View Full Version : How can I make a luminous poly that actually casts light?

I've searched for "luminous polygon lightwave" and all I get are people using other packages talking about how they do it and how Lightwave can't. :bangwall: But I think it can be done in Lightwave. I just don't know how.

It's easy to make a polygon luminous in the surface window, and that makes it stand out in renders, but it doesn't actually cast light or illuminate other objects.

Maybe it's an obvious step I'm overlooking. How can I do it?

Thanks!

It will work if you activate global illumination in the render options. Then light cast by luminous objects is taken into account.

in general set luminosity to 100% + and diffuse to zero.

Then use a global intensity - not backdrop only - lighting scheme.

check the manual to find out more info as it applies to your situation.

Good deal, I turned on radiosity and it did illuminate another object slightly. I found this amazing picture in the 9.2 gallery http://www.newtek.com/forums/showthread.php?t=64176 and I'm amazed at how bright it is, when the creator said the luminous poly is the only light source. I cranked the luminosity up to 100% (won't go any higher) and only got a fraction of this light.

I'll RTFM :)

Thanks for the help!

You can go above 100% but you need to type the number you want. Don't be afraid to try some very large values to see what happens. That applies to many other lightwave settings also, such as many suface settings.

Holy crap, you're right. That's what I get for being a conformist.

Thanks!

LW has been able to do this for years. Im curious as to who was saying that LW cant do this.

So WARANGEL -

the light dawns eh?

sorry - couldn't resist.

Indeed. And there's so much more I need to learn but I don't see covered in the manual too. I need a book or some good tutorials. I need to get smart with modeling as well as render techniques. In playing with dynamics you can scroll the fields way past 100 in most cases, so I just figured that if it stopped, that was it.

Yeah, seems like everywhere you go on the net there are people that feel like their program is so easy while getting Lightwave to do the simplest things is akin to working on strands of DNA with the naked eye.

Looking forward to getting more involved with this program.

Speaking from personal experience? :ohmy:

My experience has usually been the opposite. :)

It works perfectly in Lightwave, its simple to set up. Control the luminosity on a poly anywhere past 0 and depending on the radiosity percentage amount, you get some really nice lighting effects. I sometimes use luminosity textures on dome geometry for some nice effects.

Its actually about a four click process in LightWave to get lumionous poly's to get them casting light. It sounds like ignorance on behalf of users who use other packages and say that about LightWave.

I've had the privilage to work with scientist working on DNA, while I work on content for them. I can definately verify that getting the content built for the DNA scientist and getting luminous polys to cast light was definately easier than their particualr tasks.

What was interesting was that there was another chap working on the team using another package that is much more "talked about" and touted as the bees knees.

What was interesting was he never could get anything completed in time for our projects. I always did, pehaps it was just my bad Karma putting him off.

Maybe somebody using another package who takes longer and charges more to do the same thing, thats just a hypothesis of course.

Jeepers, Graham - just noticed your "Location" ... back in the Emerald Isle? Don't you owe me a beer? Man, you're really going to make me work for it, aren't you! ;)

Sounds like it. I guess some ppl assume that if its a pain in the arse in their 'high end' app that its got to be more difficult in another. Check out this thread for example: http://www.spinquad.com/forums/showthread.php?t=18903

I think the last time I saw you was in Vegas, at dinner with Molly and Dick.

I'll buy you a Newcastle brown, not that New World rubbish :D

Thanks for providing that link, most useful and insightful. :thumbsup:
