Magic carpaint attempt nr2

[Projectkmo]

very good looking so far....but does it change as you move? hehe...

I'm perdy sure Blur has a few Mat/plugins that do that exact thing, or they might help to achieve it......... if you didnt know...

But, for just useing standard max, that looks realy Good!!

oh heres Blur's link to their plugins incase you were interested and didnt already know it

Yep it does!!! It reacts to the possitioning of the light...
Only current problem I'm having now, is that u render it in a GI scene, the effect gets almost fully lost, that's because GI emits light from 'everywhere'.... :surprised :thumbsdow :hmm: :annoyed:

Trying to fix this...

My objective is NOT using any external plugins. It's even the standard type material (not shellac or composite, mostly used, much too slow, with some trickery u can get same effects much faster). I hate using plugins when not nescesary! If it's possible without them, I prefer doing it the hard way! :p :rolleyes: :shrug:

Damn! Having some real troubles with GI scenes, g*dd*mn!!

[CHRiTTeR]

Plz don't mind the 'scene' just a quick 10sec setup to test it...

Very short, low qual. anim (zipped mpg-1 -> 191kb) to see how it reacts to light & rotation ...

[Projectkmo]

wow, looks like you've bout got it!! Looks good...will we be seeing a Mat to dload soon? hehe :applause:

[CHRiTTeR]

Download: Dont know, ... maybe, but don't think so.....
4now this is my preciousssssssssssssssss...........



Sorry, but u understand... ;) (but there is a tiny chance I'll do it)

[Projectkmo]

tease!!!

though, I doubt I'll be modeling any Gheto cars or Old School Bass boats anytime soon.....so I suppose I can live without the morphing paint.

[Slater]

sweeet!!
it reminds me of a toy car i had when i was little...you know those ones that change color if you put it in hot water!!

hehe nice renders.

Hot weels !!! I had those too :)

Nice work Chritter:thumbsup:

I asume that the effect is done with a light effected falloff so thats why it'll be turning to custard in GI ( I suspect you know this anyway).
So why dont you just do it as a composite shot.?

Render out the colour pass, Reflections or/and specular pass, then finally the GI Hadow pass.

That way you could controll the colour chancge and still have all the GI settings. Also this may give you more control as you can the move the light to change the colour as you see fit.

I may be way off track here, but it may help. I suspect you may reply that you want to do it all in max, but dont be affraid of a lil compositing ;)

Good luck.:bounce:

Wow :eek: , we've got ourselves someone telepathic abilities over here! :eek:


So, ... yep, I want it all in MAX.... I'll find something, ... I hope ;) :p


PS: It's not a fallof-map ;)

[Chico]

:p :p :p :p

Well Id be interested in finding out a lil about how you've done it then at some point, when you are feeling generous ;)

[CHRiTTeR]

Isn't there a way to set the value of how much GI the material receives in MAX5???

Like in Brazil, Vray, FinalRender ...


:hmm: :annoyed: :shrug:

[-wT-]

Hey, a small tip to make your GI images look normal:
Remember that GI is usually used to simulate outdoor lighting? Well, you know, apart from the sky itself, there's the sun ;)

[CHRiTTeR]

I know, ... it still looks f*ck'd-up

[-wT-]

Oh?
Hm... Would've thought a simple directional light would make it look good... Oh well :)

[CHRiTTeR]

Yes, that's what i used in those examples I posted here, but for in case I would like to use it in a GI scene ... :rolleyes:

[Chico]

I still think you should comp it.

You will gain nothing out of doing it all in Max, except maybe satisfiying yourself ;)

If you do the GI then comp the colour you should be fine. IMRO

Yeah I know, but even it's harder, I'd like to do it all in one step. If I find no solution, I'll do it in comp. But I haven't ANY experience in comp...

[Chico]

OKay, Ill see if this helps you out.
It's just a basic form of compositing, but it should be enough to get you off to a good start. All you need is Pshop, or any composite package for doing an animated sequence.


Generate Colour Pass:

Turn off GI. Just use scanline for this one.
Note that if you only had skylight you'll need to also add new lights for this.
Turn off shadows in the render options.

Set up you material as you see fit ( I set mine to 100% self Illum, but I doubt that will work in your case)
Render


Generate Shadow pass:

Enable GI. (you may want to change the lights set up for this pass)
Apply a Shadow/Matte Material to it, make sure its set to "Recieve Shadows" and set to "Affect Alpha"
Render


Basic Composite:

Take each pass into photoshop, and play with the blending modes.
In this case all I did was put the GI pass ontop with blending set to "Multiply"


Other notes:

Simple enought to also put on a "raytraced" spotlight rendered from the scanline with this technique.
now you can change the colour pass to whatever you like and not have to re-render the shadow pass.
I used mainly screengrabs to quickly put tthis together, normally you just use alpha channels.

I hope this helps you out a little. Or at least gives you an idea.

[CHRiTTeR]

Thanks very helpfull!!! :beer:

I know photoshop very well, but I didn't know how to render those different passes.

And when I sayd I don't know comp., that's because I thought u ment doing it in Aftereffects or combustion, which I have totaly no experience with.


Again, thank you very much !!!!!
I'll try it out soon, but my machine is rendering some stuff out right now..... :surprised

[Notum]

another way would be to go into "properties" for the object that you don't want to recieve GI and turn it of in the "advanced lightning" tab.

at least I think that's possible... if my memory serves me right... can't check at the moment.

[CHRiTTeR]

Yep, that possible. Well kinda...

It gives u the possibilty to exclude the object from the advanced lighting calculations. So, it also disables that the object casts Skylight shadows... This looks very 'fake' and the object isn't well integrated in the scene anymore...:hmm:

Brazil, Finalrender and VRay have the ability to set a percentage of how the material should receive GI, but max lacks this option... :shrug:
