Glass reflections

Anonymous — Thu, 11 May 2023 10:31:06 GMT

I don't know why but I can't seem to get certain angles of my glazing to render properly. They keep reflecting like a mirror or applying full transparency like a window through the model, or something I don't know?

Can anyone explain this?

Notice you can see through the glass in this attachment but not in the next attachment.

Can't see through the glass. OR glass providing window straight through model?

Another user thought this was reflection from the camera light.
Disable camera light ALWAYS!!

Unless you are a miner.

Exactly which glass are you using?

This from the other user.....
Reflection requires something to reflect.
A white background that looks overexposed may not register correctly. Try turning up the ambient light and reducing what ever your main light source is. Or try reducing the overall light settings and this may give you a more forgiving environment to test levels of transparency in.

Post your solution so we can all learn.

@Dwight:

But without Camera light the image is too dark.
Do you mean, it is better basically to switch off the camera light?

This one is without camera light as you mentioned (with realistic sun).
The image is very dark.

This one is with camera light 80%.

The balcony has same material, but shows different color image.
It is too bad.

Thankyou for the replies

Sorry for the delay. I had to go out for the day.

Hi Dwight,

Here is an image with the same settings as other two images and no camera light. This time I used and image background to show that it is not reflection from the window. As you can see in the clearstorey window in the roof you cannot see the underside of the roof. And with the windows in the wall to the left of the image we should see a reflection of the roof again and we don't

If this is so why do the other angles of the renders come out fine?

Here a render with no sun at all.

If you look closely you can see the reflection of the wall to the right of the image. So the material is being recognised.

Sorry Scooter for the broken

@Dwight.
Without Camera light is very nice tip.
Sun light must be ober 130%.
I thought, 100% is the final value.

Camera light off

Realistic Sun 130%

Just from aside, it might be too reflective glass that you're using. Decrease your 'mirror' factor to 0.2 and 'specular' to 0.4 and try again. It will be also easier to diagnose if could post some close-up.

How did you make your nice roof?

Re: Glass reflections

Anonymous — Wed, 06 Sep 2006 14:44:57 GMT

Roof was created in Rhino 3D

Apparently there is a bug in my version of ArchiCAD where Lightworks does not render glass properly so I just found out. There is a patch on the graphisoft website when you check for updates from ArchiCAD.

Thank you all for your input and help.

I have just updated my version of Archicad to the latest version and I am still getting the same rendering problem. Can anyone shed some light on this.

I have attached the latest render example
