CineRender light problem ("spots", "clouds")

[Anonymous]

Hey everyone - I'm testing CineRender and I see this problem with light - there are light "spots" or "clouds" that appear on the walls. They change on each frame if you do a fly-through. My guess is this is some form of render issue and can be avoided with proper detailed settings in CineRender - does anyone know how to get rid of these? Thanks!

Am I the only one who has this problem?

http://archicad-talk.graphisoft.com/viewtopic.php?t=47435 I think this discusses the same issue.

Thank you, Erwin!
It does sound like the problem I have.
But the proposed solution is absolutely unacceptable since these settings send the rendering time in ranges of weeks, when we talk about a fly-through.
Is there a more reasonable solution?

Hi Vic,

all the issues that you're having are resolved in my tutorial here:

basically you have to apply GI (Global illumination) in addition to cast more lighting using Area Light and last but not least you have to apply Physical Camera to let the lens catch more light and camera shutter close at proper timing ...

have a look at the tutorial and you'll be more than happy with the results that you're going to achieve

Muaz - your tutorials are fantastically detailed! Thank you so much for making them - you really explain a lot.
While you offer a very good solution for the "clouds", I still think this is a workaround, solving an issue that is a result of bad algorithms.
Let's face it - these "clouds" make no sense, they are absurd - the surfaces should be evenly lit, regardless of how weak the light and illumination is.
Once again thank you!

In my opinion the problem has more to do with the type of shader that Archicad still uses. Shaders consist of "patches" of a certain size. The smaller these patches the less problems but if the patch contains textures then also the quality suffers. Same problem you see in interiors where walls and/or roofs meet. Like a bit of light shines through.....
