Decal Material node Transform (World to Local) no longer works in 4.12+

When using the Deferred Decal Material Domain
using a World to Local Transform produces an error , however it used to work in earlier versions (4.10)

[SM5] (Node Transform) This transformation is only supported in the ‘Surface’ material domain

we are using the transformation twice , once on the absolute position , and another on the camera position to implement interior mapping on decals. we have tried using some of the other options within Absolute World positions (camera relative etc) but none have produced the same as the World to local transformation.

is there a new method of producing those vectors in the Decal material domain?
and why was it changed to no longer work as before?

Hi, did you ever figure this out? I’m trying to do the same thing in 4.15.

Thanks!

Bump, still the same in 4.16.

Might have to do the transform directly in the material :confused:
