Skybox troubles

It may be that weā€™re limiting maximum resolution right now. Didnā€™t get to check it yet

22

Weā€™re not limiting resolution but when exporting in a lower resolution the skybox gets indeed less sharp - in 4k its big because of the EXR exportā€¦ As a workaround for this case Iā€™m suggesting you set the resolution to a low size and make a C# + ts script using a ā€œImageReferenceā€ type (e.g. public ImageReference mySkybox) and then loading that as your skybox using the THREE.TextureLoader

23

@AeistDesmos in 2.50.x you can now use the RemoteSkybox component and just reference your skybox texture there

24

But also make sure to set the skybox texture size to a lower resolution

Okay thanks !

Hi !

I compare the two render and thereā€™s differences :

The render with manual CubeTextureLoader

And here, the render with the remote skybox (with the same texture) :

How does it look in Unity?

31

Is your project set to linear color space?

32

I think, itā€™s because that the skybox in the second solution is created by ā€œsphericā€ skybox and not cube

Itā€™s look the same

35

Then its correct right? The cubemap texture is probably not set to sRGB when you load it

36

this one

37 
this.context.scene.background = new THREE.CubeTextureLoader()
            .setPath( '../../include/' )
            .load( [
                '../../include/sky_4k_cube.jpg',
                '../../include/sky_4k_cube.jpg',
                '../../include/sky_4k_cube.jpg',
                '../../include/sky_4k_cube.jpg',
                '../../include/sky_4k_cube.jpg',
                '../../include/sky_4k_cube.jpg',
            ] );

For the first one I use this line of code

Do you know how to use CubeMap with remote skybox ?

May I ask what your goal is here?
