hello, i'm trying to follow along with this tutorial on mapping a brick material to a brick wall: https://www.itoosoft.com/tutorials/uvw-xform
i'm running into an issue where when i type in the # of bricks from the texture map, 18 bricks wide by 54 bricks high, i get what looks like 5.5 bricks wide mapping on each brick (see attached image)
i do use real-world scale in 3ds max 2020, but i have real world mapping turned off on this material and real world mapping turned off on the original brick object.
thanks!

Hi.
I`m not good with mapping in Max and I`m not sure this will work but try to select the brick model and apply UVM Map modifier>>Box>>Uncheck Real-World Map Size>>Fit
-
that did it. nice. i didn't think the uvw map on the brick model would affect the railclone, not sure why i thought that. but it does and it fits great now. thanks for the idea!
-
ugh. so now it looks like i'm stuck at another phase of that tutorial :(
i'm by-passing the option to have controls for offset and scale because i want the grout of the brick to be included from the texture map.
i've entered in two expressions: "Input1/2" and "Input1*2"
however each of those expressions are giving me an error about something expected after the 2.
PS - added a new zip file of the scene
thanks

I don't have Max at the moment but since those tutorials are done in some previous RC versions you are probably missing "Return":
https://docs.itoosoft.com/railclone/style-editor/operators#:~:text=RailClone%203%20included%20a%20new%20expressions%20engine.%20Be%20aware%20that%20there%20are%20a%20couple%20of%20key%20changes%20to%20remember.
To send a value to the arithmetic node's output you must add a return command, for example:
return degToRad(90);
The new version uses a double == for conditional tests
The way you write numbers is now important, for example in RailClone 3:
1 = an integer
1.0 = a float
This means that in RailClone 3 the expressions:
return 1/2;
Will result in 0, because both values are integers.
To return a float value you would use:
Return 1.0/2.0;

thanks. i looked at it and tried a few different ; and such but still getting the error. the value that goes into it is an integer. there's a DVIDE U and DIVIDE V. they both have a constant set as FLOAT. the DIVIDE U and DIVIDE V have "# of Tiles on V" and "# of Tiles on U" which are both Integers. if i change those to Floats, i still get the same error.

Hi. You need return keyword in the start.
Test expression "-1*(Input/4)" in v2 should be written in v3 and v4 like this:
return -1*(Input/4);
Basically all expressions should have "return" in start of "expression" and You should end them with ";"
Feel free to check documentation (https://docs.itoosoft.com/railclone/style-editor/operators#Operators-ExpressionsSyntax)for more examples and explanations. Or just ask here and we will try to help out.
-
oh i see. ha. ok thanks.
-
ok wow. so my expression is now: return (Input1/2); and it says there's an error, however it displays no further information and it appears to work just fine! so maybe i've got something else glitchy and it throws the error but still works. and by working, i mean the UVW changes to match the object. in my case the offset of the bricks and bricks in the map.

If arithmetic node output is not connected you will get an error message. Don`t worry about that ;)
