UE4 - Wonky results from multiplying world displacement

NeonPenguin

Hi everyone,

I'm trying to get the hang of World Displacement with the idea of then animating the strength of the displacement along with some panners (probably) to create a bubbling surface material.

I've currently got a very simple material set up to make sure the basic World Displacement is working correctly before I start creating more detailed maps & adding movement, but I'm noticing some slightly weird results from multiplying the displacement map - the more I multiply, the more it seems to lean towards the positive in X & Y.

Does anyone know why this is happening (it sort of makes sense from a mathematical perspective...) and how I can workaround it?

Thanks!

You need to multiply by the "vertex normal world space" so it will go based on your vertex normals. Then you can put your "amount" multiplier after that.

Ahh I see.

Yep, that solves it! Thanks
