Those pesky little light symbols...

[turner]

Hi all,

First post, noob q.

I'm seeing little symbols where my point lights are, though the image is rendering correctly.

Did I accidentally activate some type of visibility or something? I can't figure out how to get these to go away. Today is the first time I've seen them.

Thanks!

Point lights can often leave a bright spot where they are located, it happens because the area around the light point is very bright, and pixel filter spreads it out a little. It's very evident when you have scattering turned on:

LuxBlend25 does have a new option in 0.9 to use a sphere primitive instead of an actual point light (the "use sphere") checkbox, so you can check if that is disabled. All in all though, point lights usually don't give very good results, they don't represent any light source you'd actually find in the real world. Some kind of area light (mesh light, etc) is almost always preferable.

Thanks Jason. Thanks for the quick reply!

I'm using IES lights, and from what I've read, point lights are required for correct IES rendering... ?

cheers

By the way - here's a screen grab showing the spots. They don't look like what you're showing though.

I seem to remember that changing the filter that you use can fix this...

Or was it that it didn't, I can't remember. Anyway, try it, it might work.

Yup, they are errors introduced by the Mitchell filter, just switch to another kind of filter.

Hi guys-

No luck.

"Box" seems to work the best, but still shows a tiny point. All others look pretty much like Mitchell, at least as far as showing a white blob goes...

I'm rendering right out of Blender, if that matters.

Thanks again!

You can easily remove these bright pixels in postprocessing with Gimp or any other graphics editor, no?

Depends on the background. I'd rather not have to.

But are we talking of the black halo caused by the Mitchell filter or of the fact light sources are visible
