GPU/driver lacks sufficient vertex uniform vectors for QuadShader.

[foobraco]

I just receive this error on the java backend after upgrading my game to a 1.5-SNAPSHOT, it was working fine with 1.4.

Is this error a result of my hardware, wich is kind of dated, or there was some change that could be triggering this?

It should fall back to the triangles-based shader in this case. It's just an informative message.

[samskivert]

And it means what it says, the QuadShader needs the GPU to support a minimum number of "vertex uniform vectors" which your GPU (or driver) does not. It's not a big deal. The QuadShader is not that much better than the IndexedTrisShader.

[foobraco]

But it's not doing the fall back, when this message appears the game just hangs saying that

java] Exception in thread "pool-1-thread-3" java.lang.OutOfMemoryError: Java heap space

[samskivert]

That's unrelated.

foobraco same issue with me after upgrading to 1.5.1, wondering how u solved it finally

[foobraco]

@neerajnagi if it is about the Quadshader, Michael was right, it does a fallback so it is just a warning, the OutofMemoryError, it seems like it was part of our implementation on a tilemap of interactive background we had.

@foobraco but the application hangs ultimately with black screen. My use case is very simple where I am getting this error. I am just drawing an imagelayer, and thats it. And no one else is getting this error on playN group, I am really surprised.

[foobraco]

@neerajnagi but your problem is with the Quadshader or with the OutofMemoryError? If it is the first one, there is no much I can do to help you, is a GPU issue, and the second one, was resolved by another member of my team, but with your use case, you shouldn't be having memory issues.

[neerajnagi]

application is not responding and just hangs so its a memory issue.
