I think I've just about reconstructed the radiosity formula used for San Andreas. It could probably use a slightly higher sun, but that would require more prodding to everything else to get the hue/saturation ratios to match up again. Here's a side-by-side of a quickish solution and some vert colors from SA. Left side is a building in Los Santos, right is the test scene. Top half is viewed from the northeast, bottom from the southwest:



If anyone with Max6 or higher wants to try to tweak it a bit, here's some screens of the relevant rollouts and stuff:

daylight_properties.jpg
sun_color.jpg
exposure_control.jpg

Or if you have Max 8, download the test scene here: http://media.gtanet.com/illspirit/files/MIlightingtest.rar

Note, this is a Daylight system, not Sunlight, and the IES Skylight is default, so no need to muck with the colors there. Ambient light is 0 (skylight entity handles that). All objects should use the default gray Max material while rendering the radiosity solution. At the end, vert colors should be applied as 'lighting only.'

Assigning > Maxscript > More > Assign Vertex Colors

So, yea, if anyone thinks they can get this even closer to R*^'s solution, please say so. Or, if it's close enough, then we could just roll with it...

This is wonderful news. Well done illspirit.
That's this evenings entertainment taken care of.

Edit: The results are great and calculation takes no time at all on a lot by lot basis. If you had to do a lot of them though...

This does seem a little brighter than the old MI-VC standard. I might have notched down the brightness in the exposure control, but if this is the SA standard the so be it.

I like the addition of colour to the lighting, it makes it look like like a really sunny day (as indeed it is here today).

But how can I apply it on my models?

The 3d max reference guide explains about using radiosity and exposure controls.
All you then need to do is assign vertex colours (also explained in the reference guide) and covert to an editable mesh.

So now its time to pre-light the GTI islands properly i gues i will make a start on it soon and give it to Gforce or he is already pre-lighting it. And i gues assigning vertex colors with lighting only should give me better results then i had earlier with my old devkit stuff. Really good work on this one Illspirit it looks promising and almost the same.

Omg woot.
Oh and hay guys.
EDIT: Oh snaps, it's LS lighting, isn't it a bit too, *warm* (color schemes), I'd think MI would go best with SA's Country/SF lighting.

Time to experiment.

ooooh this looks like it could be fun

played with the test scene and it looks like the settings are good to go.

going to do some illcom experimentation next.

thanks for releasing this illy.

Edit: Woohoo it looks like this works fine, time to try this ingame

here's a pretty pic.........

Greate!!!
I'll test it soon on new PC...

[locO G]

Here's a pic of one of my skyscrapers with the new lighting standard.



Radiosity rules!
Of course this does mean I'll have to redesign my shopping centre and create a different standard for all interior geometry (more work, more fun).

Welcome back AleXXX. Isn't it just great to have a new PC.

that just looks really nice and clean that new lighting gives Myriad really an better feeling and atmosphere. all the things really come together this week passed second grade of school and i passed my driver license exam next up is finishing of my drawings for my work and finish of my lots for myriad.



WHOOHO got mine working now too really make my buildings look better but it doesnt looks right now in GTI since whole gti isnt pre-lighted yett my building will look too bright in the surrounding area so im thinking of starting to pre-light all of GTI in the next few weeks. maybe i got 2 weeks of after this week and then i got enough free time to start doing that.

Another pic of the new prelighting.



I have to say it does seem a little on the bright side and tends to bleach out the lighter textures.
I would suggest reducing the brightness a little in the exposure control or am I missing something?
I have double checked all the settings and 'exterior daylight' is checked.
Could there be any difference between Max 6 and 8? I doubt it.
Let's see what happens when others get their lots in game.

First report.
I wait to see what you think, Gforce.

There's no 'warez' here.

Off topic! Off topic!


PS: Has anyone got anything in game yet?

Damn, that's a major improvment! I can't wait to see my lots in radiosity!

@GForce 'tis pretty, apart from some dodgy shading on your Myriad Motorbikes lot

[Black-hawk]

Works nice ingame



and another one from above.



i still need to check the settings but it finnaly works.

[locO G]

I've solved my little brightness problem. It was my fault.

illspirit's MI-PLS workd perfectly, even the road sections match up.

Pre lit locoshops.

That is really looking sweet loco, i wish GTI would look like that hope i can finish of my drawings and then i will start on my lots again.

[Cerbera]

Well done ill, you stuck at it and it looks like all your hard work on matching the lighting has paid off. Even the quick tests on existing lots are looking awesome.

And well done to the folks who've been trying it out and posting screenshots of their results! Black-hawk, that's a top-class piece of architecture you've got there.

You're telling me.
I've had the pleasure of testing it in game and, believe you me, there's a lot more to it than meets the eye.

I'll let Black-hawk explain.

[Jost_Vice]

Damn that looks really very good... I cant wait to see it in action, I need to learn to prelight
All piccies looks sweet
