So this is something that has been happening since first time I’ve used Nomad months ago and it’s always present. I believe this is NOT a Nomad Bug, but an iPad “safety” measure. Let me explain.
When I’m sculpting specially high poly stuff, my iPad screen suddenly dims and things get darker. The iPad brightness setting is not changing and I already have played with all imaginable settings you guys can imagine (like auto-brightness) to see if this was not a setting but it’s not.
After searching for a while I found someone saying that actually the iPad have a security setting in place which automatically dims the screen if it gets TOO HOT. That was interesting because indeed I’ve noticed that this happens every time I’m working with high poly like I said and the iPad is kinda hot to touch. I’m using iPad Pro from 2019 btw.
Has anyone here experienced this or is aware of a potential fix for this issue? Is this something that only early Gen of iPads suffer from?
I only experience this while using Nomad btw.
Please let me know if you guys have any suggestions. I could make a video showcasing the issue if that helps.
Let’s not forget iPad doesn’t have fans… Reducing screen brightness is one way to cool it down.
Then it’s reducing the cpu clock speed, and then shutting it down (I guess… maybe it simply kill the app).
I also have the same issue on the same iPad. I knew that it was a heat issue though as I live in the tropics area of Australia. I have had several heat warnings appear on the iPad when I’m using it to take notes whilst in full sun on a construction site. It helps to take it off the folio keyboard to let it radiate the heat better.
Also, I’ve had the iPad fully shut down after getting too hot but never shut down in Nomad
Thank you Stéphane! Yes definitely not a Nomad Bug, I just thought I could get some tips by posting it here.
What I’ve noticed is that it basically happens every time, with lower res and post process off too. The difference is how fast it happens. For simple projects like that it takes around one hour or so of use to start happening. If things are pumped (like post process on and high res meshes) then it happens in 5 min or so.
Once it happens, the usually iPad tries to “recover” and sometimes brightness gets back up but just for a few seconds and goes back to low again shortly after that.
I wonder if this happens in the newer iPads too? I would definitely be happy to invest on one if it doesn’t, just for our beloved Nomad
That’s a very interesting point to know. I didn’t realize ipads had this feature.
On this subject,
I’ve actually made it a point to not use Nomad while being plugged in to charge. I’ve definitely noticed my ipad getting pretty warm on higher res models just by itself…So I just play it safe.
I’m sure it’s fine to do, but in my mind all that extra heat can’t be good for the longevity of the internals. It’s just too expensive of a device for me to replace
It was quite a shock to me as I was doing a building survey, making drawings / taking measurements etc and in full sun, approx 35 degrees. Suddenly there was a caution triangle on the screen and the message said “ipad has overheated, cool down to continue”. I had to put it into an ice-box where I was keeping my lunch & leave it for half an hour before it would work again!!!
Hmmm, I always thought this happens because of brightness regulation due to ambient light…even though I switched this function off
Happens in any app here, time by time.
Hello everyone . Unfortunately, I also suffer from this problem since I switched to an iPad Pro 2022 M2 -11 inch
And it really sucks. So far I have been working on the nomad on the Android Note Ulta device. And there it works perfectly without crashing almost at all and of course there are the problems with screen lighting that I experience on the newest iPad Pro. Please, if anyone here knows a practical solution to the problem, please share it with us
Are people really sculpting with everything turned on? I work in matcap mode 99% of the time, only turn on postprocess and full rendering for final renders. I can sculpt like this for quite a while on my various ipads.
I’ve seen cooling systems around, but meh… to me you have to accept the pros and cons of tablets, one of those is they have no active cooling, so you do what you can to not kick the system over into emergency cooldown mode.
More incentive to get the desktop version when it arrives to run on laptops and desktop with active fans.
When I have sunlight in the room and my hand covers the camera, are brightness regulation starts from iPad itself.
Other than that, working on highest settings is unnecessary and a waste of energy. Basic settings like multiplication on 1 and 50 max gives decent results, even for finding render presets.
Everything else is a waste of energy and heat, your work won’t get any better.
Working just in matcaps increases FPS significantly, less comp operation needed. Only switching post process on gives already a decent fps drop.
Sure, the better the device, the less FPS drop, but still lots of GPU / CPU action turned into heat.
You can check by yourself under debug/log/options/performance.
So first check your settings, switch off unnecessary stuff, check ambient settings. When issue consist it is worth to go deeper into it imho. But I doubt.
There are a few reasons why your iPhone brightness might be switching to auto mode even when it’s disabled while you watch videos. Here are some things you can try to fix it:- 1. Disable Auto-Brightness Completely:- Double-check that auto-brightness is actually off. Go to Settings > Accessibility > Display & Text Size and make sure the toggle for “Auto-Brightness” is switched off. 2. Turn off Attention Aware Features:- This feature uses the TrueDepth camera to detect if you’re looking at your phone and adjusts the screen brightness accordingly. Navigate to Settings > Accessibility > Face ID & Attention, and disable the toggle for “Attention Aware Features.” 3. Check Accessibility Settings for Video:- There might be an accessibility setting specifically for videos. Although less common, it’s worth checking. Go to Settings > Accessibility and see if there’s a section for “Video” and if any settings there might be affecting brightness. 4. Turn off True Tone and Night Shift:- These features adjust the screen’s color temperature to match the ambient light. While unlikely, they could be interfering with brightness settings. Go to Settings > Display & Brightness and toggle off both “True Tone” and “Night Shift”.
