feature request stop-motion-stl about stop-motion-obj HOT 17 CLOSED

Thanks for the suggestion, though I can't promise I'll be able to get around to it anytime soon. Just so I'm aware, is it common to have animation software export sequences of .stl files, but not .obj files?

from stop-motion-obj.

Hi Justin. I would say for more scientific applications yes. For example, currently, I'm trying to use paraview to export a vtk file sequence so that I can use them in Blender, but the only option in paraview is to export to stl 👎

I've got some time today. Lemme see what I can do.

from stop-motion-obj.

I added the branch "stl-ply" that supports STL files (and PLY files, while I was at it). Go ahead and try it out. I'm gonna merge it into the master branch at the end of the day unless we find anything horribly wrong with it.

I have been trying to get this to work, but I don't see anything:

It looks like all of your .stl files are empty.
(as a side note, since the file numbers aren't zero-padded, they'll load in a weird order)

from stop-motion-obj.

Ah of course, fixed that and the filename issue. Currently loading (taking a while, I should have probably tested a smaller case, but let's see how this goes...).

Cool it works for a small sequence!! Here's the problem though. For large sequences I think it crashes due to memory ...

from stop-motion-obj.

Any chance you could share a large one with me so I can see up close?
Also, what's "large" and what's "small"?

from stop-motion-obj.

Of course:

The original sequence with almost 900 steps crashes my blender due to memory (12GB). However if I create folder with say 100 of the stl files it all works.

Warning the file is almost 8GB (some of the files are still uploading)

from stop-motion-obj.

Thanks for the sample meshes. (I'm done with them, so you can free up your Dropbox space whenever you want)

Yeah, 8GB would probably do it! I'm not sure why, but Blender seems to inflate the file size of imported geometry. Your "short" sequence takes up about 139MB, but when I import it to Blender, the resulting .blend file is 183MB. To make it worse, Blender uses 833MB of memory with the sequence open. I might have a way to get memory usage down, but I don't think I can get the add-on to work without holding all of the meshes in memory.

I'm closing this issue, but I'll see about lowering memory usage.

from stop-motion-obj.

No worries. Thanks for the added feature! I guess now you have to rename the rep :P

from stop-motion-obj.

Yeah, I just might have to change the name. I'm glad I could help.
I'm gonna merge the branch soon. You should snag the latest version once I do; I made a quick change that cuts memory usage nearly in half.

from stop-motion-obj.

Great. Also do mind telling me how I can specify the fps of the sequence that I import?

from stop-motion-obj.

FPS is left to Blender. The addon will load every frame, but Blender's Frame Rate setting will control the playback speed. See the attached screenshot for how to change it:

Is this what you're looking for?

from stop-motion-obj.

@musm Do you happen to use Stop Motion OBJ still? I'm working on a new version which includes a feature that might solve the "too large to fit in memory" problem.

from stop-motion-obj.

Hi @neverhood311 it's actually been a while since I've used Stop Motion OBJ
