Hi All
I've been using osgText on GLES1 with some good results, I'm now moving to
gles2 and am having some issues. I've attached a basic shader to get things
started which looks like the following
"uniform sampler2D diffuseTexture;\n"
"varying mediump vec2 texCoord0;\n"
"void main(void) {\n"
" gl_FragColor = texture2D(diffuseTexture, texCoord0).aaaa;\n"
"}\n"
This has worked in the past on windows and i've seen it mentioned in this
post
http://forum.openscenegraph.org/viewtopic.php?t=5340
However on GLES 2 I'm getting just solid white quads at the location of
each texture quad. I've found this in my log output
>>

The width and height look to be 18 and 22 to me, does anyone know what the
issue might be.
Cheers
