Can you tell how much time you are modeling in Zbrush or do you have a script that saves even Ztool time?
I don’t understand what you are asking.
I’m sorry, my English is getting better Example: Suppose I took 2 hours to finalize a model, do you have a way of knowing this time by Zbrush?
I don’t think so. The history state doesn’t have a timer, so AFAIK the only way to keep track of your working time is to manually make notes of it.
I found this, but I do not know if it is good and I do not know how to use it.
You could set frequent quicksaves which will be timestamped.
