Question by Monkey-Science · Apr 06, 2017 at 07:26 PM · vrmeshesvideotexture360-degrees360

360 video stitching bad when using Sphere Mesh and VideoClip

Hello - I've been playing with the new VideoClip player in 5.6, which is working pretty well performance-wise with even 4k video.

The big problem I have is the stitching of the video on the Sphere Mesh is a total mess at the two poles and seems to introduce a general 'wobble' all the way through the image.

Is there a trick I'm missing for the material or the GameObject to make this smooth out? The video looks flawless when playing back in ViveVideo, Youtube 360 etc...

Thanks!

Download or generate a sphere that looks like this alt text

Equirectangular videos ( 360 video ) are made for these spheres. Unity's default sphere is more like a normalized cube.

To generate a mesh like this, take a look at this url: http://wiki.unity3d.com/index.php/ProceduralPrimitives

Just to make sure I'm reading this right: You're projecting a video onto the surface of a default Unity sphere, right?

If so, then you probably just need a higher-fidelity sphere model. The unity one is pretty low-poly, so the UVs get distorted near the poles. If you make a higher res one in a modelling program, the distortion will be reduced.

Thanks for this FortisVenaliter - very helpful

I'm playing with different spheres exported from $$anonymous$$aya - I haven't created a version as clean as current players yet and am also trying with Procedural Primitives.

When I have cracked it, I will post results
