Hi !

Does anyone know how to modify a landscape material instance parameters at runtime?

I want to turn my layers wet when rains.

Is that the correct way to do it ?

Edit: I manage to create a “Material Parameter Collection” and use that workflow to change the values. Is good that way ?

Thanks!

Hi there,

Yes, it is a good way to create “global parameters”, so all materials will be affected by the same parameter at run time. This is useful to create seasonal foliage changes and wet effects.

Material parameter collections are probably perfect for it.

However you can parametrize the material and change values (scalars) on the run via blueprint too.
MPC is just faster to set up.
