VT Problems

[maxim]

I'm currently working with VT textures and found some problems arising:

First there are stripes when glueing my DDS Tiles. There was any solution about that anywhere in the forum but I couldn't find it.

Secondly, when zooming in, my VTs become more and more blurry before snapping to the next resolution level. That looks ugly compared to a standart hires texture. It's not so obvious with 'real' views, but on my technical textures (these projects gonna introduce a 16k topograpic earth and a 32k geologic earth) it's disturbing me. Does this effect mean that celestia is enlarging the current level until the next one fits exactly in, instead other way round (using a shrinked version until it reached it's original size, then use a shrinked one of the next level)?

Thanks for help and comments,

Can you be more specific? What kind of stripes?

Try reducing (divide by 2) the "TileSize" in your .ctx-file, this should improve the quality. But note that this will require much more memory, so people with low-spec systems will have some problems with this.

Sorry. I meant small lines along the tiles edges with slightly increased luminosity. Maybe some kind of interpolation problem for DDS compression.

Yeah, that's a simple workaround I also thought about. But I don't think that could be a long term solution.

I got the same problem with my JPG Earth VT.Strange white lines around the edge of some of the tiles,but the lines extended along the edge of a few tiles together,and were definitely not on the texture.I dont know what caused this,but when I remade the tiles using progressive JPG's instead of optimized it didnt seem to happen thankfully,cheers Jestr

Ok, I've got it.

The stripes where a result of a buggy (or at least quite weird) Photoshop function. Using the marquee tool and tranforming it to a smaller size caused it on subsequent usage.
