I have an assignement for my class where i have to light the same scene three times...

- Morning
- Night
- Mood set up (get an idea of a mood in the scene)

I decided to model a chatedral and try and light it.. but little did i know that this is gonna be a difficult thing for someone that just started to use maya 4 weeks ago.. haha..

The modeling is soposed to be kept simple, the proffesor doesn't care about the modeling part yet, they haven't tought us much yet.. but he wants us to work on light setup..

I guess i'm looking for suggestions on where to place my lights, what colors, and how many...

this are the lights that i placed in my scene.. the main light source is missing, thats gonna be the sun, coming in through the big round window at the front.. thast gonna be that colored glass that they have in chirches...

This is what my scene looks right now... with two big sport lights coming throught the windows at eather side.. then a area light to simulate the light reflection (radiosity) and two pint lights to light up the little passage ways behing the columns..
The way i see it now, it doesn't look right... But i can't put my finger on what i did wrong.. Maybe just using one light for all the windows isn't the right thing to do.. should i have a separate light on each window?? what kind of light should i use there??

should i maybe keep the main light, and then give each window a point light???

haha, thats actualy the only site that help me out a bit, I found that last night...


But i have a little problem... I have my main light source (the sun) and it casts a shadow as it enters the chatedral... The problem comes when i have to simulate the light bouncing off the walls.. coz they have to be outside of the walls and i have exclude my structure (the walls of the chatedral) from casting shadows, but when i do this the sun wont cast a sharow anymore... is there a way of seting up lights so that certain objects dont cast a shadow..


i know of the option where you can set the object not to cast shadow, but that turns off shadow for all the lights...

Well. Man you're screwed. Just kidding. Only four weeks of maya and that's your assignment. What school are you going to.
Anyways here's the best tip I got from my teacher on lighting. Base your light off a photograph as a starting point. SoI would suggest Find a pictures that best matches your church and base is off that. If you're trying to just make up the lighting you'll spend for ever tweaking and never get the right look. Just cause you don't really no where you want to end up. Make sure that you're reference pic has a very strong source of keylight that way you never loose sight of your main lights. And what ever you do don't use ambient lights you'll never be able to go back to full darkness unless you delete them or turned them off.
-Also unless you're trying to simulate the sun or moon your light should have decay rate truned on.
-Try to use spotlight they allow you the most control. Hope it helps. I know its not much. But hey what the hell. Oh yeah you can fing amazing ref. at greatbuilding.com

you should EXCLUDE the walls from casting shadow JUST for the bouncing wall lights. it should be in LIGHT properties. do NOT turn off the object casting shadow. (i don't know excactly where in maya it is, but in max it's in light parameters roll down, ask in Maya forum)

It's a good idea to render off separate passes for EVERYTHING. So for each light do a shadow, diffuse and specular pass. Then put it all together in Photoshop and tweak until it looks right.
