DDS maximum resolution

Post by jhlk » Thu Jan 16, 2020 9:29 am

Is 4096x4096 really the maximum supported resolution for dds texture files?
With a resolution of 8192x8192 each file has a size of about 44MB which seems to be doable on decent hardware, or am I doing the math wrong?

8192 dds tiles are already used on several sceneries without problems. Their size can be 88MB with dxt3 format (for water alpha channel).

In that case the error must be on my side. I'll keep trying to get it to work.

It turned out to be a hardware limitation on my side.

This is a bit misleading, I think he was referring to the single DDS texture file, which cover a patch and not the entire tile, while you are talking about the entire tile texture resolution (which is broken down in patches sized dds file on the disk)

Yes, we have already sceneries with full 4096 dds tiles but the use of 8192 must be limited to some places, and it's better to avoid to much of them located in the same zone (around 45 km).

Just to confirm: sceneries where each dds tile is 8192 do work as well but require an accordingly specced pc.

That's really interesting, I know some scenery use 4096x4096 pixel DDS but when I try to create my own it get rendered as black water, it happened the same even with standard 2048 DDS file when I tried to use the latest version of the NVIDIA texture tool but I noticed the header was different with the new toll and I blamed that.

Yeah, I forgot about that :D
I had this issue as well but didn't have the time to investigate it further and went without including water in the textures.

I've seen that some had similar problems while creating water or automatically unpacking the scenery (which would be nice to know the reason, as files shouldn't be altered in any way) but I don't have water and it happen even if I compress the texture in DXT1a of which Condor should ignore the alpha channel entirely.
