Hey Stephomi, I think the crashing might be somehow linked to multi resolution, loaded my scene up this morning, used ‘reverse’ to rebuild my subdivision levels, did a bit of sculpting then as I was saving it crashed. When I loaded again, redoing sculpt without rebuilding subdivs the save worked
Hope that helps your investigation, let me know if you want me to send you the file 
What was your level when you saved?
When it saves it only saves the highest level.
No need for the file, I won’t be able to open it anyway, I only have the iPad Air 4. Not enough memory.
It was at the highest level, I just hadn’t tapped on reverse in topology menu to activate the lower subdivisions
It’s not multiresolution then.
Since I don’t have any other reports of crashes on lower poly model, my guess is it’s again a memory issue.
And without any reproducible scenario I can’t pinpoint the issue (Just having one success and one fail is not enough, if it’s 100% crash scenario it changes everything though)
@Steve did you try to export / import to new fresh scene?
Just worth a try.
Also in different formats.
Did you try other sculpts with same amount of poly and sub divs, or even more as your iPad has much more?
Just to exclude if it‘s an issue in general or just with this particular sculpt.
Only some ideas. Good luck.
I’ve since retopo’d through zbrush and reduced it to 9mill with 5 subdiv levels, so it’s a fresh file and I have an obj & ztl back up.
As Steph has closed the case as memory issue (even though I was only using a quarter of what was available) I’m not going to test any further. Maybe it was just something funky in the file…
I just want to enjoy sculpting a serene dragon at the end of my usual work day, I don’t want this to become a beta testing project. I’ll just keep an eye on file size and keep versioning cuz i want to do the rest of the body so it’s going to get much bigger… think I might do it in sections ( head, body, legs, wings) rather than a single enormous mesh
Or go with decimation, if necessary. Like Sinis did with his tea dragon in pre memory boost days. The detail of your lovely dragon you show on your screenshot, would work with much less resolution so far - till you want to bring in fine skin details. Sporkfumaster is a genius in doing details with a tenth of polys other would need.
But sure, you haven’t paid a fortune for your iPad to make compromises, if not necessary. And yes, you just wanna have fun.
But I‘ve heard from others working with 30 million polys with your specs, so one can‘t keep this thread alive as it says „keeps crashing ever since last update“
It‘s a unique problem, likely with just with this special scene.
Good plan, 20% decimation in Zbrush got it down to 1.8mill but not ideal for continued sculpting so definitely leave that till last once sculpting is finished (ha, when is a sculpt ever finished!)
Hi Stephomi,
I’ve been experiencing the crash of Nomad 1.65 while processing my work for a while now. My device is iPad Pro 12.9 inches. Just designed a simple character, however I might have done something wrong with it because I’m just a beginner. As fas as I know it maybe runs out of RAM because the character has overused polygons and vertices. Am I right?.
Not sure it’s related or not, this is what I’ve done. I sometimes coloured the model whilst sculpting. Using Gizmo too many times to adjust the model’s size. Too much orbiting or rotating the model around to find a good angle. Using Alpha too much (Alpha over an Alpha) - the patterns copied from Google.
Are these things related to the overuse of memory in a scene?
Also I read someone’s comment said decimation helps reducing the number of polygons. Will it much affect to my work, will it make the model distort if I use it?
Sorry for many queries. I’m really fascinated with the program and want to learn more about it, but really need a help for solution. Thank you so much
You are right.
Check the stats on the top left and use the topology tool to use less polygons, see Topology | Nomad
Hi Steve,
I’ve been experiencing the program crashing many times during my process.
Could you please answer to my question? I’m so curious about this.
It appears that your art work is really more delicate than mine and you used only 15.4M vertices. But, mine’s showing 22.9M on just a simple character-much less detailed than yours. I’m so surprised!
I show you here.
Do you think it’s because of the complicated colours or patterns that I put? Honestly I have no idea and that makes my project keeps crashing and can’t be complete.
Hey Ronin, as Stephane has said, the mesh you have for your character is way too high, I have double the ram that you have available and I still encountered problems with crashing. You also have to bear in mind that the save process also uses ram and if it is all being used up keep the model open Nomad will crash.
I’d say you could very easily bring your poly count down to 1million and it’d still retain the smooth detail. Hope that helps
I’ll try. Thank you so much
Version 1.84 crashing when i use TRIM
