No they shouldn't, they're still very useful for editing old voxels. There are (or were) a few voxel editors who are very good at drawing voxels using those programs.
Its just easier if you have practice.
Every day there are less VXL makers which use VxlEd, mainly because the game is getting older and releases should be faster.
(And no, actually you can easily pump out voxels with VxlEd. Thats what i use.)
Yeah... :rockbrow: Arent you supposed to be studying? Hva editting? Ugh..I wouldnt go that far. just extract say...BEAG.vxl and BEAG.hva. Edit\Re-Do the voxel, rename both file example= DEEZEL.vxl and DEEZEL.hva and then make the codes.
