experimental vertex color painting lighting engine

Hi,

As an answer to a project's need in the Commercial Work section, I started an experimental lighting engine in Unity.

The original thread : http://forum.unity3d.com/threads/149110-IES-photometric-file-support

The work is still in progress :


Here's a web player demo to play with :

(as a quick start, clic on "L Grid on wall" and "Bake" . You can orbit cam with mouse drag and select lights to edit parameters)

 

WOW dude thats really nice. Amazing job. but isn't there something for this already in unity?.

 

If you're talking about Beast, that doesn't bake to vertex colors, and is only available in the editor, not at runtime.

Yes, absolutely !
Beast is amazing but rendering is very cpu-intensive and takes a long time. And lightmaps textures memory footprint is sometimes also a problem.

Vertex color painting could be a very much cheaper alternative when lighting has to change at runtime (rendering takes only a few seconds depending on lights count) and on a mobile platform (light count is virtually unlimited).

 

Really just need a bake to vert col option for beastie poos.

 

A few experimentations with power and directivity patterns :

 

Wow. Just stumbled onto this for the first time.

Is this happening?

 

We just released a vertex painter that has this feature. It can import beast lightmaps into vertex colors, and can be swapped or modified during runtime. Here's the thread: http://forum.unity3d.com/threads/192711-VPaint-Advanced-Vertex-Painting-Released.
