Re: VERY slow video rendering
wow.. that is a long item to render. i would bet if you had a i7 PC, more RAM, and a larger GPU card and a SSD HD's it would go a lot faster. if you want I can test it on my PC. and even do a Webex with you to show you how fast it will take. let me know. can I ask what you are drawing that take that much CPU? i bet it is a awesome pic

Re: VERY slow video rendering
So... Does anyone have any idea what this app was designed to render with??? What I mean is that some apps use GPU to render, while others use CPU, and still others use both equally good or bad, as the case might be, so which category is this app??? Was thinking about building a computer just for renders with this, but after seeing people with extra fast setups having the same problem as me, maybe I shouldn't... A 30 second video takes me at least 3 days to render, and that's with the whole 8ft X 17ft room filled with stuff on one wall, and LED lights on the top of the walls... Anyone, perhaps the author, know the answers???

Re: VERY slow video rendering
HI all. Its now mid 2022 and GPU Hardware rendering has become the main thing. It would make rendering the video's a LOT faster. Is this something to be expected in sweet home 3d? Thanks!

Re: VERY slow video rendering
Try YafaRay renderer in the new version 7.0, but don't expect Sweet Home 3D to be able to use GPU for rendering soon.

Re: VERY slow video rendering
Hi,
I've been using the YafaRay engine for sometime and now all of a sudden what used to take 4 minutes to render a fairly simple floor layout, is taking nearly 18 minutes. I have now idea why!

Re: VERY slow video rendering
Did you try to simply relaunch Sweet Home 3D? Maybe a part of the memory used by YafaRay is not freed after each rendering and the program starts to miss RAM.
