ArchiCAD 18 - Interior Animation

[Anonymous]

Hello everyone,
I have a problem with my interior animations in ArchiCAD 18 in that the light sources (lamps specifically) seem to be recalculated in a slightly different manner in every scene, thus creating a time lapse/disco light feel to the animation.

Has anyone experienced this and been able to solve it? I have been racking my brain on this for a few days and I would hate to have to ditch the work I've already done and go to Artlantis.

Thank you in advance!

Dear Emmanuel,

The flickering problem will be solved in ARCHICAD 19.

Unfortunately we can't implement the entire feature set of Cinema 4D into ARCHICAD, so if you need the full functionality you have to export the ARCHICAD model to C4D with our export Add-On. This C4D file contains all surfaces/attributes and your rendering settings as well, therefore you can continue work in C4D exactly where you left it off in ARCHICAD.

Exporting the Fly through path is not an option just yet so I have added your report about it to our wishlist.

We plan to update the CineRender Engine in the next ARCHICAD versions to utilize MAXONs new technology.

Best regards,

Hello,

Thanks for your answer.

The flickering problem will be solved in ARCHICAD 19!! It's a very good news, even if I'd preferred a solution in Archicad 18.

"Exporting the Fly through path is not an option just yet so I have added your report about it to our wish list." I do not understand that nobody at Maxon and Graphisoft does it says: "hey, cinerender is not complete, then allow archicad users to export their projects COMPLETELY to cinema 4D, including animations.
This is nonsense.
Once again, thanks for your help.

I'm using AC 19 and having the same problem with moving splotches in an exterior fly through scene. I'm using an hdri and archicads sun. What is the most time efficient solution?

Time efficient, probably turn off Global Illumination or set it very low. Your renders will look dark or cartoony, probably.

Have you tried the suggested settings a few posts up?

The last big flythrough I rendered, I used very low settings to keep render time to about 1-2 minutes max. per frame (1280x720). Result is here: https://youtu.be/5qCM63d4kx4?t=2m47s Most of the lighting is done by a general light with infinite strenght/distance and HDR image.

Be warned though, there is a serious memory leak problem with ArchiCAD/cinerender. Your most efficient way to render is by going in batches of 50 frames or so (for 16GB ram at least), closing ArchiCAD completely to free up memory again and carrying on. Leaving it running for anything more than 200 frames just crashed the OS because it ran out of memory. Couldn't leave it running overnight.

Because of tight deadline I ended up using all available workstations/macbook pros in our office, while basically being limited to 'babysitting' them.
