bright spots with glossy refraction (the images)

[jacksc02]

Gijs,
Found the problem.
Turn your max depth in your reflection/refraction up to 5 and the spots will dissapear!

interesting thing though, I switched the shader from blinn to phong and the spots re-appear. hmmmmm
will investigate further.

At least it works with the blinn shader! ha ha

ok now this is doing my head in.
The first time I open the file, hit render, i get the splotches. close max, reopen the file, hit render, no splotches. I didnt save the file in between.
I downloaded the file again, opened it, hit render, no splotches.
Weird.

Has anyone else tried this file?

[jacksc02]

Here is my file if someone wants to check it.

No worries gijs,
The file will take a minute to load up. also try right click "save as"

here is an image of what happens with your file on my computer. very strange.

This is gijs file, simply opened and hitting the render button

I als get a different result every rendering. So basically with the second rendering, you are just 'lucky'.

Is the bottom of the bottle coplanar with the floor? does it go away if you increase the Secondary Raytrace Bias?

This appears to be a problem with the V-Ray material; Gijs, you can send me an email and I can get you a fix for this problem.

Best regards,
Vlado
