Crash When I Paint

[Rikev]

OK program starts now, that's a good sign I guess?

But as soon as I start painting the tutorial model that appears the program freezes and stops responding. I did the registry key thing it tells you to do so I don't get why it is freezing? It sits in Task Manager on 0% CPU and 2GB RAM used (I have 16).

The program is completely unusable and unreliable. 😞

It seems to happen if I move the mouse anything but a slow crawl???

I've enclosed the log. It says it has a plugin called iray using nVidia but I don't have an nVidia card? I use AMD on the newest drivers.

I'm having the same issue as well.

Lets see if I can figure it out.

Already figured out a workaround for Sampler not installing. Now that i've had some sleep after being up for 30+ hours, now maybe I can try and help figure this out as well.

I don't believe the iRay errors are the problem, that's only for iRay rendering, saying since we don't have Cuda Cores it won't use them essentially and go back to handling it on the CPU instead of GPU.

Scanning down (my) log, lets see what all I can find.

[WARN] <Qt> QMetaProperty::read: Unable to handle unregistered datatype 'Alg::PaintData::Float3' for property 'Alg::ColorButton::value'

That's really all I can find in my log, it's the only warning, the only errors were the iRay stuff, but I mentioned above I don't think that's even the problem as it's going to CPU instead to handle iRay rendering.

For any Adobe people - I did submit a bug-report that contains my crashlogs and Crashpad whatever that is.

[N1warhead]

I found a temporary work around where it doesn't crash.

At the top right of viewports you'll see a couple camera icons. A bit to the left of that you'll see a pause icon. Click that and you can paint. Then click it again to see your updated paint strokes on the mesh.

[Rikev]

So I won't be able to see the paint appear as I add it?

[Rikev]

OK that works for me too, no crash if I press pause. Not a particularly usable way of working though! Does show where the issue may be.

[N1warhead]

Yeah not usable really haha.

But it does help isolate things I think.

I submitted a bug report earlier (you may want to as well).

Support got back with me rather soon.

They said to try downgrading drivers (I don't know how to downgrade AMD GFX drivers), so perhaps you can try that. They said they had a similar issue like this a few months ago. I guess certain driver versions could potentially do this. But no idea on that front. Never had issues when it was substance launcher and using SP, SD, Alchemist.

We have several users reporting stability issues on AMD GPUs with the latest update, we are currently investigation the problem.

[N1warhead]

Please try to keep us updated to any news on the matter.

[N1warhead]

Any updates on the matter?

[Rahul005 · Accepted solution]

you can go within the installation folder and rename the .exe "Substance Painter", this should solve all issues you are having 🙂

I tried it and after that My painter stop crashing... It's works for me... You can try it too.

[N1warhead]

Wow I legitimately thought you were trolling us so I never even attempted it. When they marked it as correct I couldn't believe it so I tried it. Wow, this is totally nuts and actually fixes it.

This worked for me too, so still not fixed as of Jun 2022.

Which AMD drivers version do you use ?

This is a bug in AMD GPU drivers that should have been solved already. See: https://substance3d.adobe.com/documentation/spdoc/gpu-drivers-compatibility-205362107.html
