Point light attenuation

[chris--5]

can someone help me i know how to get the attenuation in spot lights but i dont know how to do it with pointlights if i turn on the drop off it works fine but i have to raise the intensity and what ever is close to the light get washed out can someone help me in softimage xsi they ahve amazing lights i was wondering if anyone knew how i can do this thanks

Create a spot light. Next create an intensity curve for that spot. Then, within the attribute editor, change the type of light from spot to point. You now have an intensity curve for the point light which you can manipulate from within the graph editor.

No kidding!!

That's an awesome tip. Thanks for sharing.

Does anyone know how to use a sphere for example to specify the attenuation region for the light? This will definitely help to visually specify the region.

Are you sure you want to do this? The visual decay regions shown with 'show manipulator' aren't enough?

Or do you mean for a point light, not a spotlight? In that case, you could parent the sphere to the light, then set driven keys for the attenuation and sphere radius...

Try this Mel script available on this site:

http://www.highend3d.com/files/dl.3d?group...amp;file\_id=461

It is in the rendering and shading section for Mel scripts:)

It works in v3 and 4:)

It creates a point light with a sphere of influence of attenuation for you:)

I love it:)
