How to fracture bricks for sim?

[tryhard_3d]

Hey guys long time lurker first time poster.

So I have a brick wall created in Houdini and I wanna blow it up. Got my texture projected and everything. The wall consists of several rectangular boxes all made in Houdini. Projection done in Maya. So now I wanna know the best way to fracture the bricks while still getting that interior detail on the "inside" faces of the bricks.

Moreover, once fractured, how do I apply texture on the inside pieces? I know we gotta separate the inside and the outside groups first and then apply the material accordingly. However, when I apply the material (with a broken brick texture), on the inside group, it just renders a single flat color (the color dominant in the texture) .

UV unwrapping the inside group and then applying a texture also doesn't work (renders out a single flat color). Maybe I'm doing something wrong Idk.

So what is the best and most efficient way to fracture bricks and texture the inside groups? Would love it if you'll could share some tips to help me out. Thanks!!

 

EDIT- I tried using Redshift. Thought that would be important to share.

Did you check the UV View (Space+5 in the Viewer)? Depending on your scale you might need to decrease the spacing on the UV Unwrap by a lot. Anyways, heres a file:
