Hi Davide,

I'm not sure what the problem is, but I suspect it could have something to do with the font loading code. Maybe the plugin does not find the file?

I suggest that you isolate the problem by commenting out most of the code and incrementally uncommenting it until you find where the ...

Ciao Davide,

I think the problem is that OF uses GL_TEXTURE_RECTANGLE by default, so texture coordinates are mapped to the image size ( eg. [0...512] for a 512x512 pixel texture ) as opposed to the typical [0..1] range with GL_TEXTURE_2D.

By writing the texture back to an ofImage you creating a ...

Hi Arnebert,

the problem is that these plugins are already present in the Avenue/plugins/vfx folder, this creates the crash you get.

glCopyTexSubImage( ... )

I usually call glEnable( GL_TEXTURE_2D ) also when using shaders...
but it seems like it is really not necessary, found this link maybe it can be useful
http://www.opengl.org/wiki/GLSL_:_common_mistakes
perhaps you are not calling glEnable before creating the texture?

Hi,
It should be enough to copy the .bundle file into the plugins/vfx folder
