Help Needed to Reduce File Size
-
I have created a number of small decorative items (pillows, plates, decorative objects etc.) in SU by using a jpg of the item. I would like to post them on SU Warehouse but they all seem excessively large for what they are. If anyone is able to reduce the size of the attached .skp and to let me know how – it would be very greatly appreciated.
These are steps and the resulting output file sizes:
jpg to PhotoAnimate-205 KB
PhotoAnimate to .3ds = 187 KB
.3ds to Simlab to SU = 3,367 KB
SU using Cleanup = 3384 KBIt seems the increased size of the output is in saving the .3DS file as .skp. There are a number of formats in Simlab to export the 3DS file to, .skp being the most obvious. I have tried a number of them such as .dae,.fbx,.obj (with material),.obj(based on structure) but there was not a significant size reduction and in most cases the object was very triangulated or had lost the material mapping altogether.
I’m using SU8.0.4811 and was not able to load TT_Lib_V2 so using Cleanup may not be working at all.
To use one or two pillows in a scene may not be too critical but if the files can be reduced it would certainly be way better.
(PS .3ds file type not allowed to attach to this post)
Thanks for any help.

The cushion can be mirrored along Y as the mesh is symmetrical. That will reduce the file size to <2mb

Thanks for the reply, Rich
The mirroring part happens in the Animate program, prior to importing into Simlab as a 3DS file so when it is exported as a skp it is fully formed as a 3D object. So I'm not quite sure where you suggest the mirroring takes place. Leave it as a one-sided 3d form to be mirrored once it is opened in SU?
I tried that and it did reduce it by about a third which is pretty good-thanks! Probably the best I can hope for when using a 3ds import.
Thanks again. -

Mirror the geometry to the back.
To reduce the poly count export it to .dae and import to Blender and add a Decimate modifier with a .15 ratio then apply it.

I don't have Blender yet but will download and give it a try.
I have about 1200 of these created so I know what I'll be doing in my spare time for the forseeable....no batch process. -
A job for Mootools 3Dbrowser with Polygon Cruncher?
-
Yeah, Poly Cruncher can get it down to 100 Faces and 788kb in size.
At this point the alpha in the png is contributing to 70% of the file weight. If you save the texture as jpeg you can save a further 500kb...
-
impressive, roughly 3.3MB to 203kB, that's some optimization!
-
Excellent! I think that may be what I'm looking for

Just to update this info for anyone else trying to reduce the file size of a 3ds import into Sketchup.
Downloaded the trial version of Mootools 3ds Browser with Polygon Cruncher.
Batch processed a few .skp files but wasn’t able to open as they save in V16 and I’m still using V8.
(To save to other versions of SU may be an option in a later version of Polygon Cruncher but not possible right now)
Redid a batch process at 75% optimisation using the original 3ds files.
Opened in Simlab Composer, mapped the corresponding material file (using jpg not png) and was able to save/open in SU8.
The file size went from 3,230KB down to 707KB
I’m really happy with these results.
-
As far as I am aware it saves as SketchUp v6. Not v2016.
At least my licensed version does.

I did contact Mootools Techsupport and they responded:
"No there is no way to export using V8 version. This is an idea to add to an upcoming version"
But I can work with my convoluted path for now to get these results. It's been a hit and miss search for quite a while so this is progress-for sure!
