Hello, and welcome to the forum! :)
For performance considerations within the Voxel Editor I am planning to stick with the 32x32 limitations for now, but it is definitely something I'd like to revisit to see if there's a better way to optimize and maintain the large number of voxels simultaneously (increasing to 64x64x96 would increase the possible simultaneous voxels from ~50k to around ~400k) . Of course the models would be fine once they are saved since they are converted into meshes, so the main concern would be optimizing the Voxel Editor itself to handle that many. I would like to look further into the possibility, but it will be further down the road since it will most likely involve a redesign of the editor.
Thanks for the feedback and for your support! I hope you have a great day, also.
