Vector Displacement not working in Composite map

[Thejiminator]

Hi guys

I’m having issues combining a vector displacement map with a standard greyscale displacement map in a composite map

I want to use my vector displacement map as the base, and then paint tire tracks on top as a greyscale map, but the composite map just seems to ignore the base vector map

Does anyone know of a fix for this? Or is combining two types of disp maps just not possible in Max?

Thanks

Solved it with help of Marcin from the Corona team!

The solution is the mix your vector displacement map with your greyscale displacement map before you insert the vector displacement map into the vector displacement node (Material network attached)
