I'm learning lightwave3d, and I'm almost to the point where I can get my ideas into models. Now I'm trying to tackle the wide world of lighting techniques with lightwave. I made this simple hallway scene but it just doesn't look right to me. I the luminosity on the light up to 150% and I turned the radiosity up to 150% also but it's not comming out clear is there something I'm missing?

Clairify what you mean by not coming out clear.

You should experimaent with cranking the luminosity up. A LOT. If you don't have F-Prime, you should get it, you can play with radiosity and get results in realtime.

you see the clarity it this picture you can see the corners clearly, mine is sort of dark and blurry, Plus you can't even begin to see the ceiling on mine...

If you want a luminous object to be the main light source, it will have to be way beyond 100% luminosity - like 300%, 500%, even higher depending. If you want the ceiling to be lit by bounced light from the hall, you'll need a couple extra bounces & and a lot more rendering time. How about adding a light pointing up instead?

150% Lums for radiosity is kind of low. Your floor is pretty dark in color too. Changing that surface should help with the bounce light.

Thank you guys very much I now understand the relationship between luminosity and radiosity

Now time to try some texturing, does anyone have any tile textures what would resemble a hospital floor. :confused:

Google is your best friend! Whatever you need for 3D, just type it in ~ this one would be 'tiling textures' - better yet, go to a hospital or pharmacy and take some pictures - got digital camera?
