Blender 2.8 Grease pencil animation basics

all right we're gonna try some 2d animation here I'm going to show a couple of different ways in a hopefully fairly quick little video I'll select 2d animation here from the screen we could also go up here and go file new 2d animation but we're good to go and you can just start drawing right away all right I'm gonna undo that though because let's say we want to draw over top of an image we want a background image to use this kind of a guide so what we need to do is we need to get out of draw mode we'll go to object mode nothing should be selected but what a twice just to make sure and we're gonna go add image background now go to go and find one I think I got one set here there we go we got Donald Duck in the background and what we'll do I'm gonna scroll out a little mouse wheel I can go to N and and once I'm inside of n what I can do is actually just drag the x position here the Y to scale I'll bring it down a little bit that's good and my set position is well the vertical position once you got that set where you want it I'll hit and again that gets rid of that that menu and now we can start drawing although when I look at that image it's a little bit too bright for a background image so what we can do is adjust the transparency and you notice nothing happens until we click on use alpha so we'll just drop the Alpha down in that a little bit so that we can actually see the drawing over top okay so how do we draw if we go back up here to object mode notice that we can no longer see setting for grease pencil or for draw Oh aha so what we need to do is click back over here on stroke okay on the right hand side and when we do that that should enable that layer and that's a layer we're gonna be drawing on top of and so we can select draw now and here we go and I'm just gonna draw right over top of here this is gonna be my my Donald Duck just give me a second here it shouldn't take too long and I'll close the likeness is going to be I haven't been doing a lot of drawing lately and almost done okay I think that's pretty good that's excellent actually it looks just like him okay so I'm finished at my drawing and maybe what I want to do is hide that background so I can click up here get rid of it and then we can just see my my masterpiece so the first animation now what we're gonna do to make this thing animate is go here to the modifier properties and we're gonna add a modifier a grease pencil modifier and it's gonna be build now the default looks like it disappeared didn't it okay well hang in there the default length is 100 so we'll go to frame 100 and it magically reappears in fact what I'll do is I'll set and the length of this the end frame to 100 and all I do now is go back to beginning hit the spacebar and what that does is build our little animation and we've already got our first method of animating there we go there step one which is a build okay let's go ctrl n we're gonna make a new 2d animation we're not gonna bother saving that and we're here ready to roll again so let's draw once again and let's say that we want to animate this character so maybe we want the smile to move maybe we want different things to happen let's go to frame 10 or 20 up here and I'm going to switch to object mode and actually I'll go back to frame 1 first of all and I'm gonna insert a key for location rotation and scale then I'll go to frame 20 I'll grab the whole thing I'll rotate a little bit and I'll scale a little bit and I wanna sort of key for location and rotation and scale now if I play that back we've already got an animation and a tweening the in-between frames have been created for us automatically this is brilliant there is a little bit of a problem here though well it's not really a problem but what if we want to actually say animate the mouth whenever I try to grab an individual vertice I'm not able to do that and that is because of a setting up here a little fine little setting we can either select now there's three different modes and we're in the middle one which is selecting all stroke points we just want single stroke points so what I'm gonna do is go down here and first of all enable that setting and now you notice I can grab a single one at a time again if I go back to this setting it's all or none so I can grab just the mouth and move it but that doesn't really help me by the way I should be on frame 20 I'm not sure what I did there but that's okay so what I'm gonna do is again go back to single point I'm gonna grab this point here and I'm gonna pull it but look what happens it's messy moving one of these vertices at a time it's gonna take forever well are really interesting and really awesome tool we can use this proportional fall-off if I click this button and now grab it watch what happens okay that's a little bit big I'll use the scroll wheel and as I scroll what that does is change the the the influence the area of influence as I move this so if I drag it way out to here and increase the circle by scrolling look what it does it has a much much larger impact and as I go as I make that smaller the impact becomes smaller as well too so I'm gonna do something like like that okay and I'll select diversity over here as well - I think you get the idea we're gonna make him look kind of sad and again increase the area of influence and that's pretty good and I can grab that again the end and and bring it right down to a small point like that okay all right so we've got everything done but look what happened it automatically put a key point in for those changes we made but it jumps from this and from jumps from frame 19 to frame 20 so how can we make that happen how can we tween this well we simply select one set of points we go interpolate sequence and now if we play this back look what happened we go from a smile to a frown so hopefully this gives you some help with possible ways to animate using 2d blender obviously it's a very overly simplistic and demonstration but we did cover quite a number of different tools that you might be able to use I'll just hit the play button on that and you can see how it moves in real time by the way another way to look at this would be to go to we're in the dope sheet now but to go to the timeline and the timeline should also give us a display oh and actually while we're here what I think I'll do is select these points and use shift D shift D is duplicate and we'll set our end frame to 40 now and let's just see what happens so down and then moves back up again oh but we have a little problem with the mouth look what happened there it didn't do the twinning for us so we'll have to go back to the dope sheet and if I could figure out how to do this there we go that's better and from 40 we're gonna have to go up here to interpolate sequence once again and it didn't like that because we don't have a point here if we want it to - to smoothly transition back what we would have to do on frame on the last frame here is actually move the mouth back to its previous position and to do that we hit the tab key we'd select a single vertice make sure you got the right select mode ready to go wait grab increase the area of influence again we won't have to do this in two stages grab it again shrink down the area of influence there we go that's better it's not gonna be perfect but that's okay grease it first and then we'll grab it a second time with a smaller area of influence proportional fall-off and now with this point selected we can go interpolate sequence I'm hoping that we're gonna get some little smoother the only jump now is in between frames 0 and 40 when it restarts again alright that's all I got hopefully that gets you going with some animations / note
