The gltf file I obtained after using ClippingPlanes to cut the geometry does not have a cutting effect, but rather a complete geometry? How can I save the true cut effect?
How did you obtain the gltf file? Via GLTFExporter?
Might be helpful if you could post your code in a glitch or a codepen?
Here’s a glitch template you can use…
Hit that, “remix” it… and put your code in near the bottom of “script.js” then “share->code” the code and paste the link in here.
