Spherical sky

Post by SuziIde » Tue Mar 30, 2021 6:32 am

Hi All, I'm new here and I've been working through the 'Twilight Render Tutorial Quick Start Introduction' tutorial.
I've got to the part where you insert a spherical sky which I've done and this is what happens...

Does anybody know what has happened and how I fix this?
Thanks

Your sky image is not seamless. So you are seeing the seam. That is where the left-hand side of your sky image is being stitched together with the right-hand part of your sky image.

Fix it by making the sky a seamless sky in a photo editor. I like Photoshop for this. The latest versions of Photoshop allow you to use AI to fill in what is missing in a scene. Or, you can make the canvas of your sky image 2x wider, and mirror your sky image so that the sky will match at the edges. See example below:

After doing that, be sure to add some grass and sky top and bottom to make the final sky image of 2:1 proportion 2 width and 1 height. So 4000px wide and 2000 px high for example.
