Bug in Material of the official "ParticleEffects" Demo


the Material “M_Cave_Ground_Mud” in the official ParticleEffects Map don’t work anymore.
The problem is the “TransformVector” Node Error: “input must be a vector (Local501: float) or a scalar (if source is Tangent)”

I am sure Alan Willard need only 3 Second to fix it but how can i fix it?


Hi TheBasti82 -

This is a known issue and is currently being fixed internally but the fix for it is actually quite simple.

Connected this node will clear the issue and make the material render in the level without issue.

Thank You
