Transparent objects and distance

by Demolishun · in Artist Corner · 12/09/2005 (2:24 pm) · 6 replies

I have noticed something very odd about transparent objects when viewed at a distance. I created some laser/plasma blast objects using 4 polygons and a transparent texture. When viewed greate than a certain distance it would go to some other redering mode so that you can see what the faces look like instead of using the transparent texture. Is this some sort of depth view or emap thing? This will not do for projectile blasts at all. It looks really crappy.

Here are couple of screenshots:

Thanks,
Frank

    I can't really see what your are trying to illustrate in those screen shots, can you post a higher rez version?

    My guess is that you are having a Mipping issue.

    Texture mipping is what is causing this.

    Your alpha channel is getting mipped and results in the whole object it is mapped to becoming at least partially visible.

    Make more dead (transparent) transparent space in your textures alpha channel.

    Todd,
    See how on the second shot you can see the plasma bolts close up look really bright and the ones further out look washed out?
    Also notice on the right side toward the middle of the shot you can actually see the bolt going from washed out to red hot. This is the problem I am referring to.

    Joseph,
    I will check the link out.

    So I guess this is not an exporter issue? I was hoping there was some LOD setting or mip setting I could change it.

    Thanks,
    Frank
