I am embarking on a big project which will involve making a lot of custom content but I have a few questions:

1. Is it possible to make a glass staircase for the Sims 3? I know I could just request for some to be made but I rather make it myself so I have it the way I want to.

2. How can I make an object which will diffuse some light? I can't explain this question very well but for example I want signage which will emit light at night or a decorative screen display.

3. Is it possible to make a poster but have different pictures as recolours? Like paintings in Sims 2? Thanks!

1. Yes - HELS has one

2. Try cloning a light that has these properties, otherwise you can try changing the values in the LITE resource.

3. Creating new paintings http://www.modthesims.info/showthread.php?t=377737

Better get HELS then... thanks!
