hi guys and this video tutorial will
work closely with extrude tool to show
you how to use it so let's go ahead and
create a new solid you can do that by
pressing create empty plane button now
let's just draw any mask and create
surface as you can see now we've got
extruded surface with mask parameters
for example now you can change the depth
of extrusion by simply changing the
depth size value you can also change the
direction of extrusion by setting a
negative number
mark front face and back face to close
the front and back halls sometimes when
you do extrusion gaps can appear between
polygon edges if this happens you can
fix it by increasing mask offset now
let's draw a round mask to make it
linear click make a linear path button
if you agree to leave all vertices the
plugin will leave them adding new ones
according to the amount you set here you
can see it more clearly now if you don't
agree if the plugin will only add new
ones according to the specified amount
so you have plenty of room for a
decision making here what's also
interesting is that you can extrude two
masks at a time
if you put the mask inside another mask
change the mask mode to substract and
click create surface you'll get yourself
a surface with a cutout inside you can
also cut multiple holes at the same time
like so
the skew value allows you to tilt the
extruding direction see I'll make a 3d
layer to show it more clearly to you
to tilt up or down simply add value
right here okay great now you're
familiar with extrude tool parameters
now let's practice a little bit okay
let's try and project this arc passage
click find camera and adjust the
parameters
we must enable the right side of the
grid okay cool
now select both layers and click create
projection click pre-compose specify the
number of copies just to double-click on
projections scene 2 now we need to
create the back side so uncheck all
sides but leave the back 1 then click OK
move down a little okay the back side is
ready now go to projection scene 2 we
need to create the bottom surface to
help us generate the arc passage
position so duplicate generate position
control then generate left and right
wall position now select both
controllers go to tools and click
generate plane from points good now we
have 3d solid with the arc passage
position so now we can mask and extrude
the passage now let me show you why it's
so convenient when you create position
with two points and find the objects
orientation here we have a street and
some buildings if we generate a position
from two points for the left building
and create a surface we'll get a surface
with the same angle as the building's
facade and the actual image so what
we'll do is we'll draw mask to get the
outline of the facade
let me change the mask collar to see it
better now we can extrude and create a
building model right here right on its
spot this is a great solution and it
really simplifies the whole process
because you don't need to do all that
long and boring positioning so that
saves you quite some time I move the
camera so you can see the result more
clearly okay let's get back to our arc
passage right so now we must make the
entrance to do it quickly disable this
eyeball right here now you can also hide
the grid if you want to and the new
version of the plug-in it's totally
possible
okay let's do it
good it's now time to extrude select the
mask and open extrude tool set depth
size to 20 hundred and click create
surface as you can see the left side
lines are okay but the lines on the
right side not so much well we can fix
this using the skew option so delete the
created surface and make a new one by
adding the skew value now it's all well
actually now we can animate the camera
not bad but let's push back the backside
plan a little so it looks more realistic
free render again
yes that looks much better okay so now
let's adjust the camera one more time
okay perfect to prevent unwanted
artifacts from popping up during
animation I edited the image in
Photoshop then I saved it as a separate
image and replace the projection image
in projection scene to
select lamp in Photoshop and save it as
a separate image the news helper grid
properties and trade bottom plane and
projection scene to then generate land
position and import the lam image adjust
it
okay now let's free render great now all
there's left to do is to erase the lamp
from image in Photoshop and replace
projection image and projection scene
one you can definitely do it yourselves
well that's all for now thank you for
watching we'll see you in the next
tutorial
