some issues on particle_system_effects_Godot3
Didifred opened this issue · comments
First thanks a lot to share these cool particule effects !
I've experiment some crashes without so much error log eitheir in editor clicking on cube_o ,cube and demo_p nodes or running the appli with "Socket close .. " error message. => So i suppress this nodes, and it's OK.
My GPU is quite old ... NV GeForce GT 630M, but i tried on more recent hw with NV Quatro and still some of the previous nodes crash the execution. What could be the issues ? Is it openGL drivers that are buggy ? How work ES 3.0 emulation on PC based on standard OpenGL, is it included in Godot ?
just checked... no crashes at all(in Linux)
my Godot version is Godot 3.2.2 stable and Godot 3.2.4 beta4
I tested this project on Nvidia 750 and Vega8 integrated (both 2Gb VRAM) no crashes...
il check tomorrow on Windows

thanks but... I warn you that every project I made here is just a "weird test-experiment"(that I use for my own learning graphic stuff) with some problems that you have to fix... (I did not know ways to make it correct at a time making these projects or I misunderstand something...)(as an example in this particle_system_effects_Godot3 I send camera position as my own uniform...when it should not be like this)... also code in projects is not good for "understanding/learning" but this is not tutorials - it up to you if you want to spend your time understanding my code...
I'm on Windows too. No problem at all for me, i just feel to give you feedback can ne useful for you.
I think it dépends on the background knowledge, in my case i know gles 3.0 ans GLSL shaders, but not particules techniques. Since i have a Godot game in progress, it give somme ideas for effect.

wait I dont understand,

is not this project particle_system_effects_Godot3 crash in editor for you?
does it work outside of editor? https://danilw.itch.io/particle-effects-godot3 from exe or web-version?
what you Godot version?

Sorry for the confusion, when i say 'no problem at all' it was relative to your warnings relative what you qualify as sandbox tests.

what you Godot version?
So yes it is particle_system_effects_Godot3 that crash on the editor and fails to execute in exe version.
I use 3.2.3 stable and test as well on 3.2.2 stable.
I tested on Windows Nvidia 750 drivers version 456.71
everything work
(also before releasing I tested it on multiple PC and receive feedback from other people-it works for them also)
I can guess your crash may come because of "too much Vram usage"... particle_system_effects_Godot3 in the Godot editor use 800Mb Vram, and exe or web version use more than 600Mb
and fails to execute in exe version.
I 100% sure that shaders there is correct(I report more than 5 driver bugs writing those shaders(lots of time wasted on debug drivers), so I literally 100% sure about it I did dodge every driver bug), and Godot GLES3 render are fine.
can you say what console output(browser console(F12)) you have launching web version https://danilw.itch.io/particle-effects-godot3 on page? if it crashes on web it 99% problem in your GPU or drivers, it still may be problem in Godot render
And can you please try launching this https://danilw.itch.io/cubes-experiment (in web or exe) this is even more complex shaders and scene but in GLES2(Godot GLES2 mode), does it work for you?
Making invisible the demo_p/cube node make it works.
so i make a little test simplyfying the fragment shader of "particle_cube_base.shader" with a constant fragment, no more crash.
So i conclude it is a gpu driver bug :
NVIDIA Quadro K1100M/PCIe/SSE
Version pilote 341.49.
25/02/2015
341.49
its very old driver, I know it "technically" supported because its old generation of GPU (and it close source driver...)
but I do not have the hardware to test my shaders there
so I do not know about this old driver problems sorry :(

easy way to test - you can try to make empty godot project, add 3dmesh instanse make quad, make shader material and copy paste this code to shader there particle_lineGlow_base.shader
and look if it crashes
The particle lineGlow_base.shader works Ok, addionnally i replace code of particle_cube_base.shader file by the particle_lineGlow_base code, and like expected no more crash.
I close this issue since issues are related to Nvidia drivers.
Thanks
okey thanks for report, il add note about this problem on old drivers
you can ask me anything about my projects in discord if you need https://discord.gg/JKyqWgt
