1 Tutorials Poser Mirror Tutorial em Qua Jan 26, 2011 12:01 am

The
mirror effect is a very nice effect for any type of art and it works
especially well when creating art with Poser. It is slightly different
than the normal reflective tutorials that you may come across on the
internet because the image is not just reflected, it is mirrored in the
same way as if you were looking in a mirror. But before we get into the
many ways in which you can use the mirror effect for Poser, we'll take
a quick look at how to create this effect using both the regular Poser
lighting and the indirect lighting feature found in Poser 8.
To
make this tutorial even easier, we are going to use 1 light setting
that comes with Poser 6, Poser 7, and Poser 8. We'll also use the
primitives that comes with poser so that you can get the full effect of
how the mirror effect works. Then at the end we'll apply the mirror
effect to a scene and show this process in a step-by-step video so that
you can see us create the effect. Now let's get started with this short
and easy to understand tutorial.


Step 1: Preparing the Scene: Open a New Poser Work Space


For
the first step we are just going to use the default light settings that
pop up when a new workspace is opened. Delete light 2 and light 3 then
change light 1's color to white. Next we will add a High-Res(High
Resolution) Square or a one-sided square to use it as a floor from
Poser 8's primitive props. And we will add a High-Res Ball to the
scene. At this time your Poser work space should look similar to the
image here. It is recommended that you scale both the Square and Ball
to a slightly larger size if needed.



Here is what the image looks like when it is rendered without the mirror effect. As you can see below things look fairly gray.


Step 2: Add Reflect Node to the High-Res square
<table border="0" width="100%">
<tr valign="top">
<td class="style12">For
the second step of this process we will apply the mirror reflection
settings to the high-res square in our scene by going into the Material
Room. This will be done in the Advance Materials section of the
Material room. You can access this by clicking on the Advance tab found
in the Material Room. Your Material Room Advance settings should look
similar to the image below.
Material Room Advance Settings for High-Res Square. (click on the high-res square to get it's material settings)


As
you can in the image above the clothplane (high-res Square is selected
at the top as the object). Has a white Diffuse_Color setting. We want
to change the Diffuse_Color to black and then move the the
Reflection_Color and set a node by clicking on the plug next to the
Reflection_Color option and set the reflection setting by following
these steps.

  1. Click on the plug next to Reflection_Color to choose the node
  2. Mouse over New Node-> Lighting-> Raytrace-> Click on Reflect as shown below.




Your Material Settings should now look like this:

Now
lets render to see what is going on. Before you render make sure your
render settings are high enough to have the raytracing activated.
Reflect only works when the raytracing is activated. Move the marker in
the render settings to the right until a check appears in the
raytracing box. Now you are ready to render. Your render should look
like this.

Ok
at this point we have a reflection effect but not a mirror effect
because we cannot see the back of the ball that the light isn't shining
on. In addition the part of the graphic that we can see isn't very
clear as it would be in a real mirror. In order to get the mirror
effect we will need to change the Diffuse_Color and the background
color in the reflect node.

<tr>
<td class="style12"> We
will change the Diffuse_Color in the advance material room settings and
explain what happens when we change this setting. Changing the
Diffuse_Color in the advance material room setting will change the
color of the High-Res square except for one color; white. We have
provided some sample of what happens when the Diffuse_Color is changed.


Now
that you have seen how changes in the Diffuse_Color setting affects
your renders, change it to black. Changing the Diffuse_Color to black
will sharpen the reflection. We are still unable to see back reflection
where the shadow is, so we have more more setting that we will need to
change. When you think of a reflective surface you have to think that
the surface will have 2 colors. The first color is the surface color
and the second color is the color of what it is reflecting. We have
changed the color of the actual surface (High-Res Square) and now we
have to change the color of what is being reflected.

<td class="style12">When

will have 2 colors. The first color is the surface color and the second

color of what is being reflected. By default the reflect node background color is set to black, but we want it to be white. Changing the reflect node background color will give our High-Res square a true mirror effect. The end result below.


You
will also see that there is no shadow in the image below yet the shadow
setting for the light is still on. By adding another primitive prop
between the light source and the ball, we can see that the shadow
option for the light is still on as the second prop casts a shadow on
the ball but not on the reflective high res square.


We
have created some addition renders with different material settings for
the ball so that you can see how different various materials appear in
the reflection.

<tr>
<td class="style12" valign="top">Poser
8 owners have the option to use the Indirect Light setting which can
create a more realistic render provided that the light can bounce off
the High-res square or some other props such as a wall. The thing to
always remember about the Indirect Lighting in Poser 8 is that that it
requires something to bounce off. In the image below we added a blue
single side square as a wall so that the light would bounce off the
wall.




Please visit our lighting tutorials to learn more about the new Indirect Lighting feature in Poser 8.

for some reason you have gone through the entire tutorial and still

material settings should look like this.
