Transparency issues…

[Mark Oertig]

can you maybe upload a small version of the scene?

Hey Mark,

I know this is kinda late….but i still can’t figure this thing out.

I am super confused as to how the refraction, ray depth, and reflection is working with one another.

Attached is my scene file…

Thanks!

in the three Compositing tags on the walls uncheck Seen By Refraction

[Dean Chapman]

Hmm, i try that and this is what i get (ive attached a pic)

On a side note, i accidently uploaded my scene file with “seen by refraction” unchecked for all the planes with the images. So, I made sure to recheck that.

Hi Dean
Like Brian said i switched off the seen by refraction from the 3 wall tags. (seen by transparency on, seen by reflection off) I throwed out all the other Compositing Tags and it looks fine for me. I attatched the file. (R12)
Or should the Walls also be reflected on the floor?
Cheers
Mark

Thanks Mark,

Argh…..when i open your file and simply hit the render button, this is what i get (see attached photos).

I also took a snapshot of my render settings.

Thanks again,

Dean

Hi Dean
hmmm…thats wierd. When i render it, it looks like that (see link).
Rendersettings are the same. (does it eventually work, if you copy all the objects into a new scene?)
Is there maybe a problem with the versionnumber or the system? I’m running R12.048 (Build RC42839) on Windows7 Ultimate 64bit.
Seems to be a Bug. Can someone else confirm that?
Maybe ask Maxon.

Gruss
Mark
