    Congrats on finishing that first project Blond.

    On my end I am starting to dabble into Blender rigging and posing in the hope of soon getting into animation (I will probably maintain a thread of noob questions on that topic on BA). Now that you took the process from start to finish, could you maybe list an exhaustive (but not redundant) list of learning materials/videos that made it possible for you to get there ? This could be helpful for a lot of people starting out.

    You might be interested in this for learning to rig in Blender http://www.blender3d.org/e-shop/product_info_n.php?products_id=146

    I bought it a couple of years ago and watched through it, there was lots of good stuff in there.

    I learned a lot from Lee Salvemini's excellent rigging series on Blender Guru:

    http://www.blenderguru.com/tutorials/introduction-to-rigging/

    Probably out of date by now in a lot of areas - but very well set out with the basics explained.

    Anyone here use Blender for sculpting? Or in particular did sculpting in both Zbrush and Blender?

    I have always been sculpting in Zbrush, but thought I'd try it out in Blender, seeing as I use it for practically everything else. One thing bugs me A LOT though. My eyes can't seem to get the right feedback for any sculpting I do on the model. So basically I can't 'feel' the depth, so I'll make a change, and if I rotate the model, the changes are extreme and ridiculous.

    I tried playing with the lens angle, various matcaps, but it just seems like it doesn't make much difference.

    Has anyone had the same issue? And in that case, know of a solution? Maybe I just underestimate the complexity of that feedback, and have been taking it for granted in Zbrush.

    Not sure if it's still the case as I've changed mine a little but by default blender has(had?) two standard sculpt brushes "Brush" and "SculptDraw". I used to accidentally toggle between them with the hotkey but they had different setting so would often do something I wasn't expecting like you described, making huge changes to the surface form.

    If it's still a problem you can get rid of brush by shift selecting it and shift clicking the X below the picture of it then save and restart blender. Can even do that then file>save startup file and it will be gone in the default scene every time you start blender

    @derphouse - Do you have the ambient occlusion option on (in the "n-panel" around where the matcap option is)? I usually have to fiddle with the settings a bit, but it makes it a lot easier to see the bumps and things while sculpting.

    Derphouse : this is very interesting ... because for me it is actually the opposite. As in, I find it near impossible to get a good feel for the volume and surface qualities of a model in Zbrush, whereas the Blender viewport (and any regular 3D program for that matter) provide me with very accurate visual information.

    That being said, the default lighting in the Blender viewport is quite awful, so you might want to play with that first and foremost. One thing that helps a lot too is to set a shortcut for "Center View to Cursor". This allows you to make the camera rotate precisely around the point where the 3D cursor is located, which in turn greatly improves depth perception. As shown here :

    Hey pior, if you're looking to get into Blender's rigging and animation I highly recommend checking out the following two tutorial series. They do a great job of covering the fundamentals in a clear and systematic way and then they build on top of that. I got both of them and it really helped me to improve my skills.

    Thanks a ton for the links Mongrelman, Gmanx and Lamoot ! I really like what I see in the Blenderguru one, especially the simplicity of creating custom bone shape controllers as demonstrated at the end of part3, very cool stuff. I definitely need to watch all these.

    So far I have been going through this introduction to Rigify, and that too was surprisingly simple.

    [ame]


    It's pretty great to see how well this rig behaves, even when driving a model with mere automatic weights :

    EZwdAR2.jpg

    Only downside is that this control rig doesn't seem to be able to seamlessly transition between IK and FK without killing the pose of the limb being worked on. Or maybe I am just missing something ...

    Regardless, can't wait to learn more ! And another question in passing : is there a reliable Onion Skin feature (or add-on) available somewhere ?

    Yeah. I solved it way back when I was working in Blender for sculpting by messing around with the "solid OpenGL lights" under the tab in the preferences panel. There was a suggestion on how to do it from someone in this thread or another Blender thread on Polycount. Problem is I can't for the life of me find the post even though I've looked. It was night and day though, and at the time I thought it should've been the default way of setting up the lighting. You might be able to get something similar by messing around with the lights.

    Edit: Found it by using Google instead of default Polycount search.

    http://www.polycount.com/forum/showpost.php?p=1588727&postcount=76

    is what I originally did.

    http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/3D_interaction/QuickPrefs is an addon that has multiple presets to fix this.

    http://www.polycount.com/forum/showthread.php?t=137986

    is another approach.

    Hey Pior, if you bring up the n panel (right hand side in the 3d view) and go down to rig main properties you can snap IK to FK pose or FK to IK pose then keyframe the bones of the inactive mode so when you switch the pose is identical.

    Rigify rig is really nice but because its so complicated it's hard to retroactively tweak and it also uses more bones that the game might need. If I use rigify I turn off deform on all the DEF bones and turn it on for all the ORG bones in the last layer. I think you can do it by selecting all the ORG or DEF bones in edit mode, finding the deform button in the bone properties, toggling it on or off then right clicking it and doing "copy to selected".

    @Dashiva hey thanks a lot! Changing the lighting actually made a lot of difference. I'm playing a bit with the matcaps as well. So far, no matcap and one light directly from above works pretty well.

    @pior I see what you meant about the default lighting now :D

    EDIT:

    @MmAaXx thanks! Yeah I agree I'm liking the control of lighting much more. Tbh, I love using Zbrush, but just like the integration of Mudbox into Maya, I imagine it won't be many years before Blender is at a high level with sculpting (Just looking at the increase in viewport performance now). And that's really my only problem with Zbrush; It has TONS of great sculpting tools, but I really only end up using about 5% of them, which means if I could quickly be switching between tasks in one app like blender, I'd be a happy man! I never really got into using ZModeler, so I can't really say much about that tool, but I haven't heard much about its use since release?

    Frankie, thanks, I got it now ! I was aware of these context-sensitive FK/IK switch buttons ... but it turns out that it was their labelling that was confusing me, and you led me on the right path.

    So basically, when currently working in IK and wishing to switch to FK (IK to FK), one has to click the "Snap FK to IK" button. It actually makes sense now that I think of it, I suppose I was just reading it too fast :D And there doesn't seem to be a need to even create a keyframe for that to work, so, it's all good ! Very solid stuff. My only gripe with the system is the way the foot and hand IK and FK controllers are of exactly the same shape, which makes selecting them awkward. I wish there were grouped and could be intuitively selected without having to think much about it. But that's a minor issue.

    No problem!

    Other animation tips I have are;
    -motion paths are great, https://dl.dropboxusercontent.com/u/1693140/game/motionpath.gif
    -alt+scroll wheel for changing frames
    -set up a custom hotkey for shift+alt+scroll wheel to skip to next keyframe
    -set up a custom hotkey to delete keyframe of selected object only in the 3d view (this was hard to do for some reason), its "anim.keyframe_delete" in 3d view > pose
    -you can delete the custom shapes and blender keeps the mesh data, get them back with "bpy.context.scene.objects.link(bpy.data.objects)" where WGT-shoulder.L is whatever you want to recover (or make a new scene and link all the custom objects there then delete from main scene)
    -latest version of blender makes you load the NLA editor to delete actions as it puts them in there to stop them getting accidentally deleted when they have no users.
    -paste mirror keyframe in 3d view is great but also now works in the action editor so you can mirror whole sections of animation, you need to select the objects in the object summary on the left for it to work though

    Thanks for the pointers !
    -set up a custom hotkey to delete keyframe of selected object only in the 3d view (this was hard to do for some reason), its "anim.keyframe_delete" in 3d view > pose

    This is precisely what I am having trouble with. If I use this command I am getting a "No active keying set" error ; and in general I am having trouble removing a specific keyframe from a specific bone. More precisely :

    Let's say I have a character with a large number of keyframes already, on 1-6-12-18-24. But then I am not satisfied with the keyframe for the wrist on frame 6. What is the process for quickly deleting this keyframe from the wrist bone (location and rotation), without affecting the other keyframes established at frame 6 for other objects? (all that without having to fiddle with the dope sheet or the graph editor, because having to select the bone I want to affect in these panels is redundant as I already have it selected in the 3D view). This is kind of driving me crazy :D

    [edit] Ha, nevermind ! Instead of recreating the shortcut I simply edited it, and it works fine now. Also stumbled on your original BA post on the subject :) It's so much better that way !!

    I wish I could rig, at least with basic bones to pose my characters for the presentation in my portfolio. But the process always stops at weight painting. That's just, so hard and frustrating...

    After automatic weights, you could give the mesh a corrective smooth modifier on top of the armature modifier. Mind though, this method is only for use within Blender, it wouldn't work with deformations in game engines and such.

    Am I the only one which is kind of disappointed there aren't more Animation or motion Artists within the Blender community?

    I mean, I've been lurking on the Blender Artists forum and been seeing their galleries for a couple of months. I even know the big names of the artists using them.

    However, of all the best and interesting stuff I see, it's always static renders (they're beautiful)...

    I'm still waiting for they day I'll see more convincing animations from the Blender community (I'm trying to do my part here but it looks like a harsh road).

    The only goond ones I've were the Blender short films one.


    If anyone of you even been to 11secondclub, you'll see most of the entries are done with or Maya (and sometimes Max)..

    Never with Blender. That must also be caused by the few number of (good) rigs available...

    - Warp mode for sculpt (allows to do tiling easily)
    - OpenSubdiv
    - the absolute grid snapping
    - automatic node offset
    - the edge offset (without add-on)
    - Individual origins transformation for UV editor
    - etc.

    Also widget project begin to be ready for early tests : http://code.blender.org/2015/09/the-custom-manipulator-project-widget-project/

    Is there any exemple file available showcasing the increased viewport performance ? I think I am seing a little bit of a boost on heavy models, but nothing drastic. I am not quite sure what to look for - for instance, there is no mention of which viewport mode is supposed to be affected, and so on.

    Personally, I'm more excited to have a real snap to grid available in addition to the snap to increment. That and flatten ngons seem pretty nice and useful. Perhaps I will make use of the tiling thingy someday but right now my CPU is too weak to sculpt a typical tiling plane at a reasonable resolution, so I will have to stick with Zbrush or Krita.

    I have mixed feelings about the viewport performance.

    They seem to have focused on improving the subsurf modifier, which is useful,
    but I see no improvement in raw meshes and Blender is ages behind Modo in this respect.

    It's a very fragmentary solution, hope there's more to come in terms of the viewport.

    So yes, that's the early steps, one of the main task of 2.8 project is to update viewprt (shaders, PBR, perf, widget and stuff).

    If I remember correctly, there was some improvements on Multires (for people using OpenGL 3.2 capable GPUs) performance as well, but I'm not sure if these changes are already in master.

    And what do you guys mean by new skin modifier? I didn't see it anywhere D:. Skin modifier is one of the things I really wish where improved in Blender (it behaves a little too unpredictably). Don't give me false hopes D:

    And I totally agree with Yadoob, if you guys want to support Blender, donate some money (even 5€ helps a ton) to Blender dev fund or BlenderCloud (beware that this is more focused on the production of their short movies, so first see if what they're planning to do / develop during the production of the movie would be useful for your pipeline).

    Also just as a FYI : another way to support Blender financially (as well as Polycount, Marmoset, Xnormal and Handplane too !) is through Steam Workshop revenue sharing. In short : a fraction of what Valve earns on item sales can be redirected to approved third parties, if the item creator so choses.

    Regarding viewport performance : I will try to test it furhter, but I am a little puzzled that this video shows an example under Blender Render viewport, which is noticeably slower than Cycles Viewport (why it is the case I have no idea, but there is a definite difference). Can't wait to dig into this a little further.

    Actually I forgot about the thing where you have to start with a base mesh of exactly 1k-4k polygons that are evenly spaced to get good perf with multires on my machine. I also didn't know about the trick where you can apply base on the multires of a mesh, duplicate it, subdivide it one last time to get that mesh resolution, apply the multires modifier on that, sculpt it until it looks good, go over to the other mesh, delete all subdivisions above zero, subdivide it until it has the same number of points, and reshape the multiresolution modifier. It's still easier to get the performance out of Zbrush but this seems like it could work for my purposes, and being able to use Blender's procedural noises as brush alphas is really nice.
