Thanks again for your answer and the help you have provided once again.
I’m afraid it cannot be a problem with the mapper as it is set before this function is called ( I can check that easily because I use an other function that does exactly what I want to do in terms of rotating and translating an actor before I call this one ).
One of the weird things is that the matrix is apparently modified because I have tried to send it through UDP to an other machine to check if that was working and apparently it is working (the matrix I receive is modified it’s just that the rendering cannot be done for some unknown reason).
Again, thanks for the help you have provided me so far, you have been more than helpful.
Contact me when you’re back and I could send you the whole project if you’d like to take a better look at it (however be aware that I’m still playing with vtk for android, so the code is not optimised at all but that is not the point for the time being).
Have a very nice holiday with your family (wish we had the equivalent of Thanksgiving in France).
Best / Cordialement,

> The shaders look fine so I suspect what is happening is that somehow a render is getting called when there is no data for the mapper. The "error setting attribute" type problems stem from either the shader not actually using the passed attribute or attempting to set the attribute with no data. Looking at the shader the attributes are definitely being used which means the error is maybe due to somehow setting the attribute with no data. Maybe somehow the mapper is not setup yet when your new method is getting called? I'm out for Thanksgiving the rest of the week but if you are still stuck next week let me know and I can look a bit deeper.
