View Full Version : Problem with glass shader

05 May 2009, 01:30 AM
Hi Ive been trying to create a decent glass bulb shader and for some reason on two of my bulbs the glass is a solid blue color. Would anyone know why. FYI raytracing settings are up and normals are bot reversed.

this could be your background color

By background do you mean sky? I thought this too, but I'm not quite sure why there's such a strong reflection when I'm looking straight on. I have the 0 degree option in the mia_material turned down.

why dont u try to add a blinn with the transparency set high and give the transparency a color....
also turn down the color see if it works
if u are using mia material....start off simple with a simple mia material and increase its transparency and hide everything else in the scene...
if it still reflects the sky color try adding a relector...a simple plane with a surface shader set to white or the color u want to reflect and dont let it cast or recieve shadows and also hide its visiblity

the image shows that it might be the roof,maybe its visible in transparency or refraction is off just put an object behind that wall and if the blue spot is gone you have to deal with top of the room......Goodluck

Thanks for the replies. My teacher just showed me that in the render stats of the light bulbs they were unchecked for visible in reflections and refractions.

Yes, remember that all object you import in to maya, outside from maya, you check on visible on reflection & refraction, and if you have more object, use the attribute spread shift.
