Odd Glass problem

[mdi]

Hi All,

never had this before, and im sure im missing something obvious but what??


Problem is this...

cannot get light though a simple box/glass shape.

see left and right of image...

What if you check the "Affect shadows" option for the glass?

Best regards,

no change

[nvanherpt]

what happens if you set your diffuse to white?

[mdi]

no change..

I even rebuild the window glass with a new object, and the problems still there

[mdi]

ok....i think it might be a scale problem or somthing...see attached...


once I move the window outside of the wall eveything seems to work ok..any ideas?

[vlado]

In the V-Ray indirect illumination settings, do you have "Refractive GI caustics" on?

Well, I'm all out of ideas then; if you wish you can send me just that part of your scene to vlado@chaosgroup.com and I will be able to tell you more about why this happens.

woot....figured it out..

It was todo with the vray sun, I deleted it and put a new one in the scene and it all working now!


Very strange though

[mdi]

nope...forget that last post...ill email over the scene to you vlado

Just to clarify you need both refractive GI caustics AND affect shadow on for it to work.

You may have missed the right combo for it to work.

i fixed it, not sure what the problem was...im sure it was all my own doing though, clicking this, clicking that.

Anyway, I merged it into a new scene, and copyed a few settings and it seems to be working now

[nvanherpt]

be good if you can figure out what fixed it. i've got the same issue now...

oh...

All i did was to merge it into an older scene that was aready setup and working...then made sure my windows had the same settings (object/vray properties ) and bobs youre uncle it all worked.

But i dont really know if the problem was the object properties or the render settings....sorry
