It's up to you, no doubt, but I only wonder how did you get 168 Mb ?

that is what is mentioned on the download site for the zip file.

))), understand, here is a version optimized by ZBrush retopology algorithm:

Here it is. Also increased the light intensity a tad (personally, I
prefer the darker version where the surroundings are less visible)
The optimised mesh has the same quality as the 'heavier' one. Well done!

I like how it looks now, but this is your project - your rules :)
And don't you think that it's time to animate it now (putting on
turntable first) ?

This is Pixologic's magic, not mine :)

cheer away :-) link to 6.1M zip, 17M mesh. looks unchanged, afaict. (started
playing with a rose quartz material, so sample scene is .. untidy)

neat. when I use the 'vase_3.pov' with shadowless lights and explicit no
reflection on anything, and use a srgbft pigment (like yr recent "gyroid"
thing), I see interior "features" too.

Very good.
I did my transformations (on the original converted OBJ files) in
Poseray, centering and then rotating the vase, and dropping it to y=0,
/before/ exporting to POV-Ray.

In my studio set-up I used trace {} to put the vase on the 'pedestal'.
The 'base' of the vase effectively is situated at y=0 in the geometry file.
//Bounding Box....... from x,y,z=(-1.8839052,0,-1.7086791)
// to x,y,z=(1.8823464,4.72023337158,1.6314062)
// size dx,dy,dz=(3.7662516,4.72023337158,3.3400853)
// center
x,y,z=(-0.000779399999999986,2.36011668579,-0.0386364499999997)
// diagonal 6.90082777701024
And the same from the 'optimized' version (note that for some reason,
the size is much larger. yesbird?):
//Bounding Box....... from

Yeah - I did an intersection to slice it in half, and was wondering what all
that was about. Might be just poor mesh structure due to conversion from a raw
point cloud / stl-obj-pov .... ?
