Blender 2.81 render crash
I've recently tried to render some animation in Blender while using the VisualSPHysics add-on and I've found that Blender crash doing so.
From what I gathered on other forums, it can be because of the interactions between blender and the add-on, especially something related to time-out probems when loading the render window. I'm not sure if it's a Blender or VisualSPHysics bug...
For people who still want to use it and render animation, the workaound I've found is to render the animation as multiple images (.jpeg, .png,...) via script. To ensure that the correct mesh is loaded for each frame, I used a time delay.
Here is the script I used:
for step in range(264,444): # change to the frames you want
time.sleep(10) # time delay to ensure that the propoer mesh is loaded (10s maybe overkill)
bpy.data.scenes["Scene"].render.filepath='D:/............/image_%d.png' % step #write the adress of your export folder
