How to eliminate bumps, elevations so 3d model is flat?

So how to do elimination of bumps, elevations in 3d model, no ups and down, I’m looking for designing solution or tool
or make vertices with y=0 ?

Hi @grzesiekmq,

Normally you would do this as part of your modelling pipeline, otherwise you are adding some unnecessary overhead in your app.

If you are determined in solving this in the Playcanvas side your best bet is a vertex shader, where you change the Y coordinate for all vertices to 0.
