[Bf-animsys] Grease pencil and Storyboarding

[mendiobox]

Hi Joshua,

Thank you for the quick response!

I’m glad that you’re working on the bugs I found. 
I have a fresh one today: On gooseberry branch (2.73 branch is all ok). When your are editing GP strokes there is no more hint about what are selected (yellow color on points). They’re all black. it will be great if you could check this ASAP. 

Some notes: 

DOF viewport behaviour: You’re right, It will be better to contact Antony (but right now I think he is on his holidays)

FILLS: I’ll wait your research/proposal to improve it :)

SMOOTHER BRUSHES/FREESTYLE: Cool! I'm really excited for this stuff, can't wait!

LAYER GROUPS: I’ll make some UI mockups with ideas and I'll let you know. My first guess, since we don’t have something like this in the Blender UI,  is to use something similar to the outliner with + and – sign to expand or contract layers group. What do you think?

ERASER (F KEY): As you said, use it only on GP edit mode was my intention.

PAINT CURSOR: What I’m looking for is a less distractive way to paint strokes on GP. The brush icon is ok to make some simple notes with the GP but when you’re working on complex drawings is better for artists to have a more precise and less distractive icon (like a transparent circle with the same size as the thickness selected for the strokes). Maybe this could be an option on preference like “use precise cursor” or something.

I'm planning to work a lot this week with the GP tool trying to do an entire storyboard scene from Cosmos Laundromat in Blender GP, so I'll let you know anything else that I could find.

Keep the good work coming!

Regards
Matias

Hi Matias,


Thanks for the feedback :)


Re - Bugs:

1) Yep, I've noticed it too. I thought it was just me, but apparently not :) 


2) Not intentional. Fixed in master now.



Re - Primary Features:

1) For viewport effects, it would be better/faster to contact Antony (psy-fi).


2) Better fills (without the artifacts we're getting now - like incorrect fills in concave areas, and the bug above) are something I will look into. The current GL_POLYGON based technique was intended as a quick first pass so that we at least had some way of doing this, which works for a decent number of scenarios.


3) These will be looked into :)


4) I'm looking for ideas about how exactly artists would like/expect this to work, and how that would fit into their workflows :)



Re proposed improvements:

1) There are some issues doing this. Perhaps the greatest one is that we can't just always use the FKEY, as it would end up blocking normal tools from working. This is especially true when not in Stroke Editing Mode (where Grease Pencil is just "on top" of everything else). Then again, if it's not going to be too much of a hassle to only be able to do this in stroke edit mode, then it should be simple to add it.


2) I'll have a look. I suspect that this won't be that useful, as the maximum size is limited by the fact that OpenGL on windows limits the maximum width of strokes drawn using the opengl primitives



Regards,
Joshua

  Hi Joshua Leung (and everyone here)

  I'm Matias Mendiola, the storyboard artist in Gooseberry project.

  First let me tell you that you’re doing a really great job on Grease pencil. Congratulations!
  The idea is to use Grease pencil as the main tool for storyboarding and animatic process for future Gooseberry storyboard work, so Ton told me to get on contact via this mailing list in order to give you my feedback, request, proposal, etc.

  Just to start, some notes about Grease pencil:

  Bugs:

  1. I have a weird bug using fills (seems related to NVIDIA card) on one of my computers. I created a bug report here https://developer.blender.org/T43149

  2. I notice a diferent behaviour when deleting: DEL key don't work the same way as X key to delete when editing strokes. Is this by design?


  The principal features that I'd love to have in GP soon to test for Gooseberry Storyboard (some of them are on your blog already):

  1.  DOF on Viewport OpenGL. (Now it works on Gooseberry branch but on all strokes the same no matter what distance they are to focus point)

  2. Fills only inside shapes.

  3. Brush types or Freestyle integration for more artistic and smoother lines

  4. Layers group to make easier the work on different characters/backgrounds


  Proposals to improve GP:

  1. Use F key to change eraser size (as on texture paint mode)

  2. Posibility to change the paint cursor icon to brush size (as on texture paint mode)


  Let me know anything you need for me and please be aware that I’m living on the other side of the world (Argentina), so delayed responses could happen. :)

  Best
  Matias
