Hello there! My version of that image was rendered in Blender using their equirectangular/panorama camera setting. The way Valiant360 works is to take a texture and draw it onto a sphere in 3D space, then a virtual camera is placed in the middle of that sphere, and it simulates being surrounded on all sides by video. All sphere textures should be a 2:1 aspect ratio, exactly twice as wide as they are tall, and your videocard will be happiest if the texture's dimensions are a power of 2. So, make sure your image is one of these resolutions: 1024x512, 2048x1024, 4096x2048.

Hope this helps, if you post the image you're using that looks distorted, maybe I can give you some more advice.
