Hello,
I tried the following code:

from ursina import *
app = Ursina()
window.title = "ursina"
skybox_image = load_texture("sky_sunset.jpg")
Sky(texture=skybox_image)
app.run()

expecte to see:

but I get:

terminal output:

how can I do it better and where is the fault?

Looks like that GLSL version isn't supported by you hardware, so it didn't compile. I lowered it to version 130, so update and try again: pip3 install https://github.com/pokepetter/ursina/archive/master.zip --upgrade. You're likely to run into issues with other shaders too, and there might not be a fix for that.

Also, the sky image doesn't actually loop horizontally, but that's my bad :P

Hi Petter,
thanks for reply. I have tried to follow your instructions and get the following terminal output.
nothing has changed when testing the script.
(as you can see I even have problems formatting my posts correctly, sorry for that)

terminal output of pip3 install ... :

Oh, that's right, you're on linux. do pip3 install git+https://github.com/pokepetter/ursina.git then. This is covered in the installation guide by the way.

some other more sophisticated sample codes work quite well. Could it be that the size of the images or window/screen need to be adjusted to each other?

Petter,
maybe I should reinstall everything again.
Tomorrow I will try again.

Hi Petter,
does the ursina code at the very top work for you?
I also have problems with other 3D graphs on my computer.
e.g. Geogebra 3D "Surface(x,y) = sin( x^2 - y^2)".
The screen flickers and is unusable.
Maybe too weak graphic devices or wrong setup.
...
In the meantime i tried it on another computer with different hardware. 3D rendering works here, but the ursina code does not work either and shows the same result

Yes it works for me.
I'm confused when you say 3d rendering works on the second computer when the result you posted is an issue with the 3d rendering.
If only the default shader is working, try setting the shader to None. The Sky is supposed to ignore shadows and fog, but if you don use them, you can use the default shader.

Petter,
I am sorry if the statement was unclear.
On PC1 there are problems with e.g. Geogebra 3D and Ursina, on PC2 the rendering generally works e.g. Geogebra 3D but also not Ursina. So I thought it is not because of the hardware.

Yes it works for me.

which Ursina version ?

try setting the shader to None.

OK, I'm trying to figure out how to do this.

Entity(model='cube', shader=None)

and since Sky is an Entity:
Sky(shader=None)

the window opens briefly and then it collapses along with the output below.
I think I give up. It took me too much time to get used to it.
Thanks anyway for your effort.
code:

from ursina import *
from ursina import shader

app = Ursina()
window.title = "ursina"
skybox_image = load_texture("sky_sunset.jpg")
Sky(texture=skybox_image, shader="None")
app.run()

Compare your code to mine, it's not the same

Yes, sorry:

from ursina import *
app = Ursina()
window.title = "ursina"
skybox_image = load_texture("sky_sunset.jpg")
Sky(texture=skybox_image, shader=None)
app.run()

but nothing has changed. The rendering looks the same as at the beginning.

I'm really sorry, but I don't remember the details. At the time I spoke to a developer and he couldn't help either.
Do you have the same problem?
If you can solve it please drop me a short message.
I thought after a year there were enough updates and users who had the same problem and it was solved. So maybe it's not Ursina (?)
I use Kubuntu 20.0.4

a2cy Jun 24, 2022

I've used Kubuntu and I had no problems but as petter said the texture doesn't display properly because it doesn't loop and has the wrong dimensions.

wallygit Jun 25, 2022
Author

what are the correct dimensions and how to make it looping ?

a2cy Jun 25, 2022

you need to edit the texture file

a2cy Jun 30, 2022

petter updated the texture should work now

I think the main issue is that you assume it's wrong when it's in fact supposed to look like that. Keep in mind the texture on Sky will cover the whole sky, not just the area you see currently. If you for example rotate the camera, you'll see that it makes sense. The texture doesn't loop properly, but that's a different issue.

yeah you are right I actually solved my issue by changing entity model to cube.

This seems like a very smart thought to me and makes sense.

I've found a solution. You need to use a skybox image (just get one from google). (JPG format is preferred)
