[Tutorial]Compositing your render/scene

Post by Soup » Thu Feb 11, 2010 4:40 pm

I've seen some discussion about compositing techniques around the forum and thought I'd make a little tutorial.
The tutorial goes over three methods:
The alpha method - how to make an alpha render and use photoshop to put in a background
Environment maps - what they do
Image Planes - a cheat for getting an easy background and reflections without post-processing.
Enjoy!

Dear all,

I'd like to render an object and composite it in a HDR environment. The problem is, I would like the object to cast shadows on my envmap's flat ground (concrete floor in a business district surrounded by skyscrapers)

In 3DSMax, which i used several years ago, you can define a kind of "Matte/Shadow" material. This is a very special material that is rendered as a semitransparent shadow composited with the background.

For instance, you can do stuff like that:
http://forums.3dtotal.com/attachment.ph ... 1244270455

I don't like the solution that consists in re-modelizing the floor, as this will not connect well with the other parts of the scene.

Regards,

Do you think about something like this

I simply rendered a version with a white floor to get the shadows on "pure" white (tonemapping ist the hkey here!).
Then and cut the Objects out by a separate Alpha pass.

composing back in Photoshop for the final result :)

The image that is used for your objects in the compositing was rendered without floor, right? Then your render on white floor is used only to apply the shadws?

In that case it should work for me. I'll try that!

the method deemed a cheat seems the best way to go for me.. i've tried the other two with mixed results..
this tut gave me the idea of the image plane and it makes a lot of sense.. at the very least, you can actually see how things are going to line up prior to rendering.. everything else is too much guess work..

thanks for the tutorial
