Thanks, this is a regression accidentally introduced in a recent build. Will be fixed in v0.16099.

Thanks for your time.
Now it works fine.

But, there is one very minor problem.
Bellow line code still does not work in cloth binded shape..

tf.SetUVW (sInx, 0, uvw);  // but other channels is working well.

My English is not very good. The sentences may not be smooth
so please understand me.  Thank you very much.
