Hi,
I have checked and tested the sources again now and the interpolation-time itself is correct, but the ''fading' process is very dynamic and not linearly because of the moving start point and the moving target point, so they can converge quicker than the actual fading time...
I've tried finding a formula for correcting that non-linearity but haven't found a good working one yet, either it starts too quick or too slow...
Best regards,
Klaus
