Invisibility texture and Double side texture.

[TiTiMartos]

Hi, it seems that there is a problem with the vision through an invisible texture, and in the upper room with double-sided textures.
In TRLE it works perfectly, in TE mode NGLE, they appear and disappear.
I upload some example images.

TRLE

TE-NGLE

and in TEN mode it does not work.

Can it be solved?
THANKS

!!Sorry, or is this a question for Tomb ENGINE?

Please share your project and texture file to investigate. This does not tell us a lot.
