hey this is Kevin with blender binge back with another tutorial this time I'm
gonna do this interesting looking loopable energy effect it's really cheap
really quick renders and Eevee very fast and it's probably usable for like a
number of different things you can think of so I came across this while doing
another tutorial for that bowling ball and I was like hey this would work for a
cool energy effect so here we go so the first thing I'm gonna do is I'm going to
give it some geometry that I can put this energy effect on so I'm just gonna
go add mesh and I'll use a circle and what I'll do with this is now that I
have this circle here polygon circle I'm just gonna hit tab I can hit two on the
keyboard or I can go here and I'm gonna hit E for extrude and then I'm just
gonna hit enter once and now what I can do is I can hit s for scale and just
pull it in and now I have a nice flat disc okay there are many ways to do that
that's just one of them okay it works for me works for this video
fine now what I'll do is I'm gonna give it a shader so to do that I can use this
shading tab up here cuz I'm in 2.8 or I can stick with my timeline because we're
gonna animate this thing and I can draw another window up here and just get the
shader in here so that's what I'm gonna do I'm gonna drag up a window I'm going
to say shader editor click on a little button select this and hit new and now I
have this principled psdf shader on this guy so what I'll do here is I will go to
shaded view ok rendered view over here is little icon and we're in Eevee now so
what I'll do is I'm going to do a shader on here and I want part of it to be
transparent and part of it to be opaque where the energy is so the energy will
be opaque and the rest of this disc is going to be transparent so to do that I
could use the principle be SDF shader and wire stuff into transmission and all
that but I'm going to do just a little bit more controllable way
so I'm going to select this principle be SDF shader I'm gonna hit shift s and
this shader I'm gonna change it to a mixed shader and what that does is it
allows me to use two different shaders on here so I'm gonna hit shift a or you
can do add either one works shader and the first one I'll call in is a
transparent shader and I'll plug that in down here and then I'm gonna hit shift a
again and I'll go to shader and this time I'm gonna use emission because its
energy and it gives off light and that's all cool so I'm gonna plug that into
this and what I can do now with this is I can control my energy effect you're
just using factor now so I'm gonna plug a texture into factor so I'll go shift a
or AD and I'll say texture wave texture and this is where I got from the bowling
ball and I'm gonna go factor to factor and now what I'll do so we could see
this is this transparent I'm just gonna drop that down okay to black for now
okay we're gonna probably play with that again later right now just so I can see
what's going on here and I can now look at my object and say I have these wave
textures okay I have this band so if I change band to rings it starts wrapping
around but it's not looking like it's wrapping around the way I want yet so we
have to tell it to do that so in order to tell it to do that I have to plug
something here into the vector so I'm gonna go add input okay because we want
to input something into the vector to tell it where we want it texture
coordinate now for those who are advanced you can use node Wrangler here
and just get this whole setup right off the bat but I'm just gonna do it this
way for anyone new who just wants to learn so I'm gonna take object here okay
so object plug it into vector and now I have these nice concentric rings going
around this circle and I can also control that with a mapping node if I
so I can hit shift a and I can go to vector and say mapping okay get this
massive thing that comes in here and now what this does is it allows me to just
play around and you know tweak it from here if I want so what I'll do now is I
can play with this scale I can do it in two places now scale over here okay
changes the texture while I'm here okay and or scale over here so I'm just gonna
scale it down and get this nice nice ring kind of wrapping around like right
there it's probably good and now if I play with this distortion I can start
getting some distortion okay detail detail scale and I can just really start
playing with that and getting this look that I want and now what I can do is I
can control how much of this white I want just by putting a ramp in here so
watch this if I go add and I go converter and I say color ramp and I
throw that in I can now bring the black up and start controlling just getting
that nice ring in here and it's kind of arbitrary you can play around if you've
followed me exactly then you'll probably get this exact look play around and
you'll start seeing this effect right so now you can play around and you can get
this really interesting looking energy effect and we can we could pull it back
off the wall a little bit more by just tweaking this just play with scale a
little bit and just kind of get it in there and if you get like little things
on the edges that's just that's the effect that's fine you can play with
this to your heart's content and totally isolate that out if you want but this
this will work pretty well so now if I hit render you see that I get this ring
with this thing on it and if I go to alpha you see I have this whole alpha
thing here so we're gonna go ahead and get a
nice-looking transparent thing going now so to do that we have to go to a couple
of different places the first being we have to go here to
render film and say transparent and that knocks out the background so if I render
now you see that I have my alpha okay it's not all white anymore now it's just
this which is which I want and next we're going to go to this transparent
okay we can pull that back up to white and what I can do is also go to material
blending mode alpha clip and what that does is it allows us to render and now
you see here my alpha and my color and color an alpha it's just getting this so
I can composite this over anything I want now so now I can just go ahead and
animate the thing right so I can I can animate my rotation all right and these
different rotations give you different effects over here and then the Z
rotation kind of pulls it around so what you could do is let's say I just want
like a hundred and forty-four frames so I'm gonna go here to fifty and type in
say 144 about six seconds and I can right click on the Z and I'll say insert
insert single keyframe or insert keyframes and then I can go out here and
say 358 so it's just short of a full circle okay
and I can say right click and say insert keyframes I can go here and I can do
like 358 if I want there I maybe 358 there right click replace keyframes
and now I have this animated electric kind of looping effect and you don't
need to light have all of this going but I'm just putting it on there for now so
now what you can do is just work on the look right so I can just go to my
emission maybe give it a yellow I can go to Eevee settings turn on bloom and I
can take the emission strength turn it way up if I want and there you have a
loopable and you can see here if I go out here it'll loop energy effect and
that little pause in the middle there that's just one of these things going so
like I can take like the Y here and say let's say clear single keyframes out and
now I have a nice looping effect that's not reversing on itself and you're
getting these little things too so you could always go ahead and tweak these
out if you want but this gives you a really interesting little effect and
what's kind of cool so if I go 0 and I go over here to view lock camera to view
I can even just pull this thing up if I want and there you go and some other
cool things that you can do with this being is just geometry alright
you could add a modifier so like I can add like control to and smooth this
guide out and then I can also go add modifier and I could say like solidify
and add some more effects to it so if I were to actually take this thing and set
the camera and the rotation so let me just do that really quickly here my
camera I can say alt G and alt are that puts it right in the middle and then I
can wrote the camera up 90 degrees here so check
this out right 90 degrees it'll face that way I can pull him back so just go
to the move tool pull him back a bit now this guy okay I
can rotate 90 degrees here and maybe I can push him down the Y a little bit so
now you're staring directly at it and you can start playing with these things
and getting like all kinds of really cool effects using like solidify ok so
here's one with the same effect and all I did was take this guy and you could
see here I just added a solidify modifier pulled the thickness down a bit
and then duplicated him scaled this guy down rotated a little bit and then just
like up the bloom tremendously and we get this like really interesting really
cheap kind of motion graphic II stylized fire energy ball effect and so you could
see that this is pretty useful for a whole number of different things and I'm
sure you can think of even more than I've thought of here so hopefully with
that you got something out of this tutorial if you did hit like subscribe
share it and I'll keep making more and I will see you in the next one thanks bye
