    Dear Sketchucation community,

    (first of all, sorry if I post in the wrong subtopic. Ididn't find a subtopic belonging to my issue).

    Is there any plugin or software that generates a simple and fast equirectangular (360x180 scene in a 2:1 width to height ratio image) projection of a Sketchup scene as viewed by the camera ?
    By "simple and fast" I mean simply rendering what I see in Sketchup, without the complex (and process intensive) photorealistic light, reflection, refraction & all.

    There's this plugin, "Cubic Pano Out", that does the job, but it does so by generating 6 pictures (up, down, left, right, front, back) to cover the entire field of view of the camera.
    We have then to use another software to assemble them into an equirectangular projection.
    Is there a plugin/software that generates the final projection at once ?

    There is also for example "Podium for Sketchup v2.6". This one generates the scene at once, but also generates the complex photorealistic setting that I don't need.

    Thanks.

      I don’t know of a way to get a eq pano straight out of SU without rendering software but you could try this to convert the cube map you have to a eq.
      https://360toolkit.co/convert-cubemap-to-spherical-equirectangular

      The goto software is ptgui, it’s not free but there is a fully functioning version that watermarks the results

      Edit, I’ve just re-read what you wrote and you mention already having and not wanting a 3rd part converter … Opps, sorry

        Found this one: cubicVR. A free plugin by Sketchup Podium.
        Description and download here:
        https://www.suplugins.com/podium/help/cubicVR.php

        It generates the equirectangular output in one clic.
        The drawing lines are pretty sketchy, but it's sufficient for my current needs of fast prototyping.

        Though, I would be glad if someone knows of a cleaner alternative.
