background color removal from hatch

[DaM marson]

Good morning.
I press that it's my first post on the forum and I'm still on the top of my arms, but I'm in front of a problem that I haven't found a solution looking online, and that's making me waste a lot of time.

I am working on quite "confusionary" bases (although I would like to use some other term to define them) where there are numerous samplings, some of which also present the color background.
the problem is that these background fields are divided into several layers, containing elements that I intend to represent. some of them are in nested blocks and besides the color background is always set in true color, making useless the possible use of a ctb.
for now I have tried to manually select the samples and remove the background color; However, given the high number, this takes me a long time.

I wondered if there was a lisp that gave a selection, it allows to set in "none" the color background of all fields, if possible also of nested blocks. the other properties of the samplings would instead remain unchanged.
I use autocad lt 2024 (English).

Thank you.

Did you search online? Maybe there is. .

Unfortunately I have found nothing so specific, neither between the lisp of leemac nor on the various forums..
if someone finds something I kindly ask to share it.
Thank you.

@dam marson the lisp script that was published in this post sul theswamp, funziona anche con ac2024 lt

perfect, I tried and it works.
I leave it below for convenience, with the name of the nobackhatch function.
Thank you.

placing at 0 the variable "fillmode" and making a "rigen", turn off all the retinals.

Obviously, not a lisp, it works on all versions ... also of lt.
