    Is there a way to import/create a new skybox?

    I want to place model in a forest scene near lake (for example).

    I’ve found numerous forest/lake scenes online, even AI generated, in all sorts of formats.

    That said, I have no clue how to import them or even IF this is possible?

    Any thoughts? THX 🙂

    Hi,

    -Right click on the 3d camera view’s background>scene properties

    -Change background, type from 2D to 3D

    -right click on any of the existing skybox images>add new

    -select texture>select>upload your custom image

    Thanks, this helps locate where I need to focus efforts to add a new SKYBOX.

      <li style=”list-style-type: none;”>
    • Some images are combined “flat” or “wrap-around” panorama format.
    • Some images consist of 6-individual cube face images/files.

    <p style=”padding-left: 40px;”>Neither seem compatible with Envisioneer which seems to want a singular image depicting the 6-sided-cube.</p>

      example: (1) Obtain 6-cube images; (2) Arrange images in Skybox 6-face fashion; (3) Save group as image; (4) Import as texture?
      Does scale or sizes (X,Y) of the faces matter w/r/t top/bottom or N/S/E/W views?

    I tried to import a generic skybox of a forest, w/o success (see images)
    I tried to make “white” area of image transparent as well. Neither worked.
    As a test, I also applied the sunset skybox provided by Envisioneer – which did work.
    Both were used “spherical” option (as did standard images)

    Any clue what I am doing wrong?

    The skyboxes from Cadsoft are images but there are several steps involved in creating them. You can create your own by following these steps https://www.interlopers.net/tutorials/28841/create-a-skybox-from-photos
    Or you can go the AI route and type in keywords the scene you want to create, into an AI skybox generator.

    Yikes, the photoshop version seems quite complicated (at this time), as I am somwhat unfamiliar w/photoshop. I suppose similar geometrical calisthenics could also be done by pasting images into something like powerpoint, then move/rotate images, then save as what, a jpg?

    The reference to “All that’s left is to convert the configuration into six faces, compile, and voilà!” makes it sound easy, but is far from obvious – to a newbie such as myself. I can figure out how to build 6-face-cube, but what about the blank areas? Black? White? Transparent? Compile, huh, what? Does this mean use a program like Sticher to convert the 6-cube-faces into a singulare “flat/blended” image? Is this then the image that is imported into Envisioneer? Does format matter (jpg, tif, png, etc.)? More questions than answers.

    As such, I’m be forced – once again – to the AI option, which I already tried w/o sucess (likely due to formatting issues). It seems that there may be other requirements on the images imported – imposed by Envisioneer – that I/users are unaware of and are not stated anywhere else in documentation? For example, cube .vs. spherical, pixel sizing, or blank area definition of the composite 6-face-cube?

    Wishlist:

    1. Would love to see a complete example/tutorial of a (user or AI) generated skybox that actually works.
      Obviously the Skybox background is a wonderful visual tool/option, but users not being able to import personalized backgrounds (forced to use a few generic ones provided by Envisioneer), while appreciated, is limiting w/r/t conveying site plan visuals to interested parties that (say) want to see their virtual  home on their lot (rural, sub/urban, commercial/industrial), or lake/river/beach front, or forest/streams, or even perhaps whimsical scenes (Moonscapes, fantasy woodlands), or … … …
    2. Would love to figure out how to take 6 pictures around a house (Left-Right-Front-Back-Top-Bottom) and use that as background.
      This would be a nice Envisioneer feature:
      (1) Take 6 images w/camera;
      (2a) Import/Convert 6-cube images directly into Envisioneer, which converts them into a background.
      (2b) Use HomeView to upload 6-cube images, turn them into background, then download background back into Envisioneer.
      (2c) Import single “flat/blended” panorama derived from other parties such as 3DVista Stitcher?
    3. Seriously consider expanding catalogs to include more 3D backgrounds that are developed/shared by user community.
      AAerospace example VSPAirshow  allows users to download models as ‘templates’. Quite useful saving time getting started.

    p.s. Louisa … you rock

    Thank you for your feedback! I will look into it some more, to see if there is a more simple way. Also to see which is the best format to import into Envisioneer. I will definitely add to the wish list for you.

    Goodnews. (1) Downloaded some square images of a forest in 6-cube format. (2) Took them into powerpoint and arranged them into the 6-cube format. (3) Saved the image as jpg. (4) Opened image and sized it to 4096 x 3072 (4:3 format). (5) Created simple model (see attached). (6) Opened scene properties, selected 3d background jpg image (see attached). Note: ONLY 4096 x 3072 jpg  works. ALL other ‘supposedly’ available inport formats (tif, bmp, gif, and png failed). (7) This added a new background (see image inside looking out).

    Bad news: (1) ONLY camera views work, i.e. Quickview drops background. (2) the model seems to ‘float’ above the scene ‘floor’ as opposed to resting on it (changing floor location does not help) or wrapping around the ground floor. The issue might be that the forest floow image needs to be made into the terrain image? How that’ll mesh w/the 3D background – Dunno? Will try later.

    The result of using the forest 6-cube floor image as the TERRAIN image, did not work well.skybox.ground
    p.s. the prior attempt top upload the sample bld file also failed. Below is another attempt to load it as a zip file. We shall see if that also fails.

    Thank you for the update. You can also try this as it is the best Cube Map generator compatible with Envisioneer. Just remember to import as a jpg format.
