hey this is Kev from blender binge back with another tutorial this time we're
gonna be creating this cool pixelated logo reveal that the pixel lights on the
way in kind of solidifies warps a little bit and then settles in and then warps
out and disappears and disintegrates it's a pretty common looking effect that
we can do it after effects pretty quickly but I'm gonna show you how to do
it in the free brand new blender 2.8 and you're gonna be able to do it and it's
gonna be cool and you're gonna add another skill to your set it's gonna be
great and you're gonna save the world it's gonna go awesome or whatever let's
jump in so the first we're gonna do is give it something to put this logo on so
I'm gonna go add mesh grid and then add grid down here I'm gonna say X divisions
and Y divisions I'm gonna click and drag over both of those and hit 60 and then
hit enter okay and if you see I go here and hit tab it's subdivided to that
pretty nicely and that's gonna play into our effect really nicely now so the
second thing I want to do here after I create the grid is to set up my scene
file a little bit so I'm gonna go over here to rendered and then I'm gonna go
over to so I hit this little button says rendered and then I'm gonna go down here
to this little camera icon and I'm gonna just turn on bloom and that's pretty
good for now and let me just drag this up a little bit so you see the timeline
and now we're gonna go ahead and add a texture that's our logo onto this grid
so in 2.8 we have these workspaces I'm not going to go ahead and use it I'm
just gonna do it the old way because I want everything in frame so we can see
everything in one view so I'm gonna go down here my master ends to a little
crosshair I'm gonna click I'm gonna drag up and I'm gonna change this little
button here editor type to shader editor and then what I'm gonna do is I'm gonna
click on this guy and I'm gonna hit new now the more advanced people if you want
to play with principled psdf shader and and and use emission on here and do all
that stuff go ahead but I'm gonna do a really simple setup that allows us
independent control of everything and it's going to be a little bit better for
what we're using this for so I'm just gonna go change this principle bsds
shader so I'm to make sure I click off its and nothing
selected then I'm just gonna select this guy okay important you don't have both
of these selected just as one hit shift s shader and then emission and now I'm
gonna plug an image into this so the more advanced people feel free to go and
use rain the node Wrangler and you know control shift T all that stuff if you
want that's cool anybody else following along who doesn't
want to go set up node Wrangler right now we're just gonna go add we know go
texture we're gonna go image texture and I'm
gonna plug color to color and you see it turns black that's because we don't have
anything on there so I'm gonna hit open and I'm gonna load in a texture okay so
I grab this texture off Wikipedia you can go there just type in blender logo
it's on Wikipedia and it's the logo for blender okay we all know this one and
what this does is it just gives us a basic shader admission where it's just
now controlled strictly by the emission everything else is black and we're just
gonna black out the background anyway I'm not gonna worry about alpha channels
and all that for now but we're just gonna black it out and we're gonna get
the effect so to do that I'm gonna go to world color and just turn this to black
and now let's just set up our camera so to do that I'm going to you know maybe I
shouldn't have done that yet will you just turn that up a little bit let's go
back grab our camera and I'm gonna zero it out so I'm gonna hit N on the
keyboard and you'll see that this little thing item okay you see the rotation of
the camera and the location we can just hit alt R that zeros out the rotation
and alt G zeros out the location see that and then all I do have to do is
pull this up on the wall on the Z a little bit hit zero on the keyboard and
just pull it up so it's about there and now I can go back this color here and
turn that to black so the background is now black and there we have a nice glowy
blender logo so now the the third part of this video we're going to do the
actual or fourth part we're just gonna do the actual effect so what I'm gonna
do is I'm gonna go to modifiers over here I'm gonna say add modifier and I'm
going to hit build and it disappears but if you hit play
you see it does this like kind of scanline rendering look okay a very very
very basic look that's cool it's just building these building these these just
grid up in a line pattern so you can see if I select it you see like how it's
building it up line by line there right so what we can do is I could say start
all right we have 250 I'm gonna say 240 all right our animation will be 240
frames and so about 24 so about a second in I'm gonna start it so this start on
the modifier it says it 1 I could say 24 and now it won't start until now so
it'll start at 24 and I can say length maybe 50 frames and it'll only go 50
frames so you see goes up feels pretty good and it ends around here right
around like 74 okay so that's rolling up now now we can do is I can add another
one of these builds by just hitting copy okay I just get a copy of that and now I
can hit randomize and now if I go down here you'll see that it starts
randomizing as it comes in so if I like hide this one right you'll see that
it'll just randomize as it comes in but I also want it to have that effect of
building so I turn it both on and now I get this nice and you can even stretch
this out like 60 to randomize it even more and now you'll see that it finishes
and then it just comes in but for this tutorial I'm gonna put it back at 50 so
it matches and there now our effect is there so all we have left to do is give
it just a little bit of an interesting warp look so to do that I just go
modifier again and hit wave and over here I have speed and height speed I
don't want it to be this is like really fast
I don't need it to undulate like that that's just crazy so I'm gonna take that
down point oh five right and let's see if I deselect that that looks
better so by 96 it can flatten out or by like a
hundred it can flatten out right so what I'll do for that is I'll keep it at
about ninety the height so what I'll do is I'll right-click on height and I'll
say insert keyframe and then at about a hundred I'll say height to zero and I'll
do insert keyframe so now if I hit play
boom nice kind of just finishes off and boom so I could even like go here let's
say 70 and 70 and it's still building as it settles in
so that might look a little bit better right there we go let's look at that
nice okay so that looks pretty cool and then I could say from about a hundred
hold it for like two seconds it's like 148 and what I could do there
is again with the height all right I can hit insert keyframe and then by
like 160 I could put the height back at like 0.5 so now it'll undulate again so
insert keyframe so it'll stop undulating right hold for two seconds then it'll
start undulating again and then like say like 180 I can just add another one of
these builds in so modifier build and that's just gonna that's just gonna
allow me to disintegrate it on the outright because we're just integrating
it in these guys are working I don't want to keyframe these because I like
what they're doing so I'm gonna add another modifier on the bottom of this
right so if I like collapse these you could see it better
okay so here's build one build two so now what I can do is add modifier and I
can just do like one build out here and I could say start frame where we're at
now 180 and hit reverse and randomize and now what that'll do is over a
hundred frames it'll just blank out but we want it to
be way faster that that so by like 200 we want it gone so
if you just say 20 frames and there you go you disintegrate and now our
animation can only be 210 and we only need two hundred ten frames wait so
watch this hit play it builds up does its thing settles in undulates goes back
out so let's just start this last build at like 150 that way when it starts
undulating it starts breaking up there we go and then what we can do
lastly is just up the strength of this guy the bloom alright so it'll come in
be really hot here there we go and when it starts settling in it's at about 90
we could set the keyframe here once it settles by like a hundred I could pull
the strength down to like point no one is good insert keyframe and hold it
until it starts going out again right so like 150 insert keyframe and then by
like 160 I could say you know bump it back up insert keyframe and then it
fades out maybe 160 let it glow a little bit hand fade out so here we go I hit
play there it goes okay so let's render it and see what it looks like and to do
that just to simply go to this little printer icon and I'm gonna go and I'm
gonna render it so I'm gonna hit this little tell it where to save it right
side of this little area logo reveal and my temp folder whatever I'm just gonna
because I usually trash these when I'm done with it so logo revealed mp4 make
sure you type in mp4 hit accept and then file format I'm just going to say ffmpeg
video encoding will be h.264 and mp4 and then I'm gonna hit render render
animation and we'll come back when it's done okay and we're back and
here's the logo reveal simple little effect so I'm gonna go ahead and tweak
it and do one more render and we're gonna take a look at it and then I'll
tell you what I did to make it cooler okay and we're back and here it is
with the somewhat cooler looking effect and all I did was just take the plane
and subdivide it one more time selected the grid hit tab went to edge
hit subdivide once and just subdivided it more and now it just gives it a much
cooler look and much more like pixelated digitally but more like a particle type
effect and then over here it just kind of Blanche's out again so that's it so
hopefully you got something out of this video it like subscribe share it and I
will just keep making more see you next one bye
