Sky Box Question

edited December 1969 in Daz Studio Discussion

So I've only been at this a few weeks. I just got the easy environments outback set which I think is great. Anyway I tried using my own photos in the skybox and it looks fantastic except in the final render I'm getting a line where the corner of the box is. I've tried everything I can think of to get rid of it, but I'm stumped. Any help would be appreciated.

    Could it be your lighting?
    Ambient occlusion?
    Did you do something to Flipmode's surface settings apart from exchanging Flipmodes jpgs with yours?

    Hi jasonreed7, I just stumbled over your thread.
    That line most likely happens on the edges of the sky cube, and it might be tricky to get rid of it.
    Without going into detail, it has to do with 1pixel repetition, which can vary even due to texture scale.

    I don`t know how you got your photo to fit with the skybox UV`s, but I`d guess you somehow cut it into square pieces.
    You could try to fix the line with a minimal UV Tiles offset in Daz Studio (like +/- 0.01) but I am not certain if that would work.
    The other option is fixing it in Photoshop or whatever you use, by adding or removing one pixel from the selection you crop.
    It can be quite annoying to find the perfect spot though. :/

    Sometimes texture seams can be blended just by upping the Max Raytrace value is DS, remember folks Max Ray goes down from 1 to .5 .3 .2 ect for UP in quality. That trick works on elite textures, not sure it will on the skybox but it might.

    I also when Hand Texturing extend my textures at least 1 pixel over the templates on all sides, that allows the seams to blend most times and hides the seams properly.

    Lowering your shading rate will greatly reduce the amount of visible creases when using skyboxes and skydomes. I recommend using a rate of 0.1, but even 0.4 should be sufficient enough to reduce most, if not all of the creases.

    Well, if it is a case of lines on skydomes ...
    Getting rid of lines / wireframe / mesh of skydomes showing in renders

    1.
    Go to the Scene tab, select the skydome, click on the icon at the top right corner with lines and a small triangle to display a context menu, there should be an option ‘convert to sub-d’ (in the case of a skybox - not a skydome - that's probably not an option)

    2.
    The way I usually choose is to apply a shader that is capable of disabling “Ambient Occlusion” on the Sykdome surface, like e.g. uberSurface or uberSurface2.

    3.
    turn up the bias on the uber-environment light to get rid of the grid lines, I think it’s set at .1 by default, I put it up to around 1. or you can subdivide the mesh.

    Thanks for the advice. I'll try some of these out when I get a chance.
