The ALS HUD shader and ALS-filters

An exciting "new" option in FlightGear, that includes reflections, lightmaps, the particle system etc.. A lot is yet to be discovered/implemented!

The ALS HUD shader and ALS-filters

Postby Necolatis » Sat Apr 15, 2017 10:27 pm

The shader looks really good, but I seem to have an issue with using ALS-filters at the same time.

Any help appreciated.

Here without ALS-filters:

Here with filters (normal and default):

The HUD has this material setting:

MATERIAL "hudMat" rgb 0.80 0.80 0.80 amb 0.00 0.00 0.00 emis 0.00 0.00 0.00 spec 0.00 0.00 0.00 shi 50 trans 0.10

Furthermore I have an material animation on it that turns emission to 1,1,1

This is the effect:

Code: Select all

Hm, works fine for the Shuttle HUD (that's pretty much my only test case) - and it's clearly affected since it loses color in the IR cam. In fact, it looks like your second shot in the IR cam...

So to confirm, the HUD loses color whenever you enable filters, regardless of what filter you run?

Yes, except in infrared vision it works fine though, it gets a white color.

I also tried just using the stock HUD effect, and it gives same result.

Well, if it works in the shuttle I must have done something wrong, I will try to find out what.

I have the same issue in the shuttle, when setting /sim/config/shuttle/hud-filter=1. Is there anything else I have to do?

I am using the latest $fgdata and also tried clearing $fghome.
Used the latest dev-branch shuttle (orbit).

Btw. Really liked the displays and looking at earth through a window.

I'll have a look again - I'm on my devel setup, maybe there's something set in a subtly different way to FGData.

Conceptually this should be harmless as it's just a color filter, but it could be that there's a parameter not properly declared.

I think I found it - subtle one... Please pull FGData and try again.
