...Variations of Illumination >>> Lumion 9...

These are tests with variations of lighting settings in Lumion 9. The render time was approximately 11 seconds using a 1080i GTX
In the last image you can see the importance of the "HiLight" feature when using only one texture to simulate the internal lighting of the house.
Hope you like it.

Wow! These are very good! I never use this kind of interior lights. I asume it's just an illuminated texture?

Yes, it's just a "Tiff" texture with alpha channel

Hi Gilson, these are excellent !

I'm not sure to understand the HiLight process, could you please develop a bit  ? How do you use the TIFF texture and what settings do you apply to it ?

I'm always struggling for hours with light sources to try to obtain this...

Thanks in advance and keep on rocking !

That looks great Gilson!

As for the TIF texture, Did you just create a second plane to sit behind the glass that then has the texture applied with the emissiveness turned up? or does the TIF file you're using contain actual lightmap information?

This is the route I'm going for a rather large city scene, I've created a couple of interior shots taken from directly in front of the window and then cropped these to the size of the window to essentially "bake" the interior to an image that I can then adjust to create several variants too be scattered throughout the buildings windows.

Well done!

Hi Adam and Seb, please take a look at this article to see how to make some parts of a material more emissive:

Ah yep, I have had a brief play with that feature but nothing too complicated. I take it that's what Gilson is referring too then?

It would be interesting to know if Lumion registered this the same way it does Glossiness/reflective information in the Normal alpha channel, where by varying shades of darkness would indicated the strength of emisiveness. Is this possible? or does it only register a flat mask?

Hi Adam, this is explained in the article above.

Here is a quote:

"A pure black color will not be emissive at all in Lumion and a pure white colour will be fully emissive. Grayscale tones will be more or less emissive depending on how close they are to pure black and pure white."

Does this make sense?

Thank you!

AdamAV, what I did was simpler, I used the very plan that would be the glass to apply the texture with emissivity, see a quick tutorial.

No need for a Glass Material on those windows when they are fully textured. Nice one Gilson.  :)
