V-ray invisible object reflection
-
Hi guys,
Thank you for you answers but I forgot to precise I did not apply any vray material on these windows. The glass is the "grey tanslucent glass" from sketchup. I like the blue reflection it makes, and don't want to use a vray glass.
WHAT THE HELL IS THIS REFLECTED SPHERE ?
As you can see in attachment, I made a whole facade with a copy of the window, and the sphere appears. Whatever if I zoom in or zoom out, the sphere keeps the same size on the image.
Also, but that' not the main problem, why can I see two shades of blue-sky reflection for a same material ? One is really blue, and the other one looks less saturated.
Thanks for the help !

try disabling "caustics" in your vray options.
worst comes to worst, upload your scene so someone can take a look at the file itself.

I don't know anything about Vray, but is it possible that it is a sky dome or something like that. In twilight for example, setting a hemispherical sky will give a very different result to a spherical sky and sometimes that results in a blackhole like you are seeing.

Change you Face Style to Monochrome and then post an image of your sketchup model. As ThomThom alluded to it could be that you have the Translucent Grey Glass material applied to the back (purple) face of the window which when rendering causes all sorts of weird things to happen. The reason I'm suggesting that this might be the problem is because I see that you have other faces that should be reversed (aka all purple faces should be reversed).
And as a second note, default Sketchup Translucent Glass Grey wouldn't have any reflection properties as Sketchup doesn't do reflection. So in order to have reflection it would have to be turned into a "Vray Glass" material so to speak.

rspierenburg is right. Default sketchup material will not have reflection unless you add it in the vray properties. That's why I'm guessing you also have a refraction layer. Is your glass a single plane?

without a scene file, it's impossible to tell

This takes the award for craziest thing I have seen.

A little off topic but..ok.

How did you not get that joke???

What joke?

aww. Matt, I understood the joke - the problem render looks like the big rolling stone IJ runs away from...

I think I may have a solution. Don't mess with the transparency in the refraction layer, unless you have more than one refraction layer. Just leave it black
