Thanksrenderwiz, i did do some work in photoshop to crop a skybox to bring it down to a more accurate eye level, but did not try other tweaks as you mention. I have tried reducing and enlarging the skybox image size but with no change to the enscape view.

DPHORVATH , without any workarounds it's not easy/quite possible to simply rescale a skybox. A skybox is simply being created from a 360 degree image file, which includes all the information to be wrapped around the project, as a skybox. But in that regard if it would be scaled, or stretched, or anything of the likes, you'd run into distortions or weird behaviors very quickly. Still, we have a feature request on our agenda to help with this kind of scaling still, but this may not be easy to implement and/or probably won't be coming anytime soon. In that regard we can advice to play around with different perspectives when the skybox is used with context. Or of course refer to a different skybox.

I have had this problem as well and have basically given up on trying to create/use/edit skybox environments because they always come out looking hugely out of scale relative to the model. A scaling function would be a huge advance in the usefulness of the product. Thanks.

Hi!

I create a small 3D scene following the 3D First Person template. And as i see, there is a fog creating shadowing effect. How can i do this effect in my scene too? UPD: I found the fog in the effect menu.

Also, how can i do skybox there?

I'm using Unity and MRTK to create an immersive application for the hololens (similar to Holotour). In this application, I need to simulate the sky. In Unity, a Skybox is sufficient to show this. However, in Hololens, it is not. How do I go about showing the sky/what's on the skybox in my Hololens? Thus far, I have tried adding a render texture for a camera high in the sky to an inverted sphere (i.e. a sphere that encompasses the playspace and shows the material of the sphere on the inside); but that doesn't seem to work...

I would suggest creating a blueprint from your skybox, make sure it is set to movable, and then in the event graph add a rotating movement component, you can use this to set the rate of rotation. You may find you get better results using a skysphere/dome.

A skybox is a method of creating backgrounds to make a video game level appear larger than it really is.[1] When a skybox is used, the level is enclosed in a cuboid. The sky, distant mountains, distant buildings, and other unreachable objects are projected onto the cube's faces (using a technique called cube mapping), thus creating the illusion of distant three-dimensional surroundings. A skydome employs the same concept but uses either a sphere or a hemisphere instead of a cube.

Processing of 3D graphics is computationally expensive, especially in real-time games, and poses multiple limits. Levels have to be processed at tremendous speeds, making it difficult to render vast skyscapes in real-time. Additionally, real-time graphics generally have depth buffers with limited bit-depth, which puts a limit on the amount of details that can be rendered at a distance.

To avoid these problems, games often employ skyboxes. Traditionally, these are simple cubes with up to six different textures placed on the faces. By careful alignment, a viewer in the exact middle of the skybox will perceive the illusion of a real 3D world around it, made up of those six faces.

As a viewer moves through a 3D scene, it is common for the skybox to remain stationary with respect to the viewer. This technique creates the illusion that objects in the skybox are infinitely far away, since they do not exhibit any parallax motion, whereas 3D objects closer to the viewer do appear to move. This is often a good approximation of reality, where distant objects such as clouds, stars and even mountains appear to be stationary when the viewpoint is displaced by relatively small distances. However, designers must be careful about which objects they include in a fixed skybox. If an object of known size (e.g. a car) is included in the texture, and is large enough for the viewer to perceive it as close by, the lack of parallax motion may be perceived as unrealistic or confusing.

The source of a skybox can be any form of texture, including photographs, hand-drawn images, or pre-rendered 3D geometry. Usually, these textures are created and aligned in 6 directions, with viewing angles of 90 degrees (which covers up the 6 faces of the cube).

Simple texture-based skyboxes had severe disadvantages. They could not be animated, and all objects would appear equally distant at infinity. They looked simple and because of certain limits, it was hard for designers to be creative with this feature. But starting in the late 1990s, some game designers built small amounts of 3D geometry to appear in the skybox to create a better illusion of depth, in addition to a traditional skybox for objects very far away. This constructed skybox was placed in an unreachable location, typically outside the bounds of the playable portion of the level, to prevent players from touching the skybox.

In older versions of this technology, such as the ones presented in the game Unreal, this was limited to movements in the sky, such as the movements of clouds. Elements could be changed from level to level, such as the positions of stellar objects, or the color of the sky, giving the illusion of the gradual change from day to night. The skybox in this game would still appear to be infinitely far away, as the skybox, although containing 3D geometry, did not move the viewing point along with the player movement through the level.

Newer engines, such as the Source engine, continue on this idea, allowing the skybox to move along with the player, although at a different speed. Because depth is perceived on the compared movement of objects, making the skybox move slower than the level causes the skybox to appear far away, but not infinitely so. It is also possible, but not required, to include 3D geometry which will surround the accessible playing environment, such as unreachable buildings or mountains. They are designed and modeled at a smaller scale, typically 1/16th, then rendered by the engine to appear much larger. This results in fewer CPU requirements than if they were rendered in full size. The effect is referred to as a "3D skybox".

In the game Half-Life 2, this effect was extensively used in showing The Citadel, a huge structure in the center of City 17. In the closing chapters of the game, the player travels through the city towards the Citadel, the skybox effect making it grow larger and larger progressively with the player movement, completely appearing to be a part of the level. As the player reaches the base of the Citadel, it is broken into two pieces. A small lower section is a part of the main map, while the upper section is in the 3D skybox. The two sections are seamlessly blended together to appear as a single structure.

I know the fundamentals of python but I am an absolute beginner to panda3D. I have read different things on the internet to no success and now I am completely clueless on where to even begin with creating a skybox.

A skybox is 100% something you can accomplish. Effectively to create a skybox we want a 3d cube with a texture on each face there are lots of premade ones but you can also make one pretty easily. Once we have a 3d model creating one in Panda3D is simple.

I am searching for a better skybox solution also. i spent 12 hours cooking a lightmap only to have 72fps when looking down with the headset on the OVR metric tool only to have it drop to 30 when looking up past waist level. I'm pushing 90fps in the unity editor. Looking back at my other builds I bet this situation made me ditch a few projects because its not something to you readily think of once the xr rig starts stuttering. Looking for a solution for this.

Would it work if the skybox textures are actually mapped onto a room-size box near the view point, instead of being applied to the scene background or some extremely large box? In this way the motion of camera will lead to a noticeable parallax.

The Drei library has a simple to use Environment component that can project the environment HDR onto a plane inside a sphere. Use the ground attribute to adjust radius, height & scale. It looks quite good with little effort.

I want my interior to look just like this scene!

this scene is also developed in Unity, But it seems skybox is not affecting the interior at all.

I am using Realtime GI. and since this is only for testing, I am not planning to use any light baking method.

It seems that Y-axis is the default vertical axis for sky box hdri images. Is there a way to rotate the skybox images so that for example Z-axis is the vertical one? Or do I have transform my models into the skybox coordinate system?

Skyboxes are rendered around the whole scene in order to give the impression of complex scenery at the horizon. Internally skyboxes are rendered after all opaque objects; and the mesh used to render them is either a box with six textures, or a tessellated sphere.

Adding the Skybox Component to a Camera is useful if you want to override the default Skybox. E.g. You might have a split screen game using two Cameras, and want the Second camera to use a different Skybox. To add a Skybox Component to a Camera, click to highlight the Camera and go to Component->Rendering->Skybox.
