Thank you.

As you say, when I change the last entry, the color changes.
In this case, the change affect all area.

However, I want to change the part which I want.

I wonder that I must set 0.1, 0.2 etc. as volume data.
I tried it, but all area changed.

Any advice is helpful to me.



Best Regards,

Yukihiro Miyashita
