Short description of error
Intrpolation betwenn keyframe is constant even when Bezier, Linear is chosen
Exact steps for others to reproduce the error

This resemble slightly a bug I reported a week ago, but with slightly different appearances. (I think it was T60621.. as you broke down the task, the keyframe issue for the armature).

Please find also a video of my Blender screen with the problem.

I tried create a stick man walk cycle. As you can see from the video, the interpolatin is constant even when Bezier or linear is selcted.

When I move to the Graph Editor the keyframes don't appears. Contrary to the above mentioned bug where keyframes appears only on the Graph editor and not the Dope sheet.

I keep these two together, as it seems to me somehow related, I didn't want to create another bug and create a confusion.

This is not how Grease Pencil works. It cannot interpolate between frames unless you go to Edit Mode and select Interpolate from the Edit Mode header, in which case it generates new keyframes in between. GP is designed as a frame by frame 2D animation tool, akin to TV Paint or Toon Boom.

A drawing cannot be interpolated using an F-Curve. So this is not a bug.

I don't mean to be harsh, but I would recommend you learn the basics of how Grease Pencil works before posting these bug reports. :)

Cheers.

Hi,

Thanks for the detailes. I'm learning.

First you can be harsh, if you are right it is up for me to face it.

I try to learn how it works in particular from your tutorials, ex: Antonio's Grease Pencil Basics, which I tried to repeat here.

I couldn't repeat it steps, I looked for additional ifnormation and actually I onl reported on arbitrary issues.

As you might note, some of my previous bugs were also confirm to be right. I made some animations more than 10 minutes in total, I confronted some tough situations, I never reported a bug before.

I did it as I encountered arbitrary situations... ex: I never came across when keys appear on Dope sheet and not Graph Editor and vice verce ( I had both issues).

Also, the concept of points was not in 2.79 and the Grease Pencil isn't the same.

I do reserch before reporting a bug... exactly because it can expose my limits and nobody like to fool, I'm not an exception. I do try to search before, I also post on forums, CG Cookie etc'.

In 2.79 when a function wasn't available, it was greyed, i.e. disabled. it confuses when one can execute something that isn't meant to work.

You can see for exemple in the Video attached herein, that I cannot repeat what you suggested, nor what is seen in Antonio's tutorial.

Where Antonio's created keyframes both in the sculp and the Edit mode, I could create them only on the Sculp Mode.

In case it is helpful.

For the sake of clarity, I have no issue if you think I'm not educted enough to report bugs, you are probably right. I can defenitly avoid any in the future.

I tried to provide my feedback, to the best of my knowledge. If this isn't good enough for you, just say. I's still think high of you. Be harsh, all is good, really.

Cheers,

DB
