Maya Monday - nHair part2

[@TheIcemanModdeler]

Thank for the tutorial and awesome tip for the folicles.

[@caseycbenn]

Was there a way to brush/style the nHair? Or is this only possible in Xgen?

[@Alice444V]

wow thanks. That was straight to the point and helpful.

[@j3jenkins]

Great tips! Thanks Daryl. Here's a Python version of your MEL that isn't hardcoded and has checks to make sure people select the right number and types of objects. To use: First, select a rigid object Second, select the hair system Third, run the script Hope it helps! import maya.cmds as cmds def getShapes( xform, fullPath=1 ): if fullPath == 1: shapes = cmds.ls(xform,long=True) else: shapes = [xform] if ( "transform" == cmds.nodeType(xform) ): # If given node is not a transform, assume it is a shape # and pass it through if fullPath == 1: shapes = cmds.listRelatives( xform, fullPath=True, shapes=True ) else: shapes = cmds.listRelatives( xform, shapes=True ) return shapes #------------------------------------------------------------------------------ sel = cmds.ls(sl=1) # make sure 2 objects selected if len(sel) > 2 or len(sel) == 1: cmds.error('Please select two objects.') elif len(sel) == 0: cmds.error('No objects selected.') # make sure they are the right type if cmds.objectType(getShapes(sel[0])) != 'nRigid': cmds.error('Make sure first selected object is an nRigid object.') elif cmds.objectType(getShapes(sel[1])) != 'hairSystem': cmds.error('Make sure second selected object is a hairSystem.') # hook em up try: cmds.connectAttr(sel[0]+'.nucleusId', sel[1]+'.attachObjectId') print(sel[0]+' connected to '+sel[1]) except RuntimeError: cmds.warning('Nothing happened. '+sel[0]+' already connected to '+sel[1])

[@darylobert]

AWESOME!!! I will try to get it added to Bonus Tools for 2016.

[@j3jenkins]

daryl obert Sounds great Daryl! Let me know if you run into any issues or have suggestions regarding the script.

[@avtpro]

Hi Daryl, Question at 10:10 in the video. if I'm importing a bunch of curves, is there a way to make the pinlock for all the curves to "Base" at once? thanks.

[@lordrevan901]

+AVTPro Make Sure you have the follicle selected and not the curve print `ls -selection` ; $selection = `ls -sl`; for ($curve in $selection) { setAttr ($curve + ".pointLock") 1; }

[@avtpro]

+Mike Johnson Thanks I'll give it a go.

[@dj0kupas]

How to set multiple curves at the same time to hang on the base? 10:08. Its very tyering to do it one by one

[@luishernandez-zo3ul]

at the end of your video when you suggest not using the follicle in order to save dynamic time. The one curve you created you had to change point lock from both to base, it works but on the project i am currently working on I have 200+ curves and I have to switch each curve individually. Highlight selecting all the curves and switching from both to base only applies to the last selected. Any suggestions?

[@furiousmicro6777]

what settings must be kept so that the hair won't fall off but rather slightly wiggles need help pls

[@avtpro]

Hey Daryl, is there a fast script to connect joints from guide to be driven by nHair after a convert to poly? I'm using it to drive custom archive. It works but it's manual. I was interested in automating it.

[@mrteknas]

whats in the group you selected to make curves to guides?! i came from part 1 of your video i have a hair system.

[@CarlosSantos-qn8oc]

Hello, I have a question. I will animate my character. But nHair will have to be parentiado with a joint head to track your movement?

[@fakepivot]

Hey thank you very much.. these video are really helpfull

[@darylobert]

thx :-)

[@stefan.holst65]

Is there a reason why dynamics do count Maya units as meters when, I think, everything else is counting them as cm?

[@znbk5652]

Just really wondering... why are there hidden channels in maya nodes?? like for example this "nRigid1.nucleusId" or " hairSystem1.attachObjectId" unaccessible channels.. how could we find such channels if we can't find them in any node editos????

[@darylobert]

+ZHR NBK Its in the Documentation > Technical Documentation > Nodes > nBase It also show up in the Node Editor if you right click on the shape node and select show all attributes.

[@znbk5652]

+daryl obert no man I already tried to (show all attributes ) but it wasn't there

[@darylobert]

are you sure you are on the shape node? Its right under Message and above Output.

[@sabawind22]

Hi Daryl... what's the command to attached the hair to the geo for many hair curves? Hope you get this message. this is only for one...connectAttr nRigid1.nucleusId hairSystem1.attachObjectId;

[@legar83]

The collision quality of xgen primitives doesn't seems as robust as nhair even when using alembic mesh as collision mesh using xgen collision modifier. Any way to improve collisions when making xgen prims dynamic? thanks so much.

[@artspam]

Useful speed trick ! - Are there any drawbacks to using it? another speed trick when generating nhair caches: hide the hair for the cache generation process (if you didn't plan to monitor it anyways)

[@darylobert]

great tip!

[@mrteknas]

when i make the xgen hair, its not following the guides. and it is also not dynamic

[@WillSharkG14]

Is it not overkill to simulate every hair? Would it not be more efficient to simulate the guide hairs that are, say, 10% of the total hair count. Then interpolate the guide hairs with render hairs? 50,000 hairs for a full head of hair if not going to be enough, 500,000+ seems to be getting closer to a better result, probably a lot more through depending. Or maybe what you are detailing in the video is only part of an overall workflow. EDIT: oh, I've just realised this is part 2, so no doubt the answer is in part 1 :D

[@darylobert]

Hi TomCruisePope, You are 100% correct I would only run the simulation on the guides and let XGen handle all the instanced primitive splines. This is actually what I am doing the quick tip but with only a 100 or so guides and maybe 500 instances.

[@danielchurchill6688]

Hey daryl :) Who is this Duncan you keep referring to i've subcribed to your channel and am wondering if he has one too. p.s I really enjoy your videos keep it up

[@Aitor]

Duncan Brinsmead is the principal scientist at Autodesk. He created Maya Paint Effects, Maya Hair, Maya Toon and more recently nHair, nCloth and the Nucleus dynamics solver framework. Daryl, nice videos by the way!

[@HapZungLam]

thx Daryl

[@darylobert]

:-)

[@Snakebloke]

Yaay!

[@Snakebloke]

Awesome tips, thanks a lot Mr. Obert! :)

[@darylobert]

Snakebloke anytime

[@scottdaniel5803]

It is too bad that none of your videos have caption options. Not every Maya user are hearing you know?
