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,
