Hello,
Surely some of you have solved it. I need to send the client a 3D model from LWO (including texture, UV mapping), but in a portable document format independent of the OS. This purpose would best suit the 3D PDF formats. Do you know a tool to convert LWO / LWS 2015 to 3D PDF?
Thanks for suggestions

Erikals: Thanks, I found this thread in my search. Unfortunately, I was hoping that the issue had moved somewhere over the course of time. Looks like not.

You can do it this way:
Download VirtualDub, Camtasia, or other desktop recording software, and start recording and spin object(s), scene, in viewport, or VPR, and then send recorded movie.

Or convert it into UNITY and set it up as an Augmented Reality Display

I have done it several times few years ago. If I remember correctly I exported Collada from LW, then imported to Photoshop and then exported to U3D format and then took it to Acrobat for 3D PDF. UV mapping worked also after I figured it out. It takes only few minutes when you know what to do. If you still have problems I can try to find my files and workflow to help you further.

Now things come back to my mind! There was also an issue with rotating the object in 3D PDF. It was little bit clumsy because you can rotate the object all directions and rotating wasn't that smooth. I managed to find some script that I used to make the rotation smooth in PDF and also lock some axels to make it easier for the customer.

Designsparks can turn obj files to 3d pdfs quite easy, it is free, you do need to register with some personal info on their site though, it has a simple export button..next to the 3d model download you have export options and from there you can export your model to pdf wich allows anyone to rotate measure a model.

Import format for Designsparks is obj, so save your lwo model as obj then import to Designsparks, then just click on export options and select 3d pdf format, not sure about the uv maps though, I had a go at designsparks some months ago at work, and it is easy to use, has non destructive workflow, adding dimensions and rounding fillet has widgets to do that or change dimension values after intial radius is set etc, it also has a nice pattern tool to create holes for instance in a radial pattern.

I need to install it here on my machine first then I may be able to showcase it, perhaps at the weekend.

Just installed it, it was a while since I used it at work, so I need to get back working with it, check the print screen, and if you want to fillet edges, just use the pull tool on any edge.
But look at the print screen to guide you where you go for exporting it from designsparks, in this sample screenshot..there is only a solid mode in my sample, but other format such as obj will work (no import option needed) it also imports sketchup and stl and step files.

What about Marmoset Toolbag? You can export the object to a viewer which requires a web browser.

Once in acrobat, anyone can view the 3d object without having a 3d software installed, by default and security reason, a pdf file with 3d content is inactivated in adobe acrobat, so you just need to activate it, there is a message bar at the top of the imported document.
I do not think its possible to view uv textured objects in pdfs.

you do get a lot of options to use, like cut through planes as in this sample, I loaded a make human mesh in to lightwave, then exported to obj and loaded in to designsparks then epxorted to 3d pdfs, you also got some measure tools, you also get
layout views as they were made in designsparks so clicking on those will apply rotation based on that...

I did this a lot for clients that needed to interactively approve rigged characters for their game. This is easy to export as fbx to unity and the superior option - they can look at it on their mobile devices (from an email link to the unity app) super easy. Gotta love Unity.

It's has a bit of a clunky UI and you have to bake your textures out first, but we've used Simlab (http://www.simlab-soft.com/)to create 3D PDFs with fairly good results for more straightforward models. If I recall correctly, exporting to FBX from LW works best.

@Prometheus THX .... Designspark mechanical I tried ... Unfortunately, it does not seem to support texture import .... otherwise the simplest workflow

@Sami .... I do not have a UNITY license

@ Devin ..... Yes, Simlab was also tested in the trial version, unfortunately after the expiration of the deadline is unusable

Generally ... I am looking for a non-commercial solution ... the number of such generated models is assumed to be max. 5/year

Thanks to all for your help and suggestions

Unity licences are free. And there are hundreds of tutorials online.

Underlining this. UNITY is free, and the dox are THE best I've ever seen.

How difficult is it to set up a simple rotatable model in Unity? Any chance that you can also add labels with pointers that track with the rotation? I'm guessing that you can set up parts/layers to turn on/off? I've always just assumed you needed programming/scripting knowledge to make anything work with the engines. It's def something that I'd like to explore if time ever permits...

It's quite easy in Unity but you need scripts to do it. A great thing with Unity is that there is a lot of ready made scripts so you don't have to do all the scripting yourself. There is also the asset store where you can find scripts and plugins that do what you need. I use a visual scripting plugin for Unity so I don't have to do regular scripting. If you want to do html5/webgl things in unity its easy but not optimal, unity creates very big files.

SketchFab is one more option. And a lot of fun - also easy to add extra 'eye candy'.

Client only needs a browser. Full screen is supported, and a Lightwave exporter is available. Notes, views, and simple viewer interactivity are easily added too.

To be fair, the OP was probably observing that Unity is Free for the hobby version/use. If you are using it for work they do want you to buy licenses for work/pro use.

Another option: Blend4Web. A free add-on for Blender that exports your scene directly to a html file, and defaults to a viewer - no scripting required. Also offers a visual (nodal) interaction editor and full support for animation (which can be controlled with the visual interaction editor). As long as you do not intend to publish to the web, as far as I am aware you can use it to send 3d files for viewing to clients.

Blender 2.75 is the best version for importing LWO models, and I advise anyone to first open their LWO models in Accutrans to check for problems, and re-saving it. I found that this workflow works best to retain the textures, and it is easy to fix reversed normals. You may have to fix the materials, though.

only if you make over $200K per year and are publishing games. this would be fine
