Hello,
I saved a simple vrscene file in 3dsmax that contains a Teapot in center coordinates. but when load as a preview file for material, there is a massage that I showed in attached files.
Hi yones,
This warning means that the scene you are trying to open is not recognized to have a valid object that will be used for a material preview. You have to add an user attribute ‘__thumbnail_target’ (in the object’s properties https://drive.google.com/uc?id=1DPBx…JlBDox-41AZ )to a mesh in the scene that you want to be listed in the Preview mesh list. Keep in mind that when you are loading a preview scene you are replacing the current one. That means in the new scene has to contain a render camera and some lights(if you do not want to set the environment texture manually afterwards).
I am uploading here a sample scene with a Sphere and a Teapot for you to examine how they are setup and if you wish to add more objects to the preview list, add the user attribute ‘__thumbnail_target=#’ in increments:

When exporting the scene to vrscene keep all objects visible: https://drive.google.com/uc?id=1C6H_…IzavKivENmBbKw

Thank you very much for the information you provided me.
Could you share the Archive file because some textures are missing? :p:p
Those textures are not used anywhere so you can delete them. I have re-uploaded the scene and you can re-download it.
.
LOL, I would only have got this by guesswork and all I guessed was wrong when I spent an hour trying to make this work yesterday. Now I see why.
Would it not be simpler to provide an example as in your image (at least in the docs), which perfectly provides a solution, rather than
what I’d argue is an extremely misleading/confusing error message and the accompanying ‘example’?
The message’s syntax implies that what should be used is what comes after the colon, which is obviously not the case.
The ‘example’ given in the ‘show details’ panel just further complicates the issue imo 
Hi fixeighted,
Yes, the docs will be updated with this information.
Best regards,
Alexander
