The env variable doesn't help. I see such errors: With subloading enabled i see this: before Glyph::subload(): detected OpenGL error: invalid enumerant Glyph::subload(): texture sub-image width and/or height of 0, ignoring operation. I've posted the log on the github issue. Remo

Hi Robert I've tested the latest branch on MacOSX 10.11.6: https://github.com/openscenegraph/OpenSceneGraph/commit/f1f6d23eebda16a9d4560a0a130580d65edf7401 Non of the stock samples works because of not applied shader. MacOSX needs a default shader. But simple text works when i add a shader on

Re: [osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

Hi Remo, As a first step to resolving the osgText issues with VAO I have created a text_refactor branch off OSG master. All I have done so far is add the ability of osgText::TextBase to have NodeList _children that it traverses automatically, this _children list is intended for the Text and

Re: [osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

Hi (Robert :) I've tried a lot of things to get osgText working on MacOSX with VAO. GL3 on OSX Core Profile requires VAOs. osgText doesn't setup the VAO path correctly on MacOSX. I can show glyphs when I use a osg::Geometry as a Wrapper to draw geometries from text glyphs like so: Code:

Re: [osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

Hi Remo Hi Sebastian I'm wondering if you have a running osgText on MacOSX Core Profile. Your shader-code is not compatible with it. I've written a partial working version of this shader. I also found that the Glyph Texture is created with red. But i think something is wrong with the

Re: [osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

Hi Sebastian Thank you for your help. Yes i don't see the glyphs. I use osgEarth, but this should not be a problem :) I've tried the following according your sample: Code: ControlCanvas* canvas = ControlCanvas::getOrCreate( view );

Re: [osg-users] bug: osgText doesn't work on MacOSX GL4.x with VAO

Hi Remo, A more detailed description on how it fails would be helpful. If you're seeing non-textures quads instead of your glyphs you need to adapt your shader as the text-rendering isn't using a normal blending. I've attached my default core-profile shader which uses pre-multiplied alpha.
