Re: Mitaka Version 1.0 was released

Go to the original (untranslated) URL (i.e. http://4d2u.nao.ac.jp/html/program/mitaka), locate the download link (search for "1.0.1") and click the link. I suppose the translator breaks the link.

Re: 64K/128K Specular Map Blue Marble Next Generation VT PNG !

to compress dds files with nvdxt the format options -dxt1c, dxt3 or dxt5 is what is compressing them. dxt5 has the best compression i think. -u888 is no compression. dds will have larger file sizes than png but png files are rendered slower. If your trying to save diskspace the format to use would ...

Are you trying to get a smaller DXT3 file size? Lone Of course my aim is to minimize disk usage. Let me expand a bit on my problem of understanding. I assume that the switch -quick/-quality_normal/-quality_highest is used to turn on compression (correct me if I'm wrong). Then I would expect that wi...

Re: Update to virtualtex needed?

Hi Fridger, I'm addressing this to you specifically just to let you know I understand why you may be loathe to take on problems people may have with virtualtex and Cygwin. There are just so many variables--from user error to line ending issues to changes in Cygwin--that it would be a never ending p...

Re: 64K/128K Specular Map Blue Marble Next Generation VT PNG !

I have just a doubt: why dxt1 and not dxt3 or something else? I suggested DXT1 because the VTs have no alpha data (as Cartrite correctly surmised). But you are also right, there is a quality difference between DXT1 and DXT3/DXT5. It's particularly noticeable in flat ocean color areas at extreme zoo...
