Maybe a stupid question, but i wanted to proceed sculpting on my shark. As i want to try out stuf i have 3 of them currently (seperate objects). For some reason there is one that doenst like to be sculpted anymore: nothing happens when selecting it and try to sculpt something. If i select another shark object, it works perfectly. Did i accidently lock something and where to unlock or what else could this be?
Or, if you can still select it and it has the sculpt knife icon in the Outliner, maybe it is Masked and the Mask is hidden. Try CTRL+M to toggle visibility of the Mask.
