Hi Rokas, I'm trying to use random X & Y sizes using this method, but the problem it's on the Mapping.
I'm using 15 different maps and as you can see in the attachments, the texture it's not moving and it's showing the end of the tile, using randon offset with UVW Xform it's not an option using this textures, what I want to achieve It's something similar to Floor Generator, where the mapping it's moving to the center and scaling with the largest segment size.
The only solution I've found it's having a seamless map in order to use a random offset value or Use different segments with it's own mapping, is there a solution to have only 1 segment with the random size values using the same mapping?
Another user sent me a solution conecting the u Fixed size in the UVWXform with the X size of the segment with an arithmetic expression, but I cannot control the maximum X size.
Im attaching both files, the one where im exploring the solution and the solution from the user.
