Is it possibole to make globe.clippingPlanes more than one ClippingPlaneCollection,I want to clip more than one hole

Currently globe.clippingPlanes can only set one ClippingPlaneCollection ， Which files should I modify?

We’ve actually recently been working on supporting this! So it may be coming out in the next few months.

This is where the clipping plane shader code is added for the Globe:

CesiumGS/cesium/blob/54acd32f50c332605615a7b37b774c04690ef55c/Source/Scene/GlobeSurfaceShaderSet.js#L180


if (!defined(shadersByFlags)) {
    shadersByFlags = this._shadersByTexturesFlags[numberOfDayTextures] = [];
}


surfaceShader = shadersByFlags[flags];
if (!defined(surfaceShader) || surfaceShader.material !== this.material || surfaceShader.clippingShaderState !== currentClippingShaderState) {
    // Cache miss - we've never seen this combination of numberOfDayTextures and flags before.
    var vs = this.baseVertexShaderSource.clone();
    var fs = this.baseFragmentShaderSource.clone();


    if (currentClippingShaderState !== 0) {
        fs.sources.unshift(getClippingFunction(clippingPlanes, frameState.context)); // Need to go before GlobeFS
    }


    vs.defines.push(quantizationDefine, vertexLogDepthDefine);
    fs.defines.push('TEXTURE_UNITS ' + numberOfDayTextures, cartographicLimitRectangleDefine, imageryCutoutDefine);


    if (applyBrightness) {
        fs.defines.push('APPLY_BRIGHTNESS');
    }
    if (applyContrast) {
