Hi, In EXT_texture_rg.txt it is mentioned of GL_RED_EXT on gles 2.0.
In glformats.c::_mesa_es_error_check_format_and_type returns GL_INVALID_VALUE if GL_RED_EXT(as it reaches default case) so glTexImage2D(..., GL_RED_EXT, GL_UNSIGNED_BYTE, data) fails. Though GL_EXTENSIONS contains GL_EXT_texture_rg. So it seems that GL_RED_EXT is actually only possible with gles >= 3.0. What am I missing ? Thx in advance for any clarification. Julien
