1096460 - WebGL demo using bones fails with "too many uniforms". Shader doesn't compile

Status: RESOLVED WORKSFORME

(Core :: Graphics: CanvasWebGL, defect, P3)

Description

[David Rousset]

User Agent: Mozilla/5.0 (Windows NT 6.4; WOW64; Trident/7.0; Touch; .NET4.0E; .NET4.0C; .NET CLR 3.5.30729; .NET CLR 2.0.50727; .NET CLR 3.0.30729; Tablet PC 2.0; InfoPath.3; rv:11.0) like Gecko

Steps to reproduce:

1 - Navigate to http://www.babylonjs.com/index.html?DANCEMOVES with FX (any version)
2 - It stays on the loading screen with "Streaming items..." whereas it loads a dancing girl in IE11/Chrome/Opera


Actual results:

Open F12/Firebug, you'll see that logged:

"BJS - [19:08:31]: Unable to compile effect: default" babylon.js:3:5987

"BJS - [19:08:31]: Defines: #define DIFFUSE

#define LIGHT0
#define POINTDIRLIGHT0
#define UV1
#define BONES
#define BonesPerMesh 66


Expected results:

The WebGL scene should display an animated bones mesh. 

There are 66 bones which is not supported by some mobile platforms but it works on IE11 & Chrome desktop versions. The shader should compile on Firefox on desktops.

This WFM on Firefox on OS X. You're testing on Windows 10, AIUI? Can you post the graphics section from about:support ? Does this work if you use Firefox's safe mode? ( https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode )

When you say "all versions", I'm assuming you've tried all of release (33.1), beta (34), dev edition (35) and nightly (36) ? If not, can you try nightly? ( https://nightly.mozilla.org/ )

Could you provide the graphics part of about:support for this machine, please? Does it work in Firefox's safe mode? (see comment #1)

Tentatively moving to webgl...

Same error on safe mode.

Confirmed in 36.0a1 (2014-11-17) Win 7 x64

Firefox asks ANGLE how many vertex uniforms you can have.
ANGLE says 254.
You create a shader that asks for 264 uniforms in one variable.
ANGLE checks the shader and ANGLE says "No".

I've reproduced the same message "BJS - [17:46:19]: Error: ERROR: too many uniforms" in Google Chrome Version 39.0.2171.71 m

More information on why the limit may be lower than expected, can be found in this thread: https://code.google.com/p/angleproject/issues/detail?id=401

Just tested again in Chrome 41.0.2236.0 dev-m (64 bit) on Windows 10 Technical Preview and it works. 

Wondering if the problem doesn't come from ANGLE on Mac OS or Linux mapping to Open GL.
