Assigning material property to primitive object

Development Rendering
1

So I have been trying to create a curved walkway geometry in TM using its populate→place→spacing feature and I successfully added a primitive object to the spline. The problem I am facing is with assigning materials.

For some reasons, the primitive geometry (plane white) which is added to the path is not receiving any material assignment through drag and drop. I also cannot find an option in the place→spacing sub options.

Has anyone faced a similar problem and got any resolution?

Also is there any other way to create such curved road geometry in TM?
Thanks

I have found you need to apply the material to a primitive like a box and then once that shows up in the material menu you can place it on the primitive with replace material option. Its another convoluted process in 2025.2 which in my opinion is so full of bugs it’s a disaster.
