Mesh particle(use local space) with world position offset (local space to world space) is not working properly

[Anonymous_d7d94bfc69cf82975b38cef412cffdbb (제이워커)]

“use local space” optioned mesh particle with world position offset (local space to world space) material is not working properly in 4.25. (confirmed working in 4.21)

This means static mesh morph target node is not working properly too.

Here is the material nodes and particle system, etc.

• material nodes

• static mesh (wire and solid)

• particle system

I made these with both 4.21 and 4.25 and they shows different behavior.

UE4 4.25 mesh particle problem comparison with 4.21

I wonder there is another way to use mesh particle transform with world position offset material in local space…

Thanks!

for the test, here is content file.
simply unzip in content folder named “Bug_report” in 4.25

and unzip in content folder named “Bug_report_4_21” in 4.21

I’m having a similar issue.
It looks like it’s using World Position not Local Position for materials when applied to particles.
This might explain what’s going on for you too.
