How to multiply `material.opacityNode`, not replace it?

@muzammil12345 yeah true, but the above is a simple example. I need to port the code in this thread,

How to port vMapUv to TSL?

Ok the conditional check probably does work. I verified the way to handle/discard pixels for opacityNode in this thread, basically this works: material.opacityNode = Fn(() => { const alphaFactor = float(0.2) const newOpacity = materialOpacity.mul(alphaFactor) // this works (hard coded 0.2 causes mesh to not be visible) If(newOpacity.lessThanEqual(0.3), () => Discard() ) return newOpacity })() Now if I update to try to get th…

that uses vMapUv with WebGLRenderer to TSL with WebGPURenderer to run logic per fragment/pixel.
