Here in Maya I have a small object that I've modeled but I want to now light it and render it.
I'm going to show you how to light this with three-point lighting and add a backdrop so it
looks nice with shadows. If you want to know how to model this object there's a link to the video
in the description. The first thing we need to do is create a backdrop. To do that click on
the curves surfaces shelf. We're going to use the bezier curve and then press the space bar
so we can see all of our views. We're going to work on the side view here. If you hold the x
button on the keyboard and click you'll lock to these vertices on the grid. So i'll click once.
Then I'll click behind and this time I'm going to click and drag to the left. Drag two squares over.
Then go two more squares over, four squares up, hold x and click and drag up two squares.
Then pan up and click one more time at the top holding the x button. Then press spacebar, q to
get back to the move tool and press space bar to return to the perspective view. We can zoom out.
With this curve selected, I'm going to go to the attribute editor and i want to click on bezier 1.
I'm going to translate this over 25 , then press enter. I'm going to press ctrl d or command d
to duplicate and then type negative 25. Now I have two curves. I want to off click then I'll click
one of them, then hold shift and click the next one. I can double click on the loft command here
or I can go to surfaces loft and click on this box. This gives me options for the loft. I want
to make sure that polygons instead of nurbs is selected and I want to select control points. Then
click loft, this gives me a surface going across but it's still kind of chunky so I want to click
on the poly modeling shelf and I can click here for smooth. I can also go to the modeling toolkit
and click smooth here. Click smooth twice and then we have a nice smooth polygon surface.
Click on the outliner on the left hand side of the screen. We can delete both of these beziers,
we don't need them anymore. We can also click here to turn off the grid since we have
a floor for our rendering. Click on q to select the object. I'm also going to close the outliner.
I can now press r to scale this object, I can scale it like this and I can also scale it in
the vertical direction as well as side to side to have a nice big object to render on.
Right click on the object and we're going to assign a new material, we'll assign a blin.
Then over in the materials we want to turn off any reflectivity and any specular color.
This way we won't have any reflections on it. Now we need to add some lights to do that we'll click
on the rendering shelf and we'll add a spotlight. The spotlight shows up right in the middle we can
press r to scale it, grab it from the center and scale it up. Since this is a Maya light scaling
it does not change the intensity of the light if you are using lights from the Arnold shelf
and you make the light bigger it will change the intensity so make sure you pay attention to that.
I'm going to go back to the rendering shelf. Then I'll press w to move the light I'll move it up,
back away. I could press e to rotate the light and aim it but there's an easier way, when you have w
or the move tool selected you can tap t. It brings you up another control so I can bring this control
out and notice how the light points at that control I can bring it down towards the object. I
could try to guess where the object is or I could press v. So let go then press and hold the v key
you'll see this little circle and then it'll snap right to the object. Then I can drag
this over and notice how the light continually points at the object and then I can raise it up.
If we press 7 on our keyboard or click this little light bulb it'll show the
default lighting setup so then we can move our light around to see where we want it to be.
Press spacebar so we can see the top view, move out a bit. We want to create a 45
degree angle of the light pointing at the object. What we have here is pretty good.
Now we need to change some of the settings on the light itself. In the spotlight shape we can change
the intensity of the light. If we change this much it's going to get very bright very quickly that's
because the decay rate is set at no decay. This is not very realistic but is useful for simple
lighting and seeing what your light is doing. We want to change this to quadratic, notice that now
the light is completely gone. It's still there but quadratic is a more realistic light setting
so that means the light will decrease with the distance away from the object, so that
means we really have to crank up the intensity. So I'm going to put in 3000 for the intensity,
now I can see my object. Another thing we want to click is this SRGB gamma. We can click this off,
this is going to be more realistic of what's actually going to render out with a png
or a jpeg. So that means i'm going to increase this intensity up to 4000,
maybe even up to 8000. Let's see what that looks like. So 8000 gives me pretty good lighting here,
I can always crank this down so let's maybe, yeah ,we'll leave it at 8000. Then I want
to adjust the penumbra angle. Look at the edge of the lighting here, if I adjust this
everything becomes more fuzzy. You see that, so we want to make this fuzzy and then we're going to
increase the cone angle. So now we have the light going all the way across the scene. We can then
make more adjustments to the light moving it where we think and notice it's always pointing
right there. Increase the cone angle even more. Then we want to scroll down and we want to select
use ray trace shadows. We're going to add some more light radius and then we're going to add more
rays to our shadow. So let's type in 20 for now and then we can adjust that to make our shadows as
smooth as we want once we have everything set up. Let's click on the outliner and make some names.
So here we have block which is our block and then lofted surface let's rename this to background
and then let's rename this spotlight to key light. First I'll close the outliner, then I'll press
ctrl d or command d to duplicate move this light over and notice it stays pointing at the second
light. I can press space bar to see the top view, we want these lights to be kind of at an angle to
each other so this looks pretty good here. Press spacebar again to go back to perspective view.
Notice that now it kind of seems over lit that's because this is the fill light and we want that to
be at a lower intensity. So if this was at eight thousand let's bring it down to at least four
thousand. Now this is just filling in this side. We can even lower it lower if we want depending
on how we want that to look but I'm going to leave it at 4000 which is half the intensity
of the key light. I'll click on the outliner again and I'm going to rename this one
to fill light. Then I'm going to duplicate it one more time by pressing ctrl d or command d.
I'm going to bring the light down press the space bar so we can see everything that's going on
and then this one I want to bring very far down. So I want it to be kind of level with the object
and then I want to move it over, so we'll move it over.
Then in the top view I can bring it kind of to the back of the object. I will likely need to adjust
my backdrop but I'll do that in a second. So here I can continue to bring it down so it's kind of
even with the object and then I can drastically reduce the cone angle,
you can see it in the perspective view that we're changing that cone angle
and then I want to move it back behind the object. This is adding, this is really good for
having reflected light and separating your object from the background. I'm going to press spacebar
on the perspective view, scroll out a bit and i'm going to scale up our background. So I'll press
q, select the background then press r and scale it in this direction.
Now press spacebar again select the light down here and then we can maneuver it how we wish.
Make sure you press t so you don't lose your focus.
And then you can see how this will adjust if I move it to the front you'll see how that
reflection, then as it goes to the back we can have a little bit of reflection in the back there.
And we're going to lower this intensity of this light a bit too. So now we have our lighting
setup we need to add a material to our block so I'll right click on it, assign new material.
I'll select Blinn, then I'll double click on the color,
increase the saturation, then click done and now i have a color on my block.
if I position the camera like this, to be able to see it more I'm going to select the block
press e to rotate and then I'm going to move it to the side like this for a more dramatic angle.
Now I can click the render view it will default to the Arnold renderer and we'll get something
here. In fact, the Arnold renderer is great but we need to increase the light intensity
because it has even more realistic quadratic renderings. So instead of the Arnold renderer
let's start with the Maya Hardware Renderer 2.0 and then we click render. And here we can see
that it's very bright what we need to do is turn off the SRGB gamma and then we can see that we
have a nice render of our piece. If we want to save this file, we can go to file save image
but we may want to change the options. Select options then go to render settings we're going
to use the perspective camera, we can also set up a renderable camera. So now we're getting our
block lit with our lights and we're getting render previews but if I want to change the angle of my
render I have to move this window out of the way and then rotate, click render again and then c.
This can be very cumbersome especially if I want to zoom out and edit the lights.
There's a better way, we can add a camera to the scene by clicking this camera icon.
This will bring a camera in, into the center here. We can move the camera back and here you can see
the camera. Just like the lights if we press t we get a camera aimer so we can aim this camera
and then lock it onto here. Remember that you have to let go then press v,
you get the little circle and then it'll snap to this object. Then I can zoom out and move
the camera to where I want it. Then I can click on the render view and in the render view I'm
still seeing the perspective camera. I need to click on render then render then camera 1.
Now I can see the view from camera 1. Notice if I click on the camera and move it closer then click
render again the object gets closer. If I move the camera over here and click render, now I can
see the object from this angle. I'm going to move the the camera over this way then click render.
Maybe not so far, move it back a little, move it this way
and then there and click render. So now I can keep this the way I want and if I move my scene around
I still can then click render and see what has happened. This is great for being able to move
my lights where I want them. So I can move this light forward and closer to the object,
click render and see what effect that has over here. Remember when we're in the preview we
want to turn the gamma off so we get a more realistic picture of what we're going to get.
The last thing we need to do is click on the settings and then instead of hd 540
we'll click hd 1080. This will give us just more resolution in our render and I can click render
to see what that looks like. This looks pretty good. I can go to file, save image and select
a png and call this rendered block and then click save .If we zoom in a little bit though notice
that we still have some jagged shadows we can adjust the settings of the renderer but there are
limitations with the hardware renderer. It's much better to use the Arnold renderer. So if we select
Arnold renderer then click render, our scene is much darker because we need to increase the
intensity of our lights but our shadows are so much clearer. I'm going to click on the settings
to drop the resolution of the renderer for preview and then instead of having the render update each
time, we can click on Arnold, open Arnold render view. Then if we click the play button and so
now we can move our lights around and the Arnold render engine will automatically update and it'll
give us a nice view, so that way we can leave this here come over and change our light shapes. So
let's adjust the key light, we can adjust this up to let's say maybe 14000 so now that's much
brighter then we can do our fill light brighter. So make this maybe 7000, so that's much brighter
and now we can see that we get these nice shadows. So then once we're happy with what we what we have
Arnold render will give us much better results and it gives you even better results if you use
the Arnold lights. So hopefully this introduction allows you to use three-point lighting
with the Maya Hardware Renderer and experiment a little bit with the Arnold render. view.
