Hello! I am trying to render a fly-through video using Animation Tools in AECOsim Building Designer SS5 (08.11.09.747). With the Fly-through Tools I don't have the freedom I need - moving the camera and its target at the same time. The video is 2100 frames long. I have three files, all of them in a ProjectWise project folder. We use PW Managed Workspace. 1 - The master only contains the camera, the target, their paths and the animation script. 0,5 MB 2 - The elements file containing the modelled elements, mostly long pipes and their accessories. 62,35 MB 3 - The terrain under the modelled elements, a Y shaped, 600-by-300 metres mesh with 300K vertices. I tried to cut it up to 100-by-100 pieces using the Trim Surfaces by Curves tool but ABD is just working on the cut with no visual effect and a single click crushes it. 9,56 MB I ran a distributed rendering process on three machines. I used my own login on all of them so they could see the same folders. All machines ran 6 MS processors. 1 - The master machine, where I ran ABD and started the rendering process: Intel Core i7-4770 (8*3,4 GHz) - 8 GB RAM - nVidia QUADRO 2000 2 and 3 - The other two: Intel Core i7-4770 (8*3,4 GHz) - 8 GB RAM - nVidia QUADRO K2000D The Record Script settings were: - 1280x720 resolution - Windows AVi Format using Cinepak Codec (After some searching on the forum I found many recommendatios of first rendering still images then making the video using some other program instead of aiming straight for avi/wmv, which I will do from now on.) - Render mode: Luxology, with slightly modified (Anti-aliasing) Exterior Good Setup, Light Setup based on geographical position and time, Modeling Environment. - Record Range: 0-2100. (I have done some test renders with two machines which ran at a rate of 2 frames per 5 minutes. Based on this the whole 2100 frames should have been finished in around 72 hours. I didn't have time for a thorough test, so it proved to be a very inaccurate calculation.) - Motion Blur on (but should have been off). I started the rendering process at 16:30 on Friday. At 8:00 on Monday (63,5 hours) 246 frames were finished. This is the first 9 seconds of the video, which shows the whole field from an unmoving point of view, only the camera rotating (following the moving target). So the frames are nearly the same, but they were finished at irregular and increasing intervals: Friday - 78 finished frames in 7,5 hours = ~6 min/fame Saturday - 107 finished in 24 hours = ~13,5 min/frame Sunday - 53 finished in 24 hours = ~27 min/frame Monday - 8 finished in 8 hours = 60 min/frame Some exact times: #045 - 19:42 #046 - 19:44 #047 - 19:56 #048 - 19:55 #049 - 20:07 #050 - 20:13 #191 - 1:48 #192 - 1:55 #193 - 2:33 #194 - 2:28 #195 - 3:02 #196 - 3:16 #197 - 4:02 #198 - 3:53 #199 - 4:42 #200 - 4:44 Based on these time values I think only two of the three machines were actually working on the process. Questions and issues: 1., What causes the irregular image finishing times? How could I set up a smoothly running distributed rendering process which I can plan with (meaning it will not slow down to 15-20% speed)? Is there a formula? 2., Why does it seem that only two machines were working not all three? Why wouldn't it have worked if it were set up the same as the other two? 3., On some of the finished images there are missing elements. On attached picture frame 192-193-194 can be seen. On frame 193 nearly half of the pipes (all are solids made by the same way) are missing, while there is no such issue with frame 192 and 194. What can be the cause of this? 4., Continuing #1 about the "formula". Which part of the hardware is needed (more) in a rendering process? We usually check CPU and physical memory usage during renders. At single picture renders it seems that while working on smaller pictures (borderline is around full HD resolution) CPU runs at full speed with small memory usage, and image is finished in manageable time. But on bigger pictures CPU is nearly not running at all, while memory usage eats up all available RAM, machine renders forever and often stops mid way. A 3000x2000 pixel exterior shot of a four-storey house modelled in high LOD with Exterior Good setup starts rendering (on a single machine, no distributed rendering) at 15:00, next morning at 8:00 done around 5% of picture and does nothing in the next 6 hours, but the same set in 1500x1000 resolution finishes in half an hour at most. Tried to make big resolution single shots with distributed rendering, but yielded the same results. I would appreciate any answer or advice, because we don't have the time to experiment with all of the settings and options. Csaba Szabó BURKEN Ltd Hungary
