Hey TheOneWolf,
You should start with the Pack provided in the PKFXContentExamples project.
There are several reasons why Blast cannot be imported as-is in UE4:
- All Blast’s textures are dds, and UE cannot import compressed textures.
- All Blast’s particle renderers have a blending mode AlphaBlend_Additive (also called pre-multipled alpha), which is not implemented in UE4. That’s why we made this default UMaterial red. UE4/Class PopcornFXEffect - PopcornFX
- Blast has been edited in a PopcornFX Pack setuped with an AxisSystem Right Handed Y Up, so, some properties like the Gravity are incorrect if import the pkfx in a Game Engine that has an other Up axis, and UE4 is Left Handed Z Up. UE4/PK-Editor Pack Setup - PopcornFX
I will add a wiki Troubleshooting page with those issues.
