Rendering a scene:
Make sure that what you see in Perspective view is exactly what
you want to be rendered, then right click on the render icon (
), and
select one of the following:
Monochrome wireframe display:
A simple wireframe render, good for previews. Pretty
much just what you see in the editor.
Wireframe Display:
Same as above, but with colours.
Monochrome Shaded Display:
Greyscale solid render, quite good for quick test renders
of animations.
Shaded Display:
As above, but with colour.
Scanline:
The least processor intensive of the two raytracing modes,
you dont get shadows, refraction and many other things in
this mode. Its excellent for viewing work in progress, and
for some simple scenes it may be all you need.
Raytracing:
This is the best image quality you can get. Each ray of light
is traced from the source, onto the objects, hence the name.
It is MUCH more processor intensive though, and with complicated
scenes you might be tearing your hair out waiting to get anywhere.
Good for final renders.
Render Options window:
General:
Pict.Sequ.
This option is for animation, we'll leave this bit until
later.
Resolution
The size in pixels of the finished render. You can
choose between the standard VGA modes, or pick your
own custom size. 320x240 recommended for test renders,
640x480+ for final images.
Aspect ratio
Lets you determine the higher/flatter ratio
in the picture.
Active object only
click this if you only want the object that is actually
selected to be rendered. Good if you want to check
work in progress clearly without other things getting
in the way.
Path
Where you want to save the render
Object Map
Come to this later :)
Depth map
As above
Format
The image format you want to save the picture in. Iffs are
amiga friendly and interchangeable, but 24 bit IFFS are HUGE!
IFF Comp is a compressed version, taking up slightly less room.
Same with TIFF and TIFF comp. BMPs are awful windows files,
steer clear unless you really need to use your image on a
horrid old machine :) Finally, Jpeg (o),(-), and (+) give
you varying qualitys of JPEG image. (-) being the worst and
(+) being the best. Jpegs are best for space saving.
Wire/Surf.
This page gives you some options on the Wire/surface tracing
modes, most of which are pretty self explanatory.
Raytracing.
Transparency
Choose between none, refractive and non-refractive. Refraction
is 'bending' of light, so if you have textures which use
refraction, you're better having the Refraction on. Otherwise,
with just plain transparent textures, you can turn it off.
If you use no transparent textures at all, you can set it to
none. The result is a quicker render.
Reflection
here you can choose whether reflection is on, off, or whether
the only reflections are from the ground and sky.
Shadow
Turns shadows on
Fresnel
Pass. Wierd german word, I have no idea what this option does :)
Anyone got any ideas?
Voxel, ray depth, Shadow Depth, and thresh value
Usually you can just leave these alone, although
when you become more experienced you might want to
change these to give you a more realistic render.
Smooth/textures/relief/blur/lense effects
Check which of the above you want to be activated. For test
renders you may want to turn textures off, and turn smooth
objects off, which results in a quicker render.
Antialiasing:
This is a very important part of final renders. When you
render an image, you might notice jagged edges and pixelisation
on diagonal lines in the picture. Which isnt exactly the most
attractive thing you can have. Setting the antialiasing value
higher than one makes Cinema4d try to eliminate all these jagged
edges by blending in the colours of these edges with the background.
However, it does make rendering much slower, so dont go overboard here.
You dont need to use antialiasing if all you want to do is
have a quick peek at your work in progress. Otherwise, in a
final render, a value of 3 is quite good.
Below the text field, you can also specify what level
of antialiasing you want. 'Always' tries to smooth
in all of the edges in the picture, 'At texture',
'at edge' and 'at colour change' can be checked or
unchecked to make the quality better, or make the quality
less but the render faster.
Misc:
Picture control of other programs:
You can type a command in this field, and it will
be executed once the render is finished. This might
be good if you want an alarm to tell you when the render
has been completed.
Multitasking
If you turn multitasking off, cinema4d will hog the entire
system to squeeze every bit or processor power from your amiga.
It does result in a slightly faster render, but most likely you
wont be able to abort the render, because this will stop the
mouse pointer from moving.
Disable picture
Will turn the display on the amiga off, which means that the
processor will have less pixels to cope with, resulting
in a little bit free cpu time. Not much, but might be good
if you're going to make a coffee or something and arent interested
in how much progress has been made.
Filter
Lets you add an image processing filter to the final image.
Really just a quick thing to save you having to load the
final pic into Photogenics or whatever, to do it.
Pict. Mode
here you can choose a screenmode for the render. Note that this isnt
the screenmode of the final render, but actually just the mode
of the external screen that displays the render while its being
calculated. Good if you're doing a quick test render, and want
to see whats being drawn while its being rendered, but I wouldnt
recommend it for final renders. You should select 'no display',
which speeds up the calculation considerably.
