Lighting Challenge: Light Bulb

#41

Give us one then.

#42

whippersnapper.

#43

I’ve heard this NPR thing tossed around here for long now and still don’t know what it is :shrug: Someone enlighten me? Pleeeeease?

#44 
NPR = non-photorealistic rendering :)

I found a nice quote in one book that deals with NPR: "Photorealism, like pornography, leaves nothing to the imagination."

So David, we are eagerly waiting for your NPR version of the light bulb… :eek:

Rendertime 20sec. :wink:
btw: how did I get myself into this?

#46

Thanks! Yes, well, David should then show us how it’s done, I suppose. This PR attempt of mine has frizzled me out and I need some NPR eye candy to relax again. And while you’re at it, try for something with a 5min render time. I’m still shell shocked after that 18.5h render. :slight_smile:

#47

David, that is looking very cool!

My favorite so far on this thread :wink: :thumbsup:

May we ask for a shadertree or some hints at least?

Cheers!

#48

OK, now that’s a respectable render time. Keep 'em coming, you’re starting to warm up :thumbsup:

#49

:-/ I wish this were done in messiah, I rendered in LW, using a sub-frame displacement synched to motion-blur AA passes. And one area light - ambient at 20% deep blue. I worked the technique out for my short film “Love.Leech.Tomato” - on which I’m progressing…
I’d tried to get this going in messiah, but ran into problems (ie sub-frame keys). Thomas, your post a while back had me thinking this might be dobale after all, but I couldn’t get those results. I would LOVE to cut LW out of the pipeline - matching cameras and all that - but… can’t get this to function.

@Paul - I am warming up! But mostly with rig / animation stuff. I’m discovering again. And have time to do so. What a feeling!

#50

Yeah, you can’t do sub-frame-key-repeats in messiah, but when I need that, I normally set up an expression. What kind of keyframing do you need? Maybe I can help out?

Fine displacement with some fast animated AoN shaders should at least give you something similar?

If you repeat the same displacement-animation per frame, you should even be able to get rid of the flickering, or most of it…

Cheers!

#51

If you’re serious, I’ll send you a scene. Another problem is that I control the amount with weight maps. I can get around this by hooking up metaeffectors though. me thinks…

Well, ideally, I could set it to a slider so that I could go from no jitter to freaky wild :wink:

#52

Yes, either metaeffectors and the weight shader multiplied with your strength, or you create an uv map and paint the weights on in ZBrush as a texture or something similar.
I personally don’t like metaeffectors.
I wonder if we ever will see weightmaps in messiah?

I never tried that, but with the same displacement animation repeating on each frame, you should get the same pattern for each frame = no flickering. The more you make this discontinuous from frame to frame, the more flicker you will get. Should be easy to bind that amount to a slider…

I still don’t fully understand what you are doing but I guess it should be doable in messiah too…

Is the noise post?

But the thing messiah is missing is an edges shader - I guess you use one in that rendering?

Cheers,

#53

No post on that one. I did set this one to get an alpha, and adjusted the metal / glass with it. Remodeled a bit to get more of the look across in the geometry.

Hey, you wanted xsi, right? Wanna barter :wink:

#54

hehehe - sure thing - “barter” sounds good if I understand it correctly :slight_smile:
I could even put a TLHPro License on top of that deal :thumbsup:

Maybe it is best if you send me that LW scene so I can see if I am able to reproduce it for you in messiah.

“barter” - learned something new today :wink:

Cheers,

#55

Looking good David! Is this still LW?

#56

@Paul - yeah, LW. Thomas isn’t THAT quick :wink:

#57

Careful - I’m already finished :wink:

Cheers,

#58

how the hell do you get 18 hour renders? lol, i have an FX-60 cpu and it renders in 12 minutes but its not exactly a rocket ship by todays standards… although the AA could be better i admit.

#59

GI was used, and add to that a sphere light casting a softshadow at AA level 4, and obviously all the glass reflecting and refracting the GI and the soft shadows… this on a 2.8GHz P4.

#60

I need some help guys. I started to do some render tests on the bulb for our challenge in Messiah but I can’t seem to get the shadows right. In this render I have a sphere light casting raytraced shadows with a quality of 5 and a spot light with the same shadow setting there is no shadow in the render.

When I switch the sphere light to shadowmaps the quality of the shadow looks like crap. I need some guidance with my shadow settings if you guys don’t mind helping me out. :slight_smile:
