Should perspective be on if I plan to 3D print?

ZBrush Usage Questions
#1

I am creating a zbrush sculpture with the intention of 3D printing it. What are the best angle and perspective settings? Should perspective be on or off? If anyone has any advise about 3D printing from zbrush in general it would be greatly appreciated.

You almost always want to have perspective turned on. I prefer a FOV of around 60, but that’s a personal setting. Adjust that until you find one you like.

Thanks for your answer. I appreciate it.

There was another thread on another forum where one of the members was asking the same question. I believe one person was told to NOT have perspective on by a 3D print company. Something about it screwing up the proportions. As far as working with perspective on, that just comes down to personal choice. IMO it has always cause more problems to work with it on. So I only use it for rendering.

I would turn off perspective when working in the side/front/top views (depending on what you’re printing), and turn it on for anything else.

I almost exclusively do 3d prints. The perspective angle can vary greatly as it’s mostly based on the actual size of your model. Due to this for 3d printing I much prefer to work with it turned off. Sometimes I’ll turn it on here and there but I haven’t found a good angle to really work with it on.

I should also clarify that I deal a lot with scan data. This makes perspective less useful for my workflow than it may be for others.

Hummmmm, I am still confused. I am sculpting human figures with detail. When I have it on my face (facing directly toward me )
looks well proportioned, but when I turn it off it looks very wide. Is it flattening it , or is that a more realistic view? I’m hoping to work this out in words and not in multiple prints. Thank you all for your info.

Having perspective off is pretty unnatural. The widest part of a head is towards the back of the skull. Little to no perspective and it starts to make the face look wider and flatter, while too much can cause its own extreme (similar to http://www.dailymail.co.uk/sciencetech/article-2059455/The-camera-DOES-lie-Proof-lens-difference-pretty-pretty-ugly.html). Try to find the goldilocks zone that works best for you (and if you have access to the printer’s software, try to use it for the final previews of what to expect).

Thanks I’ll give it a try. I’ll post if I get a clear answer out of the 3D manufacturer I plan to use.
