Hi,
I made a simulation of a hexapod in wich the movement of the top platform seems to be caused by the extension and cotraction of the actuators (see hexapod screen.avi).
But when I render the simulation the actuators dont move anymore. (see hexapod.avi)
Any idea what causes this?
Thanks,
Janeau
No one who has seen this before or who might know what is the cause of it?
what do you mean that the actuators don't move? i can see that they move, but it's only a 1s animation in comparison to the other one where they do more moves but in 6s long animation.
So... I'm not sure what is wrong..
When I use solidworks screen to output the animation (hexapod screen.avi) you can see that the coil like part of the hexapod extends.
But in hexapod.avi the bolts move with respect to the upper ring, they are not fixed anymore. When you loop de video it is maybe easier to see.
What options did you use?
It appears you chose "Save as type = AVI" and "Renderer = PhotoView". How many FPS?
Your rendered AVI file is very small. Was the rendering interrupted?
When I want to render an animation I use:
"Save as type = Series of BMP" and "Renderer = PhotoView" with "FPS = 30"
This generates 30 rendered images per second of animation.
I then use QuickTime Pro to stitch all the frames into a .MOV animation, which I then export as MP4 (a more common file format than AVI).
I like this method because I can break up the rendering into time ranges and I can interrupt an overnight rendering job when I want to get back to work in the morning. Then start rendering again at the time I interrupted it. The files are all numbered sequentially so it is easy to redo a short segment without redoing the whole animation.
If you are using the "accelerated" rendering option that might be the issue. The accelerated option doesn't support geometry changes (deformation). I can't actually view your videos (I receive a codec error).
Hi Rob,
Here are two links so you can watch the videos in your browser:
Hexapod screen.avi - Google Drive
There is actually no deformation going on, i faked it, two parts of the coil just move into eachother.
Regarding the accelerated rendering, i've read somewere else that making a really small cut should disable it.
But I didn't get a notification that accelerated rendering was disabled. Is there another way to do this?
Making a cut should work as long as its an assembly level cut.
Looking at the video it should work in accelerated mode. I'd still give it a try without using accelerated.
What version of SW are you using?
Disabeling accelerated rendering actually solved the movement problem. The cut i made was not on the assembly level. But now my rendered animation has the wrong appearance, it's white. See the video
When you go to PhotoView 360, what do you see? I think you will see it matches the video.
Do you have more than one display state? If yes, try switching to the other.
The final render window shows me the correct appearance during renderig, but the saved results are white. When i click on recall last render after rendering, it shows me the same images, when i save one they do have the correct appearance. Very weird.
What do you mean by the display state?
The animation is saving the ambient occlusion output. Uncheck the ambient occlusion option in PV360 Options property manager (near the top).
You are correct again. Thanks!
Think of Display State as a "configuration" but only for appearances. So you could have one display state with the part painted red and another display state with it showing wood grain. You can view current display states (& add more) from the bottom of the Configurations tab.
Cool little animation by the way
Hi Bill,
Yes, i did select avi and photoview with 30 fps. I only rendered the first second because that is all i need to check if the motions are correct, which they aren't. My animations don't normally take that long to render so i export it straight to avi.
what is 'accelerated' rendering option?
Accelerated rendering saves all your frames to lxo and then processes them in PV360 rather than send one frame to PV, rebuild, send another frame, etc, etc. It can save a lot of time rendering (up to 30%) frames but it only works in some cases.
but can you select somewhere that you want to use accelerated or not - renderin (or is it automatical)?
If you have a "feature" in your model accelerated rendering doesn't support you are asked (at save time) if you want to use accelerated rendering or standard rendering. Otherwise, accelerated rendering is used by default.
for this, and imho, don't use avi (very problematic)...
..as has been suggested.. save the frames out as image files (png, bmp..) and compose/edit.... much better control.
Saving the frames as bitmap files gives me the same results as saving the animation as avi.
Making a cut should work as long as its an assembly level cut.
Looking at the video it should work in accelerated mode. I'd still give it a try without using accelerated.
