Not too sure what you mean when you say "saving", saving what?

If I export a mesh as 3ds then import it, some objects are displaced.
If I export a mesh as Obj then import it, it is fine.
Both methods loose any hierarchies built using "empty" objects.
Using 3ds I have to scale up by 100 after importing.
3ds imported model is not as smooth as the Obj one. (See attached image, 
3ds is the one at the top. Incidentally Blender hung after Pov rendered 
this and I had to cheat to render it to post it here.)

Question:
How do you pass commands from Blender to PovRay. Such as output types 
and save file?
How do you pass PovRay materials in Blender?

I'm too new to Blender I should not be trying to run before I can walk.
But heigh ho! that's life.

saving the imported 3ds object as .blender file first before doing a 
povray render from with-in blender ... more of a curiosity on my part 
than anything else because of the problem that i'm seeing!

it /seems/ to be with how the object was built. now i'm speaking in pov. 
-z behind, -x left +x right.

example: my current project 8 melted candles on a box, wax dripping down 
over the edge.  the candles are roughly in two rows and the x position 
is flipped: instead of 1-2-3-4 i get 2-1-4-3. i took each of the candles 
(and wicks) cleared rotation, location, scale and origin, then properly 
built the object centered at 0,0,0 the placed them in the scene. setting 
of the origin seems key. now i'm able to select the wick of each candle 
then snap 3d cursor to the wick for /proper/ location information, 
because in povray i'm going to place a media/light source flame on each 
candle.

the render options tab (little camera)

i don't do that ... usually just add simple texture to identify in 
scene. i do material work either in pose or pov ... ray

for sure i'm no expert either

That is what I thought you meant but I wanted to be sure.
It does not seem to make any difference to me.

What version are you using?
Blender seems to be updated daily and I now appreciate PovRay's version 
control, more than ever.

My problem (one of them ;-) ) was scenes that I had created before 
activating the PovRay addon did not render with Pov. But exporting the 
models then importing them as meshes would allow me to render them in Pov.

That makes sense. I do try to create things at the origin. But it is too 
easy to right click instead of left clicking to select. And change the 
location of the 3D cursor.

Yes I remember. But since I am starting out I'll try to do things properly.

well now i'm not so sure about that anymore ... curious i did some 
slightly more than casual tests. i'm starting to think it's how poseray 
is exporting or how povray is parsing. the images are appropriately 

output from poseray.

It's not something silly like PoseRay's default export handiness is 
Right handiness?

I generally only export the geometry and change the handiness to Left 
handiness (PovRay default).

nope ... on the input tab reorient 3ds and dfx models is checked if 
that's what you're talking about. i do however see flip options in 
groups tab

No, it is in the PovRay Output tab.
World axis orientation, again PoseRay scene (Right handiness)

I use PoseRay 3.12.2 as that is the highest version that Bishop3D will 
import.

Yep. Typically a world orientation choice in Poseray's POV-Ray Output, 
like Stephen said, right-handed vs left-handed. Same in latest versions 
of Poseray.
