#2141 Random buildings not showing

With Lowspec renderer if Model shader is 1, random buildings disappear.
This happens specifically on Intel video.

On Next the problem is much different:

1. On Intel they disappear in Lowspec regardless of "Use Shaders" setting.
2. On NVIDIA they disappear only with "Use Shaders" on.

I forgot to add, that has been happening here for a very long time -- it is not caused by the latest changes.

I agree that it sounds like a driver issue. Have you looked to see if an updated Intel driver is available?

[Anonymous]

I have as recent Intel driver as Arch Linux has -- must be pretty recent. Still, another user is having the same issue on the mailing list, so it's pretty sure about Intel driver.

Hi Michael,

I have just fixed a couple of bugs in building.eff. Could you do a
quick re-test for me and let me know what the current problems are?

I don't expect them all to be solved, but I'm hopefull that some of
them may have been addressed.

With default renderer if Model shader is 1, random buildings disappear.
With ALS enabled, their light level is flickering at Model shader 0, at other setting they seem ok.

This happens regardless of OS, but may depend on Intel driver.

Unfortunately they still disappear as of -next.

[Stuart Buchanan]

So, does it work if model shader is set to 0? If so, it's likely that
your integrated graphics card simply doesn't have sufficient
attributes to handle the requirements of the model shader.

Yes, on level 0 they work, but have worked before.
All other models work with all shader levels, but not random buildings.

[Stuart Buchanan]

Hi Michael,

I made some further updates that reduced the number of attributes required. Could you re-test please.

Hi, Stuart,

They still don't show up, unfortunately -- sorryyyyy :'(

What kind of effect is applied to random buildings, I might try and hack it

I have a vague feeling it's trying to pick up either light map, normal map or some other texture slot which is missing, and then instead of showing something it doesn't want to show nothing at all

Kind regards,
Mike

[Stuart Buchanan]

That's a shame.

If you want to take a look, the effect is Effects/building.eff

Can you provide me with details of all your rendering options, so I can
double-check there's not some combination of settings I have broken? Are
you using Compositor?

Are there any errors in fgfs.log?

-Stuart

At least two people on Mac are reporting that random buildings are not working on 2020.1.1 and 2020.1.2. I will confirm if this is the same model shader problem or not shortly.

[Stuart Buchanan]

OK. Key thing to understand is what their rendering options are, in
particular the /sim/rendering/shader/model and
/sim/rendering/shader/quality-level, and if they see them if they drop the
quality level.

Confirmed, model shader setting to zero restores it.

One user uses an Intel HD 6000.
I don't see this on Windows 10 with a Nividia 920.

[legoboyvdlp]

Other user is on a ATI Raedon HD 5670.

[Stuart Buchanan]

I assume neither have any errors in the log files or on the screen?

This sounds like exactly the issue that merspeiler has been seeing. Are
they using the Compositor, and can you get a dump/screenshot of
/sim/rendering/shaders/

Thanks for helping out with the diagnosis on this.

If it's on Discord, please send me the link.

Sorry about the long delay, Stuart -- I had really thought I had replied, somehow.

Any Model shader level greater than zero, regardless of other shader settings.
Both Compositor and old pipeline are affected.
Far as I remember, ALS on/off did not fix it either.
No errors in fgfs.log.

That's a shame.

If you want to take a look, the effect is Effects/building.eff

[Stuart Buchanan]

Hi Michael,

You did provide all the details, thank-you!

Jonathan is reporting a very similar issue from elsewhere on the same ticket.

I'm going to do another code-read to see if I can track this down.

-Stuart

[legoboyvdlp]

Hi, neither has any error message of any sort. I've tagged both of them in #techsupport on the main server.

[Anonymous]

I've just checked with a NVIDIA card, and buildings don't disappear there. They disappear on the same computer if I use Intel graphics instead.

[Anonymous]

To make it more confusing, on next:

1. On Intel buildings never appear in lowspec but appear on ALS.
2. On NVIDIA they disappear with lowspec with "Use Shaders" checkbox turned off, which is strange because Model=1 in the old terms should correspond to having it on.

[Frederic Türpe]

i think I can reproduce this too but have to check.
