Detailed textures missing on Duna and Moho

[zaruthoj]

The textures are missing in the flight scene view when in low orbit on Duna and Moho.  Both planets look normal in map view and from high orbit.  All other planets render normally.  On Duna, everything looks normal until 110km.  Then, between 110km and 100km the texture fades out and I'm left with the view seen below.  Screenshots:

I originally encountered this in my modded career mode game.  However, I replicated it at Duna on a fresh, unmodded install in an sandbox game.  The Duna screenshot comes from that game.  The Moho screenshot comes from my modded install.  I checked all other planets and moons with hyper edit on my modded install and they were all fine.

Setup Details:

Linux 64 bit.  Build ID = 01028.  Edge highlighting is disabled because otherwise I can't see the inside of the VAB.

Hi @zaruthoj, it looks like you have "Biomes visible in map" enabled in the debug menu, it's rightshift+F12 on Linux, so check that first.

The second pic looks like something else though, maybe unrelated.

There's a few log errors, if you're on Steam I suggest you try verifying the cache, it might help.

Thanks for the quick reply!

I agree, this does look like the "Biomes visible in map" setting.  However, this is what it looks like both with and without that setting enabled.  I do think that what I'm seeing is the biomes though.  The colors are different than the Shift F12 setting, but the outlines are roughly the same.

I'm running without Steam.

 

I've also tried:

Running at lower resolution (1360x768).

Disabling HiDPI mode (in Linux).

Toggling every setting on the in-game settings menu.

Changing Duna's minDistance setting in settings.cfg

 

None of these affected the issue in any way except for changing texture quality.  When I changed texture quality the outlines of the garish colors shifted around a bit.

Okay it's weird that it's only doing it to Duna and Moho, has it ever worked or has it always looked this way for you? 

As it's a new install we should be able to rule out a bad file, unless both installs came from the same zip folder, it is possible you have a corrupted zip.

It could be a weird rendering bug that only appears with those two planets and only with your mesa driver and intel card combination, if that is the case then a driver update might fix it, I see you're using 14.04 LTS and it uses quite an old version of the mesa driver, updating should make newer drivers available, as would using the Edgers repository which supports 14.04, your current driver looks to be 10.1.3 while edgers has 11.0.4

It may also be caused by anti-aliasing, which the Unity engine has a lot of trouble with on Linux, some things will fail to work with anti-aliasing off even if anti-aliasing itself doesn't work, if it's off try with it on and vice versa.

I also notice you don't have a lot of video ram, only 256 megs according to the Player.log, I can't see your graphics card memory in the hardinfo report, so maybe it's shared with the system.

There's a nullreference exception in the Player.log as well but it looks like it's related to the UI, rather than the terrain rendering.

I'd try anti-aliasing first, then a fresh zip if it wasn't already, then look at a graphics driver update, hopefully that will fix it.

If it really is because of insufficient video ram I'm not sure what you could do, I think some old laptops allowed you to set the shared memory in the bios so that may be worth a look.

The biome theory might not be a good one.   I just discovered that Moho is not pure white.  It looks like this:

That dark band looks nothing like Moho's biomes.

That screenshot was taken at 105km, so it also shows the fade out of the texture.  As I said before, at 110km the texture opacity is 100%, and at 100km it's 0%.

This issue has always been present for me.

I tried the following, all with no effect:

• Changing anti-aliasing settings.
• Used a fresh zip.
• Switched over to 512 Mb of video ram in BIOS.

I attempted to update my graphics drivers, but this is a work laptop and they don't allow adding external PPAs.

How about running a linux distro from a memory stick or an external HDD ?  You could update that without affecting the works laptop.
