When rendering the model using the npm package **gaussian-splat-renderer-for-lam**

I see the bottom part of model generated has cloud like blurred border. Any option to remove it?

Is it being added when generating LAM model.zip file or while rendering the model in UI using above library?

Please help me understanding and fixing this. I dont want blurred base in model.
