Some of you may have noticed that I previously posted about what I considered to be insanely high rendering times for the sketch renderer when shadow casting is on. Today I am now officially an ArchiCAD 9 user and I have some good news to report. I tested the sketch rendering speed using the latest version of ArchiCAD 8 against version 9 using the Kohr-I-Noor rendering style in its default configuration.
The image rendered in ArchiCAD 8 took 30 minutes to render while the same image took only 4.5 minutes to render using version 9. That's a 666% speed improvement. I don't know if there is a problem with my installation of version 8 (there is no functional reason to suggest that there is and I've never had an OS X program become corrupted) but this improvement is pretty impressive from my point of view. What are your experiences with ArchiCAD 8 vs. 9 performance-wise?

This rebuild technique doesn't work for me. You must keep in mind that it only renders with extra lines when shadows are on in the sketch renderer (and when you don't rebuild before rendering the same image without shadows after rendering it with shadows). I am almost positive that this is a program bug, because it was like this in version 8 and 8.1 until it was fix in the last or second to last update to version 8.1.
if it doesn't work for you then, yes, it's probably a bug

Bill you must note that I am talking about ArchiCAD 9 not 8. In version 8 it has already been fixed so you are correct. My comment was that it seems to be back in version 9. In ArchiCAD 9 vs 8 the sketch rendering engine w/ shadows is over 600% faster. To me it just wasn't practical to wait hours for sketch renderings w/ shadows in version 8 at such an early phase of a project. With ArchiCAD 9 it is because on larger projects I've seen speed increases over 1000%. For now I just use Photoshop to get rig of them and even thought I've only had ArchiCAD 9 for a week I've already saved many hours of sketch rendering time.
In C4D, look for the light objects, if you see several, look for the sun, click on the sun to open, run the color sliders to white, close and then click on the two grey dots next to the sun object. They should be green. Now try to render.

thanx
It might also bve that the 3ds-file which contains the ArchiCAD sunlight is giving a spotlight on a long distance and with a very small lightcone. Delete it and use a sun/spot of Cinema4D instead.

more possible answers
switch on auto-light in the render preferences - useless for a final render but can be used while you're setting up the scene (especially if you're doing a radiosity render with a sky object with no 'lights') - the auto-light is simply a light placed at the camera position which will illuminate all seen surfaces equally
if you're using a 'sun object' for lighting it defaults to the middle of the night. how dumb is that?. double click it's sun tag and change it to some time during the day!
