Hi,
I’m getting really annoyed by a skybox I’m trying to make, cause whatever I do, my skybox keeps looking cubed (even though all edges have the same color, you still see corners, so that it looks like you’re inside a box). I set the wrap mode for all textures to Clamp, so that’s not the problem, but what is?
Texture compression? Try turning it off for skybox textures.
Naaahhh that’s not it.
Here, I’ll show you a screenshot:
Hope that helps.
Yeah I just had a test of this and compression makes no difference, however… setting the texture filter mode to ‘Point’ seems to sort it. Let us know if you have any luck with that.
Make sure that each of the 6 skybox textures has it’s wrap mode set to “clamp”.
I’m building a series of skyboxes right now. Your problem is not the mapping but the warping of the skybox texture. The corners are there because your textures are built so that they’ll work with cylindrical projection, not spherical.
I’ll post a small tutorial when I get done with this but essentially, you want to:
- put six cameras in your 3D package of choice
- build an environment to take a picture of
- Fire off the six cameras to capture your skybox textures.
I know that’s vague, but it’s late and I’m on deadline.
More later - promise.
:s.
This post basically sums up the problem and fix nicely. Providing the camera’s position never changes, and it’s FOV is 90 degrees, the results come out just right.
You can also “do it on the cheap” and use the pinch filter in Photoshop on each of the cubes images, but it’s difficult to get it perfect. Though in some cases it may be the only option.
Other’s suggestions to change the texture to clamp mode is also correct, as in it will fix any seams which appear.
