hello there and thanks for joining me
I'm Kirill Peter master Aaron Rutten and
in this video I'm gonna be showing off
the rock brush pack for particle shop so
let's go ahead and use the rock brush
pack to add some interest to these rocks
because these are just boring and flat
and white so let's see what we can do in
the particle shop panel let's choose
duplicate active layer which would be
this layer here and we'll click on
launch particle shop with particle shop
open we can click on the rock brush pack
and here are all the different Rock
options down in the bottom right let's
start with the granite preset we want to
make sure our brush tool is selected we
want to click on the toolbar on the left
to open the color wheel and I want to go
ahead and click on the pin button to pin
the color wheel so it stays fixed on the
screen now let's pick a color I'm going
to choose kind of a bluish gray color
like this and I'm going to paint all
around the area of the rock that I want
to color in don't worry about over
painting just make sure you cover the
entire rock now if you want to resize
your brush you can hold down ctrl and
alt on your keyboard and you can drag
your brush bigger or smaller that'll
give you some different results for the
size of the particles that you're
spitting out as you can see here so I
brush bigger I get bigger chunkier
results I make it smaller then I get
smaller finer grains if you use pen
pressure on your tablet you can control
that size as well if I use a lighter
pressure I get finer grains if I use
heavier pressure I get bigger broader
grains I'm gonna select another brush
which is tonal light and I'll select a
lighter color and be kind of a yellowish
cream color like this then we might
brush kind of small and I'm just going
to tap with my pen or click with my
mouse and make my brush even smaller I'm
going to do that up here on the slider
and I'm just going to reduce it down to
1
and essentially what we're doing here is
just creating a nice Rock texture and
will conform it to that rock form that's
underneath it so to do that let's click
on 'save down here in the bottom right
we want to save only the brushstrokes
and that puts our brushstrokes on a new
layer I'm gonna call that new layer
granite and I'm gonna set the composite
method of that layer to multiply next we
want to add a mask to that layer by
clicking on the mask icon make sure
block is selected and we'll switch to
our brush tool the preset that we want
is a soft edge brush like this and we'll
just use that to paint right along the
edge don't worry about if you over paint
the rock that's okay but just clean up
anything that's spilling off of the rock
now I'm gonna switch to white I can do
that by hitting X if my background color
is already set to white and X is really
handy to switch black and white really
quickly this is very helpful for masking
so when we were painting with black in
the mask we concealed some of that
effect but if we want to bring it back
we can use white to very carefully paint
back along that edge with a smaller
brush that way we get the entire rock
covered and again if you paint over the
edge don't worry about it you can select
black again and it can be a
back-and-forth process until you get the
exact mask that you want now if you find
that that effect is too strong you could
also go to the opacity and you can
reduce the opacity something like that
looks pretty good for that rock let's
change up some of the other rocks using
another preset so now that we have
multiple layers in our composition
rather than duplicating the active layer
let's duplicate the visible layers below
and merge with the active layer so
that's going to take all of these layers
into account and this time let's select
sandstone I'm going to select a
sandstone color which would be kind of a
peach color like this and once paint in
some streaks that are following the
curvature or the contour of our rock we
can make our brush smaller if we want
finer streaks like this
but again don't worry about painting off
of your object here better to over paint
than under paint let's change up our
color a bit
basically what we want are little
stripes something like that looks pretty
good let's go ahead and click on save
we'll see if only the brushstrokes and
just like we did last time will change
the composite method I'll choose
multiply and we'll add a mask to that
layer we'll make sure black is selected
we'll select our brush tool
now if you want to edit that rock effect
you can continue to do so here in
Photoshop I'm gonna click back on the
layer which takes me off of the mask and
now if I want to I could use some of the
regular Photoshop brushes to paint here
on this layer as well if I wanted to
enhance little cracks and do things like
that I can also edit the colors by going
to image adjustments and hue/saturation
it's not bright enough I can increase
the saturation I could make it darker or
I could make it lighter and I can shift
the hue if it's not the correct to you
something like that looks pretty good
I'll click on OK now I have that nice
sandstone effect these rocks are
beginning to look a lot more interesting
so go ahead and do this remaining big
rock here let's try pour fiery and let's
pick an interesting color like this now
if you're using a bigger brush you're
going to get bigger speckles if you use
a smaller brush you're gonna get smaller
speckles and again you can use your pen
pressure on your tablet to make those
speckles bigger or smaller if I press
down harder I get bigger speckles if I
press down lighter I get smaller finer
speckles so I can really quickly and
intuitively go in here and just paint in
this nice organic looking rock texture I
can also just tap with my brush to
create little spots like this now we
have this really interesting rock
pattern we could add some other colors
to it as well
let's go with that we'll click on save
will save only the brushstrokes again
will change the composite method we'll
set it to multiply we'll add a mask if
masking with the airbrush isn't your
thing you can also use the lasso tools
for example I could choose polygonal
lasso
then you can go to select inverse to
invert the selection switch to black and
then Phil will fill that with black ctrl
D to deselect not give us a pretty good
mask we'll still have to clean it up a
bit with the brush
again if we want to edit that rock we
can click back on the layer we can go to
image adjustments hue/saturation if I
want a more exotic rock color I can
shift the hue that's kind of an
interesting color that you wouldn't
expect to see way up in the mountains
and reduce the saturation if I want to
blend it in and make it a little more
subtle let's go with something like that
and now we have three very interesting
rocks now what if you want to create
your own rocks that don't exist in the
painting let's take a look at how to do
that I'm gonna create a new layer I want
to call this rock I'm gonna switch to a
hard edge brush and let's select a rock
color something like this will have this
rock setting right up here
so once we've painted in our Rock shape
let's go ahead and lock the transparent
pixels by clicking on this icon here I'm
gonna select a darker color and I'm
going to switch my brush to that soft
edged airbrush make my brush bigger we
can see that our lights coming from the
top right in this painting so on the
bottom left I'll just add a little bit
of shading here let's make our color a
bit brighter let's put in a bit of a
highlight on the side here facing
towards the light sample our sky color
will put a little bit of reflection on
the backside I'm gonna pick a darker
blue color I might add in a bit more of
a shadow here
and maybe just a few more highlights as
well so now we have our basic rock but
if we want it to look more interesting
we can go ahead and duplicate visible
layers below and merge with active layer
with that rock layer selected let's try
carbonate this time and you use a
smaller brush and an almost white color
to paint over my stone let's click on
save
we'll see if only the brush strokes I'll
just name that layer carbonate let's
change the composite method to overlay
let's hold down ctrl or command we'll
click on the layer icon for the rock
layer that'll put a selection around
that layer and on the carbonate layer if
we create a mask that's going to
automatically crop out the background
now we can play with the opacity you
want to blend it in a bit more and we
have that nice sparkly crystally looking
rock and again if we wanted to continue
to edit either of those layers we could
do that we could click back on the rock
layer and if we wanted to use our brush
to put in some brighter spots we could
do that just by painting and we're
painting underneath our carbonate
texture here now if you don't want your
layers to be separate you can merge your
carbonate and your rock layers together
by selecting both of them using shift
and you can hit ctrl or command E to
fuse them together into a single layer
now if you wanted to you could switch to
your eraser and you could reshape your
rock if you want it to be a little more
pointy something like that looks more
organic I'll show you another way to
create a rock that's more polygonal
let's select the polygonal lasso tool
once have a rock up here it's more
pointy like this I'm going to create a
new layer for that select a rock color
will fill with that ctrl D to deselect
let's use that polygonal lasso tool to
go ahead and divide our rock I'm going
to select a dark blue color I'll select
my brush preset I want is a soft edged
airbrush I only want a fairly large
brush I want to lock my transparent
pixels and I'll be able to paint only on
that rock
I make it
your side like that facing away from the
light the lights coming from the top
right in this case control DD select
back to that plugin or lasso of this
little corner facing right towards the
light so that'll be the brightest in
this side here will be the darkest since
its facing away from the light the most
control be to deselect and now we have
our more polygonal shaped rock let's go
ahead and unlock the transparent pixels
let's switch to our eraser and if you
want you can erase a little bit here so
it's not so perfect
I'll just name this layer pointy let's
go ahead and duplicate visible layers
below and merge with the active layer
let's try adding some cracks using
basalt I'll select kind of a dark gray
color like this we can tap to add some
little fractured shapes here that
creates kind of an interesting texture
on that rock let's go ahead and launch a
particle shop again using that same
preset and let's select a pie rocks a
night use kind of a dark grey color like
this and we'll just paint over the whole
thing some lighter and darker colors
and we'll add one more layer of texture
to that let's use marble and we'll use a
very light color use a small brush just
to draw on some little Marbley patterns
here
I've gone ahead and just grouped and
named my layers here so it's all nice
and organized and now if we do it before
and after you can see the effect that
the rocks particle brushes had on this
composition it looks a lot more
interesting now and really quickly I
just want to show you the remaining
brushes and how they work let's try coal
for coal you want kind of a dark gray
color like this and you can make little
chunks of coal gypsum gives you this
nice streaky effect if you wanted some
more crystally looking rock with a
directional grain Limburg it-- I suppose
was named after cheese or something it
gives you these nice geode looking
effects if you tap with your pen or you
click with your mouse let's try an
alright and you can see you get this
nice rocky looking texture with all
kinds of different colors in it
pegmatite you can use to tap and create
these little crystal e effects pumice is
very helpful for creating little bubbles
and holes in your rock you can tap and
hold with your brush too to create
little holes like that
let's try syenite that gives you a nice
rocky texture like this and that should
give you a pretty good idea of how to
use the rock pack here in particle shop
