then get data
Scaling Loft Curves Properly
So we want to be able to use transform scale to size our loftCurves. It would be easier to just cast cvs at the target surface but this will be more consistent. Bounding box method doesn’t work when things start to rotate so we’ll go back to an older method and bring a call back from a long time ago to get the axis box size.
- Initially tried axis box but it doesn’t work well for flat curves
- Went to the oldest setup and brought back up to current libraries as
Working pretty well. On to the rest of the fingers tomorrow.
With some more iteration got the fingers all setup and the ui elements added to work with things.
Review with Bokser
Connect vis of thumb groups to numThumb Creation loft curve size – try a factor of the length from start to end Flip the limb end aim to be z- so that we can snap hands to them easier Add a designator for FRAME on ui
- Play with aim vector for hand finger curves
Circling back to this…
- Update mDrake
- Update Horse
Need to revisit all the docs to cover the new define state stuff as well as hit loftList
- HAND – First pass
- Tools docs
Had an issue where I rolled up update into a branch and broke some stuff for a user. I need to add better MRS unit testing and so that’s going on the to do list.
Benn is using MRS for a pipeline and writing a call to batch process templated rigs and needed a hand with finding calls.
Needs to get master block
Rig state call command
RIGBLOCKS.contextual_rigBlock_method_call(mBlock, 'below', 'atUtils', 'changeState','rig',forceNew=False)
Check if rig Built
ml_context = BLOCKGEN.get_rigBlock_heirarchy_context(mBlock,'below',True,False) ml_fails =  for mSubBlock in ml_context: _state = mSubBlock.getState(False) if _state != 4: ml_fails.append(mSubBlock) if ml_fails: pprint.pprint(ml_fails) raise ValueError,"We have some failures..."
- Mirror Verify
- Gather Space Drivers
- isHistorically interesting
- Connect rig
mPuppet = mBlock.moduleTarget#...when mBlock is your masterBlock mPuppet.atUtils('mirror_verify') mPuppet.atUtils('collect_worldSpaceObjects') mPuppet.atUtils('qss_verify',puppetSet=1,bakeSet=1,deleteSet=1,exportSet=1) mPuppet.atUtils('proxyMesh_verify') mPuppet.atUtils('rigNodes_setAttr','ihi',0) mPuppet.atUtils('rig_connectAll')
ml_blocks = r9Meta.getMetaNodes(mTypes = 'cgmRigBlock',nTypes=['transform','network']) for mBlock in ml_blocks: mBlock.delete()
MRS Animate – not working as expected
- Wasn’t up to date
- Clav shapes different size
- Cast direction
- Settings shape size mismatch on Benn’s file
