Hi and welcome to the Deep Glow version 1.3 Update tutorial so we've done a lot
of work and rewritten a lot of deep flow just to make it a lot easier to use and
harder to get bad results essentially so the main complaint that we had is
quality control settings weren't intuitive and there were really easy to
get bad results with so that was the main thing that we've been addressing
now let's just go ahead and add deep code this is what it looks like at its
default settings and let's jump straight into the quality tab you'll notice a few
changes the first thing we have is this order iterations feature so if we
uncheck that you'll notice the familiar glow iterations and that's what we had
in the previous version but now the plug-in is gonna intelligently take care
of how many iterations you should have so that you don't need to worry and that
you'll always get the best result as an example of that let's just jump down to
a really low radius of say 50 and let's turn order iterations off and we really
won't notice much difference between 6 and 10 iterations so at low radius
higher amount of iterations is really just wasteful if we were to increase the
radius to the max of 2000 we would see this ugly result here that 6 iterations
is definitely not enough and we can't need 10 order iterations is going to
take care of that and it doesn't matter what your radius is set to it's going to
choose the most efficient and best-looking settings one situation
where you may need to disable the auto iterations and change things manually is
if you've got something that's really fine detail for example I've got a two
pixel stroke here the detail is very fine and if we turn on deep glow with
water iterations we'll see that it's not really enough we can see if we turn off
the sauce opacity from 0 to 100 we can see the source very clearly there and it
just doesn't look very good so in this situation we might want to disable that
and increase the glow iterations to the absolute maximum but other than this
situation order iterations should perform very well for you the next thing
we've worked on is the steps so now you should really never need to change the
step multiplier unless you're going for like a really funky stylistic result in
the previous version if you had some very extreme aspect ratio
you would need to then massively increase the step count however now
we've made this much more efficient and it doesn't matter what your aspect ratio
is the steps are going to be perfect for you
the downsample amount works similar to before and that is that for each
iteration that you have each buffer gets a bit smaller the problem was that at
very low radiuses that caused some really ugly artifacting and so now we've
got some extra checks and balances to make sure that those really low res
buffers don't get displayed the only thing to watch out for is if you have a
really low down sample amount and a very high amount of iterations it's not going
to be able to display all those federation's because they're just
through low Reds and so you'll see here that the difference between 80 percent
down sample and 50 is drastic because of 80 percent were actually able to show
all 10 iterations but at 50 percent down sample the last iterations will be so
low res that it would cause really disgusting aliasing a value of 80 should
suit your needs for nearly everything the only time I would change this is if
you're getting temporal flickering as you've got animation or if you're doing
a really low step stylistic result increasing the down sample to 100 will
give you a much cleaner result because you can actually see the detail on each
step other changes we've made is the input threshold and threshold smooth now
default to zero we've also removed this smooth blending option and said that as
always on because the feedback we were getting is that that produced a better
looking result people were happier with that so we thought well let's just
always have that turned on so that's it for this update and in the next update
we're gonna add some really cool stylistic features we're gonna have an
angle for the aspect ratio we have some more options for these funky looking
step results as well as a mask for the input so stay tuned for those in the
next update of deep claw
