export image > Light map

Hi

I once exported a light map, and it showed up like in the attached image, where lights in the ceiling are visible.

Now I'm trying to do the same, but I can't get the lights to show up anymore.

Does anyone have an idea why?

ps. the lights are made by a emissive material.

Thanks

Hmm, I'm not totally sure what you mean.

Can you post the model/texture that you're trying to import?

Hi Morten

Sorry, my post was very insufficient.

Some time ago I exported the attached image. And now I have to use the same illustration in a higher resolution. But when I export the lights won't show up, and I can't figure out / rember what I did last time :-/

The lights have a emissive texture should they be visible?

Meanwhile I just changed the size of the attached image, not so good resolution, but ok.

I'ii have to experiment, cause it would be nice to know how to export 'lights' next time :-)

Figured it out - the material need to be 'Standard' not color.

If it's set to standard and emissiveness it set it shows up in 'lightning map'

Hmm, that's interesting - I will ask Ferry if it is intentional that the Color material does not show up on the lighting output type.

After investigating the issue further, it seems that a Color material with Overbright set to max will become totally dark if you reduce the Ambient Brightness slider to 0. However, a Standard material with Overbright Emissiveness set to max is not affected adversely by the Ambient Brightness slider.

I will forward this information to Ferry, so that he can check if this is intentional.

I don't have an overbright slider in my standard material. You must have a very special version.

Hi Ferry

Sorry, the two sliders are Overbright and Emissiveness

Point taken, Ferry - which reminds me, why have the Overbright and Emissiveness sliders got different names? From an end-user's point of view, they seem to do the same thing, so it might be worth choosing one of the two in order to simplify things a bit?

@Morten>

You don't have a overbright material in your emissive slider?
How odd. You using the latest version?
