I'm trying to experiment with an animation project that requires the use of a spherical background image. The image I wish to use comes from a program that outputs six images; one for the top, bottom, left, right, front, and rear views.
Originally, I tried getting these stitched using an external program to create the spherical projection that can be used for a background in Blender. This worked perfectly, as far as seeing the image was concerned. However, the only free tool I could find places a watermark on the image.
So before I ask if a fully functioning free tool exists, is there a feature or add-on in Cycles that can create the intended background using the available images?
If it matters, the node setup I used for the watermarked image was:
