Failed to compile ./node_modules/@splinetool/loader/build/SplineLoader.js Attempted import error: 'mergeBufferGeometries' is not exported from 'three/examples/jsm/utils/BufferGeometryUtils.js' (imported as 'pI'). This error occurred during the build process and can only be dismissed by fixing the error.
i think maybe its just mergeGeometries ?
