Hi, @ppcuni

Sorry for the delay in getting back to you.

We have confirmed that the content of this correction is correct and that it works correctly, and we would like to incorporate it into the product.

We would like to ask for additional confirmation or correction of the following points.

• Regarding the modification of CubismRenderController, there is a place where backing field _renderers is called as it is, so please use the property Renderers unless there is a special reason.
• Please move the variable between the backing field _renderers and the property Renderers, since it is defined there.
