Re: rendering best-quality photos. Well... win 7 x64 installed, so now it uses all the memory, and java x64 plus your sweethome .jar, and now (finally) task manager reports java using something near 1.5gb rather than 650mb. The scene it's rendering is still not *fast* exactly, but there is visible progress, which is more than it did before. More tellingly, CPU use is at 100%: all 4 cores at the top of the graph... never seen that before on this system. It has to be possible that it's CPU which is now throttling the process, seeing as I told Java it could have 2GB and it's not actually using that much. The CPU is a quad-core intel [just looked - Core 2 Quad Q6600 at 2.4GHz], but not the latest kind... Does Java (or Sweethome) use the graphics processor? I wonder if there's any setting for that... |

Re: rendering best-quality photos. as for sending the file it's a bit big... about 31MB. |

Re: rendering best-quality photos. 100% CPU usage is "normal" on any renderer, if your worried grab something like Core Temp and monitor the cpu's temp, mine usually runs at 55 across 8 threads (i7) rendering a 2gb scene |

Re: rendering best-quality photos. Hello, I have the same issue : I have a quiet strong config (last imac high end config) : Intel Core i7-3770 3.4 Ghz, 8GB of RAM, 3TB Fusion Drive, Nvidia GTX 680Mx If i want to make a video @HQ quality in Full HD resolution, which last 1m30 (1 pass around the house, exterior => means around 2500 pictures to calculate) , it asks me... 10 days !! Do you thinks is there a little problem ? If not, what kind of computer do you need to be able to use HQ quality in video at 1920x1080 resolution ?? PS: even at 720p resolution, the time asked is greedy |

Re: rendering best-quality photos. Juju, Questions about rendering times keep popping up with a certain regularity. That's why there's a section in the FAQ dedicated to this subject: How can I speed up the rendering process in photo and video creation panes? One other suggestion is to make invisible all models that will not appear in your picture/video. Hans ---------------------------------------- Hans new website - under constuction hansdirkse.info |

Re: rendering best-quality photos. Look at the FAQ How can I speed up the rendering process in photo and video creation panes? to see if any of the tips could help you get a smaller rendering time. You could add to these tips some ideas like mixing videos and high quality images like in this example or this one. Do you thinks is there a little problem ? The estimated time is indicative and based on the time taken to compute the first images. Actually, it could be less or more according to the characteristics of each rendered image.When I programed the video creation feature, I added the estimated time to inform users and help them decide if it would worth it to wait or not. Personally, I wouldn't take the risk to wait more than one day, but I got some reports from users who successfully waited days for video completion. For your information, there's very little chances that I can optimize this tool in the near future. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |

Re: rendering best-quality photos. Hello, I forgot to mention , it is the first thing I did :) Of course I have increase memory to 4Go. This doesn't change anything and I notice, the amount of memory used is not very different between paramater in plist.info set to 1GB or 4GB. I didn't notice other parameters I could tweak ? Regarding object I can set transparency to 0: Does this concern all object of the whole project ? For instance : If I render the ground, I should disable of object which belong to First floor ?

Re: rendering best-quality photos. Juju, One other suggestion is to make invisible all models that will not appear in your picture/video. Hans I gave a try and the result is really hugh : For rendering 2917 frames (720x405) I drop from 125 hours to... 18 hours ! Much better. In a perfect world I could do full hd rendering... :D |

Re: rendering best-quality photos. You could add to these tips some ideas like mixing videos and high quality images like in For your information, there's very little chances that I can optimize this tool in the near future. Mixing video and realistic pictures is a really good idea, thxs for the tips ! Regarding optimization, what do you need (time of course :) ) ? Maybe I could help or find some help As I read in another post, using GPU (or better OPenCL on OSX which managed CPU/GPU dispatching) would be really efficient ( GPU engine are now highly flexible ) regards, Juju |
