GI Problem
 
So jester you think i should try use a diff light than the spot light

gster123 18-06-2007 11:41 AM

Could do, I think that ther eis one in maya though that cant emitt them, and it could be the spotlight, might be wrong though, give it a go with the area light, jusat convert the spot into an ares (using the dropdown menu in the Attribute editor)

no the spot light is ideal for gi, i think you should delete the light and create a new new and see if you get the same error

gster123 18-06-2007 12:20 PM

Like I said, ive not had a look, but i'm pretty sure that theres a light that doest support GI, might not be the spot, could be the point light or something.

I have tried other lights suprise .... suprise the point light ,area light and directional light does provide mentalray settings . i dont understand so gys if you find a solution to this pls keep me informed

cheers
