user854 Yeah, definitely agree with raider968 as far as the 200 degree fisheye being the likely culprit with the distortion you're seeing, but only if you're talking about SLR Original scenes in combination with Skybox.
I'd suggest you try:
1.) renaming the files to their original names (aka the names they had when you downloaded them). Changing file names/extensions can alter how they are displayed.
2.) try playing the scenes in the SLR app or DeoVR (and make sure whichever app you use is up-to-date). Most other apps including Skybox are not able to correctly play the 200 degree scenes like SLR Originals, and instead jam them into 180 degrees resulting in distorted scenes.
3.) If you're specifically NOT talking about SLR Originals scenes, then I'd suggest you still try the SLR app/DeoVR instead, and if that fails post a few scene names/links here as example. Always a chance (especially with older scenes) that you're seeing things correctly and the models straight up are just too big. Tech has improved a lot in the past few years haha.
