Textures and UV unwrapping

Hi Everyone,
I have been getting a real headache trying to get the textures to work with Blender & Octane. It seems like the only way to get textures to display in Octane is to unwrap EVERY object in the blend file, am I right? Please can somebody say this is not true??? I have thousands of objects in the scenes and I cannot imagine unwrapping all of them one by one - this would just take days if not weeks!
Is there any workaround, pleeeeeaaaassseee
Or can I maybe unwrap all objects at once?
Thanks for any helpful ideas!

That is correct. For Octane to display textures, they need to be UV unwrapped.

Thanks for quick reply.
Is this really how U guys do it? This makes making architectural visualisation impossible, unless someone wants to spend days setting up UV's? Especially that UV mapped textures don't export like I would like unless every plane has a separate UV. On a complex building this is just impossible...
Do U know if there are any plans to change this or at least get a UV mapping functionality from within Octane?
BTW, if I am correct - the texture cannot be moved once in Octane, only a scale tool is available?

When you are done modeling, join the meshes of all your objects by material and UV unwrap with cube projection (or any other method that will keep scale, but cube works ok with walls, chairs & other archviz stuff). Then fine tune the UV grid on the more important objects and export. Considering the amount of archviz in the gallery, people successfully manage this shortcoming. But, there have already been a lot of request for auto coordinates inside Octane and I don't doubt it will be done someday.

That's right, currently the only possible transform on image textures is uniform scale. (this will also be improved, I hope)

If you use Rhino then every Polygonsurface will inherit the parent UV chords (from the NURBS Surface).
But you will still be able to assign box, sphere, planar or custom mappings.
Rhino is great for modelling Archviz or Industrial Products.
If you are curios give it a try. There is a fully functional eval demo.

Thanks Matej - I will definitely try this. Hopefully this will help me re-render some of the models I have set up for renderers other than octane. Still seems to be a bit of unnecessary hassle. Fair enough though, these are still early days of octane, so I will just patiently wait for an upgrade
As for Rhino - I know it is great, I have used it before and I love it. However if you need to buy one license per PC for circa £1k - it puts me off a little bit. So - thumbs up for Blender ( for now anyway )!
