Grunge decal is not showing after turn on virtual texture

[JL_env (PigGames)]

Hi I’m using 5.2 preview version,

The grunge decal I placed on the wall is not showing after I turned on ‘enable virtual texture’. The other decal like graffiti is working however, I assumed it is comes from transparency issue. Since the graffiti and grunge decal’s difference is transparency.

I dig into several document but there’s no similar issue like mine.
I even checked the ‘material expression texture base’ and see if the sampler type is ‘virtual color’ and it is ‘virtual color’

Any idea how to fix this?

I found the solution! Seems grunge decal don’t support the VT texture,
so this should be converted the regular texture.

When ppl have similar problem like mine, it should be setup as “M_MS_Decal_VT” in your material instance.

But you should change the parent material here like this in the image.

Then it will solve the problem.
