I knew all the programs You mentioned, I'm going to talk about them a lines more down, but first I thought about using another programs as you said for example to create the assets for paperless or cut-out animation. The paperless/cut-out animation "I put them on the same category because they are very similar" and the traditional animation are two different process, when You are going to do paperless animation is recommendable and logic to use a program for to drawing, to paint and photo manipulation, to make Your characters, Your assets, Your backgrounds, etc, Your program could be called Gimp or Photoshop, "You can also do animation and other ton of things in those programs but they are not animation programs" anyway, the principal aim or the principal use of these programs is to produce still images, they are very good doing that. Then You have all Your assets, your characters and your backgrounds, these things are still images, they are no animated yet, You can do nothing with them, You NEED to go to OpenToonz or go to Your animation program to give them life, to create the meshes, to put the armature/skeleton to put the keyframes, to play with keyframes, to do lipsync, to do amazing stuff that You can perform, You need to go to OpenToonz to animate it, to make the process of the animation happen, all of this happening inside of OpenToonz. On the other hand, the process of traditional or frame by frame animation is different, maybe the creation of the assets in paperless could be compared with the creation of the characther sheet or background design or mechanical design in traditional animation, and also it would be better to use a program aimed for drawing and painting to work on the design tasks, now we have the character sheets, the mech design or whatever and your beautiful backgrounds painted, and now what? the traditional animation is based on drawings, a drawing over a drawing over another drawing, that's how the traditional animation process happens, and if I have to do my frames outside of my animation program wich would be the point on use that animation program? I can mount the frames of my animation on blender, i can get special effects in blender, I can put the sounds in blender if I have to chosse a program just for to mount my animation I would choose Blender over OpenToonz, not because it would be better, because I know more about blender, i have years working with blender, I´m sure that I can get all the special effects that OpenToonz has, anyway the brush tool is not bad at all, i think i should work more with it to see if I improve my results, but I think if You are making a good traditional animation software it should have first good tools for drawing, again the drawing is the base of traditional animation as tools like meshes or skeletons/armatures are indispensables for paperless animation, so I leave this request/suggestion to You.
Now I go with the programs and the why I see "as all of us" a great potential on Opentoonz:
I like to search for new tools principal aimed for illustration but also for animation thats how i found and get really excited about OpenToonz. I' m NOT looking for a drawing or painting program that can perform simple animation, I already have AzDrawing, it is freeware and believe me is the best for drawing and inking! I was looking for an animation software and openToonz appeared as magic. Fire Alpaca and Medibang are the same software it only changed the name and it is free but not freeware I think You could do animation, in fact you can do animation in any painting or drawing software but these programs are not aimed to do animation, in the particular case of medibang I read in some forum that its installer contain a virus so it made me runaway from it, and again If have to choose i stay with AzDrawing. Krita is very buggy on windows or at least it was when I test it, just check the windows krita forum, and again I' m not looking for a drawing/painting that can perform simple animation, if I have to choose again I would stay with AzDrawing it also has oinion skin. I was trying to do 3D animation and the more I learnt more I felt the need to learn traditional animation, and with it on mind I searched for animation program or tools that could be easier the process of animation, first I found PAP animation it has great tools but "in my opinion" it fails with the drawings tools and also with its "levels" system, anyway I dont like it, the other animation software that I found is TVPaint it is very expensive but I think it has great tools for drawing and animation, I' m thinking seriously on saving some money to on a near future buy a license, and then opentoonz appeared, it has rotation canvas as the real animator´s table, it has x sheet it has that powerful onion skin system you can choose which frame you want to see and which not, the onion skin system in painting programs doesn´t work in that way, opentoonz has that powerful system of columns for complex animation, You can
put the background in one column and each character in its own column,
you can draw the body of a character and animate just the arm or its
head on a separated column, You can not do that in a painting program because it takes the layers as frames so you would have only one column to work, what I´m trying to say is that opentoonz is an animation software, why not to use all these amazing tools also for traditional animation by just making more powerful the brush tool?
Thanks for reading!
