It seems I forgot to add [USE_TISSUE_TEMPLATE:HOOF:HOOF_TEMPLATE]. That has been corrected. It should work now then.
Their vanilla population number is curretly [POPULATION_NUMBER:15:30] so Im buessing that means 15-30 per biome. Will the [UBIQUITOUS] tag make them too frequent or have any negative effects besides simply ensuring that they will certainly appear wherever they can appear?
Once again, many thanks.
