This caused the cracking problem.

I need to fix the cracks in the wall.
Basic maker removal
I learnt how to clone out the markers. Important to add an alpha to the paint strokers or roto around the maker.
I need an alpha to cut out the region I cloned.

to remove the lamp
using by Keymix node
I learned how to extract the grain
first technique

second technique with 2 different alternatives
I learned that denoise plate minus original gives me the noise.
This time to add grain only to the patch . I can merge the noise over the patch to rematch noise.
