CubeTexture orientation

[V!nc3r]

Hi all,

I tried to set up a scene in the playground with a custom cubeTexture, but playground doesn't like it https://www.babylonjs-playground.com/#1XOKHQ#1

So for now my simple scene is on my ftp : https://www.nothing-is-3d.com/tmp/cubemapBJS/

This is a screenshot from the photoshop file used to generate the cubemap (based from the famous tropicalSunnyDay)

Exported files are located here : https://www.nothing-is-3d.com/tmp/cubemapBJS/cubemap/

 

And here what i get, check how the pz is mapped :

So simple question why the cubemap is inverted ? Is it me who is doing it wrong ?

@V!nc3rYes, i think it is something about how reflection works, and also how the (link to a random blog: ) cube map is defined

so here is the short version

you see the px reflection and your camera starts -z. just think about it.

Ouch, my topic seems to be a n00b question indeed. I don't know why I don't drawn a parallel between reflectionTexture and mirror IRL... Can't wait vacations to have some rest

@Sebavan has a really cool blog, check this out:

@rich can you see this gif? would be kind of cool, if i can phrase a babylonjs - playground with a live prieview (like shadertoy), maybe also useful for other engines in this forum.

@Nabroski This is not my blog but one I like to read.  

This is the blog form the director of rendering research at Unity.
