Scatter spline on spline does not work with spline mapper

Hi Substance team,

When using scatter spline on spline and trying to hook it up to a spline mapper grayscale afterwards, the spline mapper grayscale does not return any result and has no information in the UV output.

 


When not connected to scatter spline on spline, it shows the result as expected.

 

I have attached the sbs file for your testing.
Hope it helps with the troubleshooting and resolution!

Thank you!

    Hi Nicolas!

    Thank you! I didn't realised it was due to that. It works now!

    Hi!

    The Spline mapper has some limitations, it can only draw splines located in the main tile and the 8 surrounding tiles.
    It looks like you have set an offset in the Scatter spline on spline node that makes the generated splines to be located very far away from the main tile. That's why you can't see anything in the Spline mapper node.
