HQDOF not working

**niektb** · March 8, 2014

I noticed that the HQDOF shader is not working correctly:

ERROR: Failed to compile shader 'shaders/glsl/hqdof.fs': 0(69) : warning C7583: Initialization of uniform variables requires #version 120 or later 0(122) : warning C7011: implicit cast from "int" to "float" 0(207) : warning C7011: implicit cast from "int" to "float" 0(207) : warning C7011: implicit cast from "int" to "float" 0(221) : warning C7011: implicit cast from "int" to "float" 0(221) : warning C7011: implicit cast from "int" to "float" 0(221) : warning C7011: implicit cast from "int" to "float" 0(225) : warning C7011: implicit cast from "int" to "float" 0(231) : warning C7011: implicit cast from "int" to "float" 0(236) : warning C7011: implicit cast from "int" to "float" 0(236) : warning C7011: implicit cast from "int" to "float" 0(275) : warning C7011: implicit cast from "int" to "float" 0(276) : warning C7011: implicit cast from "int" to "float" 0(278) : warning C7011: implicit cast from "int" to "float" 0(279) : warning C7011: implicit cast from "int" to "float" 0(291) : warning C7011: implicit cast fr...

I'm running the latest NVidia drivers on both a GeForce 610M and a GTS450. (Windows 8 and Windows XP in sequence) Does someone have any thoughts on this?

Adding

#version 120

to the file gives another bunch of errors.

Confirmed.

**historic_bruno** · March 8, 2014

Hi, can one of you apply the following patch:

fix-hqdof-error.patch

and see if that fixes it?

Applied patch (after some finagling), got this error:

Thanks! It seems your drivers are very strict now. Here's an updated patch to test:

fix-hqdof-error.patch

gameboy · March 9, 2014

I want to know what is HQDOF? Thank you! :lol2: :stinker:

**historic_bruno** · March 9, 2014

There's a ticket for this bug but I never looked into it until now http://trac.wildfiregames.com/ticket/2111

I want to know what is HQDOF? Thank you!

High Quality Depth of Field, it's a post-processing effect that requires GLSL shaders. You can try it out in Atlas, on the environment tab under "Post effect", if you have all the fancy graphics settings enabled.

historic_bruno, My, friend! I have a GTX650 graphics card, I chose "Prefer GLSL" in the option, but when entering the game, the game crashes if I do not choose this option, start the game, the game does not crash. :unknw: :unknw: :unknw:

**niektb** · March 9, 2014

Found 2 more implicit casts at line 312 (in the latest WIP patch)

float weight = clamp(depthweight + sampleblur, 0, 1);

Should be:

float weight = clamp(depthweight + sampleblur, 0.0, 1.0);

Furthermore at line 302 it breaks at calling a non-function:

vec3 samplecoloradd = color(samplecoord,blur)*mix(1.0,float(i)/float(rings),bias);

Not sure how to fix this error.

Thanks for more testing It probably doesn't like that there's a local variable there called 'color' and also a function, maybe some shader compilers can handle that.

Does that option also set "gentangents=true"? As far as I know, that option is still required for preferglsl to work. http://trac.wildfiregames.com/wiki/Manual_Settings#AdvancedgraphicsGLSLonly

Is set in this file do?

**niektb** · March 10, 2014

Is set in this file do?
data\config\default.cfg

C:\Users\JohnDoe\AppData\Roaming\0ad\config

At that place you should create a local.cfg in which you paste the prefered lines.

Mine reads this:

REQUIRES gentangents=true.preferglsl = true; Generate tangents for normal and parallax mapping.

your latest patch crashes the game without warning.

That's odd, it worked locally (Radeon HD 6850 - Win 7/64). Do the logs contain any errors?

Sorry for the delay:

The signature from Windows 8:

Googling tells me that nvoglv32.dll is from NVidia, that explains why it doesn't happen with your AMD card.

The mainlog gives 3 warnings, not related to HQDOF though:

The interesting log is empty, no crashdump is created.

Yeah, at this point I need to know if anyone else gets the crash after applying the patch. Another thing that might help is to get the call stack when it crashes, using debugging techniques described here. IF it occurs in the shader program itself, that sounds like a driver bug, if it's in the game code, maybe the call stack will show something we can fix.

Alternatively, if someone knows a lot about GLSL shaders and can check my patch for mistakes, that would be good

With GDebugger the game freezes with this at screen:

Any chance that it's working correctly and your GC just can't handle it?

edit: mmh, seems unlikely for your 610M…

Edit2: I've uploaded a different patch, that fixes the issue for me and I wonder if the "#version 120" at the top could make a difference.

It happens too at a GTS450 so I think the GC isn't the problem indeed.

From what version should I apply the patch? (From Bruno's latest patch or the svn?)

Now, it doesn't crash but the errors are far from fixed. :scratch_one-s_head:

Log:

I found BTW a possible solution for the non-function error:

(In French)

The other errors seem to be related to the fact that different types of vars are being mixed.
