I am re-posting here just in case: Physical Material on Landscapes Not Working - World Creation - Unreal Engine Forums
When I place a material with a Physical Material on a landscape, the Physical Material no longer works. If I take that same material and apply it to a static mesh, the Physics Material works.
To make sure it wasn’t a problem with my Physical Material, I loaded up the Generic Shooter kit and applied the default materials from the kit to the landscape and I got the same results. Applying my material to the static meshes in that kit resulted in my material working as expected.
I have spoken to Allar and we have both concluded that this seems like an engine bug as neither Allar or I can see anything in the code that excludes landscapes.
I basically reproduced it like the above question.
I have a blank project, add a new landscape, added a new material, assigned a physical material to the landscape and did a ray trace. It never returns my physical material.
It does work on static meshes as expected … so I am very confused now.
I am hoping somebody maybe has a suggestion or an idea for me.
