Hi all, we have a problem with the OpenSG Blendchunk implementation. We are trying to render a geometry that has blend equation set to FUNC_ADD. The graphic chip is either onBoard Intel or ATI. It seems that GL extension glBlendEquationEXT is not supported by these chips. OpenSG throws a warning that indicates that the extension is not supported. However I'm not sure if this extension is necessary when using FUNC_ADD. Please find attached a test geometry..
