Well here's my method of making nice looking wooden interior floors.
You will need LWCAD at least version 4.5 though.
-First create strips (plank width) divided to required number and length of planks.
So one (connected) strip containing the number of planks you want in length direction
-Copy (lwcad vector clone) them to fill the room width
-Use LWCAD Jitter tool to make random seam offset (in length direction)
If you want you can use bevel to create a physical seam, or remove seam to create small gap between planks
-extrude to create thickness
-Now for the fun part, create a morph target and use Jitter tool to randomly move planks in X and Z direction
If desired you could use random (object) select and rotate a certain percentage of the planks 180 degrees.
-Now apply UV coordinates
-Return to base obejct and apply material, add textures and you have nice planks with non continuous wood pattern all the same texture size
- Now use lwcad surface random to apply randomly a specified number of surfaces, copy your surface across all versions and apply variations
To your liking you could even use the LWCAD Jitter to slightly move, scale, rotate each plank
