Hi people, Now I know this questions has been posted before but due to the search not working I am unable to find it and so I must ask the question myself. If I have a mesh and I want to add a new subset to it what do I need to do? I have read much about this and it seems only the Optimise function can create a new attribute buffer. The problem I have is extending it. If I lock it add data and then unlock it will that work? How will it know the buffer is longer? I know the details held in the mesh and in a attribute table, So a quick explanation of what works will be fine. Thanks.
