Blender suddenly close itself

[Indra_DG]

my blender suddenly close itself recently, is that because of too much vertices / tris?, what is the max tris that blender allows?
in my viewport, i'm currently have over 300k vertices & almost 500k tris

laptop spec : rtx2060, ryzen 7, ram 2x8GB

Might be the ram, 8gb is not alot if you're going to use creative programs. I have been finding myself running out of ram on 16bs of ram.

[Indra_DG]

my ram is 16GB, 2X8GB

[Indra_DG]

also i don't think RAM is the issue, my blender crashed in normal viewport, not in render mode

[Deathscare]

You're gonna have to look into what is causing the crash because 500k tris should not crash a ryzen 7 with 16gbs of ram. I have your cpu too and i have had scenes of 4 million polys that didn't crash unless i moved too many dense objects.

Its new version problem, you can see that before crash Blender disconnect some vertexes and move them to the random position.

I've had models with over a _million_ verts in Blender 2.5 through 2.92 (this is common when sculpting or creating STLs for 3D printing) so 300K verts is not the problem.

As for the crash, what were you doing with the model when it crashed, (ie working the model, applying modifiers, rendering, sculpting, posing, animating, baking animations or textures, creating or using a particle system, were you using an add-on, etc),

then there's what engine were you using, Cycles, Eevee, Workbench).
Each engine has its own instabilities that can cause a crash.

You say you have a RTX2060 (lucky you, I'm still trying to get my hands on a new card since October to replace my RX580),

If using Cycles, how do you have that set up in preferences, (None, CUDA, Optix or OpenCL) and finally In the render Propetries ( CPU, GPU Compute).

Blender has always had crashing issues and we use to cheer and wipe our brows if we got through a project without it crashing. In fact, we used to consider crashing as a feature, not a problem,

Th point of this is that Blender is a vast program and any number of things can spike a crash. But most of the times it crashed, it would be because of something the user was doing or an add on failure, not blender itself.

The real solution here is to turn on and spike up your autosave timings in Preferences - Save& Load - Autosave so that if Blender does crash, you can recover the last autosave and only be a few steps backwards from when it crashed. I currently have mine set to 2 minute intervals for autosave, if working a complex thing, I'll turn that down to 1 minute intervals and it has been a life saver, many times over.

I've spent around 150 hours in blender, suddenly start crashing since the last 2 days, the crash itself varies, mostly when i'm in edit mode (i can't sculpt yet) like when alligning & extruding vert to add detail on my model, today it crash when the program idle & i was AFK for several minutes when i come back the program was already closed.

I only use 1 additional add on i think its "import wrangler" or something.

I used Cycle most of the time, never crashed when rendering, at least for now.

Yes fortunately use auto save, but still annoying as heck when i was so focused editing my model then suddenly it crash with no reason

Yes it happens to me once when i save my model in certain pose, then the next time i load it, one of the object was not in correct position, totally different from the last time

I mean that Blender just disconnect part of model and crashed, he dont saved it :)

No, this happened before the crashing issue, i saved & load the same exact file, 1 part of the model was completely in different position & i never pose it in that position before

[Pte Jack]

The model may be loading into it rest position and might spring to the pose if you move the playhead. Have you set key frames properly?

Or, you accidentally save a key frame and it was the active action when you saved the project and the model is loading using that error pose.

Check your Dope Sheet and change it to the Action editor, is there an active action and what is it? Check the FCurve editor, is there something weird there that needs fixing?

I already delete all keyframe, that's not the issue anymore, but the crashes is, & still occurs randomly

[Indra_DG]

WTH it crash again just now when i switch to wireframe view while in edit mode

It is also possible that your hdd is in its last days.

HDD ≠ random crashes in Blender.
