3D Video Rendering is slow

Hi everyone,

my wife and i are looking for a used house so we use sweet home 3d a lot to show the construction plans of interesting houses in 3d and set them up. Makes it much easier to imagine the remodeling possibilities.

Now, however, my PC needs a good 2h for a 3D tour on the fastest rendering level in HD. Also, SH3D seems to be using my PC at almost no capacity. (See screenshot, only one of the 16 cores is used).
In older forum posts I have read that SH3D fully utilizes their PCs. (But there they where talking about old DualCores).

Anyway, can I activate multithreading somewhere?

Thank you all smile

Re: 3D Video Rendering is slow

Hi Peterschnecke,
das ist ein merkwürdiges Problem. Konstest Du es schon lösen?
Falls nicht, wenn Du die 32 Bit Version nutzt, dann versuche mal die 64 Bit Version von SH3d. Evtl. hilft das.
Ich denkke das Multithreading kann man weder ab- noch anschalten. Einzige Möglichkeit einen Kern nicht zu nutzen wäre im Tastmanager bei den Details und dort mit der rechten Maustaste auf den Dienst /Programm klicken und per Zugehörigkeit eizelne Kerne ausschließen. Aber nach jedem Programmstart wird das wieder zurückgesetzt... also eher unwarscheinlich.

Ich habe den gleichen Prozessor in einem MSI X470 gaming plus und da läuft die 64 Bit Variante unter WIN10 nicht korrekt. Ich kann keine Möbel importieren, sie werden nicht angezeigt. Die 32 Bit Variante läuft bisher problemlos.

Allerdings ist es bei mir so, daß trotz der 100 % Auslastung aller 16 Threads und alle Lüfter auf Maximum, das Rendern eines kurzen 16 Sekunden Test-Filmchens mit 426x240 Pixel und 402 Bildern stolze 55 Minuten dauert.
Eigentlich wollte ich ein 40 Sekunden Film mit 1920x1080 bei 30 fps rendern lassen, ab da orakelt SH3D mehr als 5 Tage Rechenzeit...

Da Du mit nem Ryzen ebenfalls Probleme hast, hoffe ich nicht, daß es am Prozessor liegt...

Grüße
Horst

Re: 3D Video Rendering is slow

SH3D uses all cores when rendering in quality setting 3 or 4, not when in setting 1 or 2.
Although using all cores gives more computing power, this is made obsolete by the far greater amount of info to be computed.

Render time is influenced by:
- make invisible what is not seen in the photo/video (models, levels)
- use small models instead of large models (1 MB coffee maker vs 10 MB coffe maker)
- use small textures instead of large textures
- light souces add (lots of) time
- transparent objects add (lots of) time

Re: 3D Video Rendering is slow

Hi, it's a late answer, sorry... but you may still be interested by this tutorial about making and editing videos with Sweet Home 3D which proposes many tips to avoid very long rendering time.
