Opacity bug (alpha shadow issue)

Hi,

here again with this bug that seems silly but it's not...

it seems it's something related to the alpha shadow calculation as it's not well calculated when there are intersectios.
I will share the scene in next post.

It should not happen this...

thanks!
Javier

here previous max scene...

hope you can find a solution... as for a bird or grass or whaterver where you use opacity maps... this is needed to be rendered properly where the geo intersects (but the alpha channel not)...

thanks

Hi javierluisbravo,
in this case try to set the Ray epsilon (Kernel Panel) to 0,000001
