I've got a voxel model that I've imported from MagicaVoxel. It's approx 126x40x40 voxels. I've used "Upscale x2" to make it bigger. Cubik hung for a while then slowly started drawing a few parts of the model. I've now got approximately 20% of my model showing, the rest isn't there. If I then convert voxels to elements, I can see my whole model (though I'm not sure if the model is resized after converting it to elements.) Cubik is sitting constantly on 33% CPU/4GB RAM in use while still in voxel mode ~3 minutes after telling it to resize the model.
