As I mentioned I currently use other programs for FBF animation in my personal work, if anyone is wondering what they are here's a list...
Adobe Animate. Since the end of last year, I started using Adobe Animate (formerly Flash,) to create FBF image sequences to use in my Moho projects. Animate's FBF navigation, timeline, and editing tools are still clunky but its freehand vector drawing in the program still works well and IMO more predictably than Moho's Freehand. Animate's equivalent tool to Moho 13.5.5's Freehand is the Paint Brush tool which draws an open curve with bezier points. Paint Brush draws clean lines similar to what we get in Moho but without some of the odd end-point issues or unwanted redraws. This allows me to reliably create FBF items that match my other drawings created inside Moho. (By comparison, I found it harder to draw FBF in Toon Boom to exactly match my Moho drawings.)
One thing I dislike about
editing vector drawings in Animate is that there is no equivalent to Moho's Magnet tool, which I use ALL the time in Moho.
In recent years, Animate has been getting puppet rigging improvements, but it's still pretty basic and I haven't seen anything there to make me want to switch from Moho for that. (IMO, Moho is still the tops for puppet animation!)
Toonsquid. I've been dabbling with a fairly new FBF app for iPad called Toonsquid. Like all iPad animation programs, it's not full-featured, but It's easy to use (UI is similar to Procreate,) has good drawing tools, and being on iPad it's as mobile as you can get. TBH, I don't use ToonSquid for drawing FBF for Moho, but I'm mentioning it because it's cheap and works well if you don't mind the hassle of working between multiple platforms.
Krita is an awesome drawing program with FBF tools, and it's still completely free. I like Krita for drawing but my biggest complaint about its FBF workflow is that it can't display an audio waveform, which I feel is necessary for accurate audio synching. If developers would add this one feature I might use Krita's FBF tools more.
TVPaint. If you want a natural media look in your FBF animations, it's hard to beat TVPaint. Sadly, I don't use this program enough. I still keep my TVP dongle attached to my home desktop but it's been a long time since I last launched it.
Here are some programs I want to spend more time with when I'm able to...
Blender. Actually, I've been using Blender regularly this past year in personal projects and at my workplace, but mainly for realistic 3D and VFX work, not 2D cartoons. I haven't touched Grease Pencil yet, but I'm looking forward to it. At my workplace we had an introductory class on Grease Pencil basics...and it was one of the few Blender classes I missed, darn it!
Having this capability in a 3D program invites intriguing possibilities, but I don't see Grease Pencil replacing dedicated FBF programs for 'traditional' 2D animation. But I do occasionally use FBF image sequences inside 3D projects, and I can totally see myself using Grease Pencil for that.
BTW, even though Blender is free to use, I've been donating to the Blender Foundation this year because I'm finding myself relying more and more on Blender in my personal and professional work lately. It's that good!
OpenToonz has always intrigued me but I haven't spent much time with it. There's also a variant called OpenToonz Morevna Edition that has a different UI. Both versions are free (but will accept donations.) I'd probably use OpenToonz if I didn't have Animate as an option for personal and work use, and we don't have OpenToonz at my workplace. I keep seeing stunning FBF work done with it though.
To sum up my list:
Krita, OpenToonz, and Blender/Grease Pencil are all capable tools and free.
Animate works great and the look of the strokes matches well with Moho's vector drawing. It isn't free but it's relatively 'cheap' if you use several tools in the Adobe CC suite every day (which I do.) I like
TVPaint but it's not 'cheap' and TBH, I'm not doing much work with it these days.
Toonsquid is a fun, cheap option if you have an iPad.
And of course, Victor had mentioned in another thread that
Moho may see FBF improvements in the near future. I'm very excited about this because most of my FBF work created in other programs typically winds up in a Moho Image Sequence layer anyway.
The above is my personal opinion of course. If I left out a notable FBF program, it's because I'm not using it, am not personally interested in it, or am unaware of it.
I'm curious to hear what other Moho users are using for FBF animation.
P.S., I almost forgot: I use Clip Studio Paint too, but only for making comics. I don't use its FBF tools so can't comment on them.
Also, during
Boss Baby: Back In Business, I used Photoshop's FBF tools to create FBF elements in my Moho projects. Photoshop's FBF worked well for what I needed at the time but it's pretty basic.
