From what I got from some of the lbp2 footage, It looks like there is an actual light particle system. I.e. an emitter that is specialized in emitting light for special effects like those light trails you see in one of the trailers. 1. Can someone confirm that there is a light particle system. and if so: 2. Why the bleep is nobody hyped about this. A light particle system can really weally improve a lot of visuals, effects and even gameplay elements, even create new gameplay elements that could not have been thought of without such a system. For instance, you could create lighting without the use of solid objects and logic, or create your own fire or even alien laser effect. On that note, what new changes have lights had, what has changed what is new and what is improved. Is there finally an invissible light source? (The one you have in lbp1 has to be obtained trough "glitching" (stealing it from MM official object).

From what I got from some of the lbp2 footage, It looks like there is an actual light particle system. Not sure what you are referring to, but For instance, you could create lighting without the use of solid objects and logic, You can use the holographic material for that. It has physical properties and when set to the default off colour it's invisible. So for lightening you can just randomly turn on and off a number of flashes made out of that material. what new changes have lights had Well, they have a off colour and there are more shades to choose from. That's the only thing I can think of, at the moment. Jack probably knows more about this.

There is a fogginess setting with a percentage in LBP2 if that's what you're referring to.. (The part of the trailer where light appears to be shining through a hole in a cave)

I think he's talking about at 1:18 in the video. http://www.youtube.com/watch?v=Fs0T5l24JL0&feature=player_embedded

It looks like a bunch of LED's hooked up to some type of rig to make that effect. Not really sure what you're talking about though. :x

You mean the vacuum material?

its between 1:18 and 1:20 if that is not a particle light system, im eating my ps3 controller. Thats no vacuum nor the holographic, it looks too much like a lightparticle system ive used in some prev. editors from other games. Even if its just fog-fallof from the light, that would be considered a particle effect. (in most editors) Its strange that nobody is really hyped about that, take it from luos.. a (light) particle system is much win!

1Thats no vacuum nor the holographic, it looks too much like a lightparticle system ive used in some prev. editors from other games. Even if its just fog-fallof from the light, that would be considered a particle effect. (in most editors) Right, I now think I understand what you're getting at. Like at the moment, if you move a light you just have a single source that moves. Here, we're seeing residual particles being left behind and quickly fading (the fog-falloff)? I don't think it's something we have much control over in the new game, but I think it's a standard part of the updated lighting. Fire and things look a bit like they might be created using something like this as well, though I really don't know, as I'm not exactly clued in on this stuff. Have you looked through all of DonkeyShow's e3 vids, there might be some more evidence there - in the gamejam levels anpostteller and steve_big_guns used a lot of fire. Can you tell if that's the same kind of effect Its strange that nobody is really hyped about that, take it from luos.. a (light) particle system is much win! I think most of us are going with "**** that looks pretty", with the new lighting, rather than understanding exactly why it looks so pretty

He seems to explain something about it here: http://www.youtube.com/watch?v=afjZUFRNLqc Starting around about 0:50 i can hear something something "particle" but I am not sure, and the mind often wants to hear what he wants to hear. (especially in my case ) but in this movie, (at 1:30) it just seems like a lot of lights attached to eachother. http://www.youtube.com/watch?v=YZa0LHHb6Ho __ In this movie: http://www.youtube.com/watch?v=5KaG6HIDyIc at: 7:28, the blue lights going, the way the light on them moves also feels like particles. Yes the flames are also particles, but looking at the way the worked in lbp1, they just enhanced the visuals on that.. (and boy did they do good!) it does seem like the fire has its own light, but could just be hiding some lights behind a layer or so __ What I did notice is that some of the movies do show light with falloff or "tracing", I think the 3d shooter just uses lights on i.e. invissi strings or so to make it look like a trail. Gas, explosions, picking up scorebubbles, fires etc all used particles in lbp1 as well (particles is nothing more than emitting transparant images (in lbp's case that could be transparant stickers) in a either calculated way like the lbp flames, or more controlled trough a setup of a few images that are emitted semi-random to create the illusion of i.e. real flames. At least, thats how they did it in most editors I have used in the past. What syroc said might be the way to do it though, but its just a speculation. You can use the holographic material for that. It has physical properties and when set to the default off colour it's invisible. So for lightening you can just randomly turn on and off a number of flashes made out of that material.In that case, if you have an image that looks like a lensflare or other transparant like light, and you emit them through these holographic materials.. you could make some insane trails.. but afaik... they wont have light propperties.. But on the announcement vid at 1:18 - 1:20 it really does look like a light-fall-of like particle system. I guess we just have to wait and see

i can hear something something "particle" but I am not sure, and the mind often wants to hear what he wants to hear. (especially in my case ) He says 'thats the power of the holographic material.' I too don't really know what you mean about the whole 'particle' thing. But I can say that it's definitely not something that's an actual 'feature', as in it isn't something that the player has direct control over. Like Rtm said, I'd say it's more to do with the overall improvements of the lighting.

I asked about this while I was there. The announcement vid at 1:18 - 1:20 is just LEDs behind the material. A motion sensor just triggers the chain of leds. Its the new engine that makes it look so good.

Its the new engine that makes it look so good. That was actually my first thought after I seen what Luos was referring to in the video, but with all the technical stuff being spouted I thought it would be silly to mention such a low budget way haha Anyway, so yeah, it is just the overall lighting improvements that make it, not a direct feature.

aww too bad, would have been awesome to make your own flames, lights, lightning bolts etc. But, you prolly still can with the holo mat.

Check out Rtm, Wex and Comphy's level to see how the holographic material can make electric cable stuff...that's awesome.

Yeah, with the holographic material you could do a frame by frame animation of anything, lightning fire etc and then hook that up to a switch (forget its official name) that just cycles quickly through each "frame" of the animation. It wouldn't give the same effect as what your looking at it the vid but would certainly give a nice effect. Just seen Jacks post and he reminded me that I actually done just that Check out at 5.10. All I done was make some lightning shapes of holo and hook it up to a randomiser and a timer switch. http://www.youtube.com/watch?v=5KaG6HIDyIc&feature=player_embedded

Check out some of the written interviews with Alex Evans, I think he talked about lighting and the new engine in some of the earlier ones. One of the improvements of the new engine is that every light now casts shadows, as demonstrated by the light rays in the fog. As I understand it, it won't cast very sharp shadows, though.

There is an interview with Alex Evans were he says that his favorite feature in LBP2 is the sprite light and how it gives a nice effect. Now I'm not sure if that's what ur talking about but I just have one question: What is a Sprite Light? I tried searching it on Google but this is what mainly comes up: http://farm4.static.flickr.com/3603/3610721745_ce0efa240f.jpg

From what I get from you guys (wex mostly), the holo material is some kind of surrogate/lbp-kind of version of particle emitters. I could work with that. A friend of mine who created comics would like to know if you would be able to make like a holo-materialized semi-interactive comic. Would anybody be so kind to give a decent speculation?

the holo material is some kind of surrogate/lbp-kind of version of particle emitters. I don't think so, but then I'm still unsure exactly on the technical terminology of the particle systems and what exactly counts. Suffice to say that the holograph material has some really interesting visual properties, including the variable translucency (switch controlled and sticker modified) and I'm sure someone like yourself will find plenty of use for it. Not to mention the fact that if there was stuff in the video that looked like light-particle systems, then surely that means there is plenty of scope for faking similar effects? As for your friend's question - I don't see why not... Depends exactly what you'd want to do.

Depends exactly what you'd want to do. If I can fake it, I can probably get it just the way I want to.. I hope. It varies though from creating ghost like figures that are visually more appealing than just a blob of gas to massive storms of lightning, fire and wind and anything in between. I cant give excact details on what he wants to do with the comics, but if id push you in a certain theme, it would be a bit like this: http://www.youtube.com/watch?v=azIZwsCGjW0 http://www.youtube.com/watch?v=azIZwsCGjW0 The oh so awesome genesys game "Comic Zone".
