[tmp solution]Blender hangs

[tis]

Hi,

I just would like to report and share:
Rarely I try to do some simple thing in blender and sometimes I try more complicated things too.

It is unpredictable, but there are time periods like cases when blender hang after scale mesh on mga9.

Code: Select all

blender-3.3.8-1.mga9
python3-3.10.11-1.mga9

Linux localhost.localdomain 6.5.11-desktop-5.mga9 #1 SMP PREEMPT_DYNAMIC Sun Nov 19 01:09:14 UTC 2023 x86_64 GNU/Linux


I had similar problems on mga8 with blender2.8?? (it quited on rotation/zoom when edited mesh), but I've downloaded a newer versions source code (v2.9.1) and built with my hw/sw environment, and that works better, so I've done the same and I think blender 3.5.0 works better now. Since then harder to reproduce the fault in the current mga version. (I know my vga not the best for this, Intel HD630, e.g. slower than Nvidia but useable)

[tis]

Another error I realized with all blender version on mga9 (I've tried blender 4.0.1 release from there website too), that when I tried this displacement, the eevee render hangs on render 4096x4096 img and then the popup dialogs are faulty. (the first render may look well, but the second will render something transparent, and there are rubbish in dialogs, until close/restating blender)
With Full_HD resolution it works well!

I found in log that gpu hangs:

After render

I found a tmp solution to change timeout: https://devopsx.com/intel-gpu-hang/
so if i mod timeout to 10000 it creates the img well and no error and dialogs are perfect.
!!! the render will be very slow !!!! (maybe not because of the long time limit, because I haven't realized addition slowness yet)

Additional info, I can realize it with the current and the prev mesa/dri drivers.

I've closed this, as the recompile of blender solve the main problem. 'Till that it works well, I could make interesting things, like smoke:

Quick effect->smoke (modified settings+particle system) + displacement on cube - EEVEE render

I've tried the mageia packaged blender too, not so easy but after some modification on e.g. a cylinder it hangs usually on scale (move/rotate/zoom).

I think the mentioned second fault happens because I asked too much from this card, but can be solved with changing driver timeout.

If you check this render with smoke, you can realize the shadow on cube is at wrong place. Caused by displacement in cube material, but only with eevee render. (with blender 3.3.8mga, 3.5.0mybuild, 4.0.1blenderbuild too)

Fast I created this remembrance about smoke and cube...

Additional info:

If you don't increase the time limit, you can still get errors in log when edit objects in eevee viewport and it still hangs. I realized it with some displacement/bump in textures... So I can advice changing the rcs0 timeout...

I've downloaded the source of the latest blender v3.x (v3.6.5) and that also works well, I can use it for a while, but sometimes it also hangs with my VGA. I accept my card is slow and not enough for this type of projects... (sometimes the 10000 timeout is also not enough)

I have displacement/bump in every textures. This is the shader for snow:

I can say I can use it and if I save when I've finished a state I can continue... (have to restart+reload, works for hours or more time, depends on complexity)

[tis]

I could finish the scene today in blender 3.6.5. It is still working since more than 3 hours.

Happy Holidays!


I've just would like to try blender and tree-gen

I've created Snowman from 3 sphere, coals from flatten cylinders, nose from cone, hat from cylinder, arms with tree-gen.
Plane generated with ocean modifier on a plane.
Small pine trees generated with Sapling Tree Gen module.
Snow stain/balls generated with Real Snow module.

Cool
