lighting data

Alex had the question, but it may be useful to others.

Below is the link to a maya script which generates a series of grayscale maps which display the intensity of light on the surface over time.

lightMap script



To use it:

(Assuming you already have the lights animated)

copy the entire script and execute it (ctrl+enter)


First make a material which calculates the light intensity by running from the script editor:

surfLum;


this will make a new lambert with the right connections to it to calculate.

apply this material to the surface you want to calculate for.


The other procedure calculates the lighting over whatever range of frames you specify. The format of it is

calcLight(start frame, end frame)


For example if you wanted to calculate the maps from frame 1 to frame 50:

select the surface
shift select the material

calcLight(1,50);


it saves the maps into your project directory, or if you have hypershade open you can see them all.

paint Example

Hi everyone,

there were a couple of question about "agent painting" last time so I put together a simple example:

paint example


It explains it pretty well in the manual, but basically you need:
a terrain to paint on
a map on the terrain (in this case a blank white image) in tiff format
-the resolution of the image has an effect on how the agent paints as the size is in pixels

To save the map that agents have painted go to File/ Save Terrain Map

Hope to combine with two other agents as macros.

object painting

Nick, I think you told me today that it is possible to make objects paint but which one is the video tutorial for that? I just can find the ones for making objects react to the color but not to make them paint... maybe I misunderstood you? Thanks,

Lara

Performance issues w/ Mac+Bootcamp

Is anyone else having super-slow playback occuring in the viewport on the Macs?
Seems to happen when I load a terrain file...
