Has anybody else experienced this issue? I'm rendering an animation out of Blender 2.82.7 with RPR. This first three to five frames go well but than Blender crashes. I can then go on with rendering the frame it originally crashed on until it crashes again three frames after.
sorry for not clarifying this. I'm on RPR 2.35 which i downloaded from the thread you posted.
I can't send the particular project but just tried it out with the default cube which leads to the same error (project file attached).
Only things I changed from a default new Blender project:
- Frame export format to "OpenEXR"
- Changed path where the rendered frames will be stored to
- Keyframed a simple camera movement.

Re: Animation render crashes every max. 5 frames
Hi! could you share the scene (if it possible) and system specs? And also, please, recheck this with the latest beta release Beta builds for Radeon ProRender Blender (Q2) <https://community.amd.com/docs/DOC-2431>

Just an update: it seems to be related to the dual GPU setup.
When posting my system specs I thought it would be worth a try only to render with one GPU. Rendering is not finished yet but currently it rendered the 10th frame without crashing. So something seems to be different then
I have the animation crash with some specific scenes and with Medium Quality settings. Do you use a particle system, smoke simulation, etc generators in scene?
In the scene I faced the problem initially the most fancy thing I did was normal mapping.
But since it also happened with the default cube and only camera movement I don't think thats the reason.
What exactly do you mean by "medium quality settings"? Low sample rate? The mentioned project was at 512 samples min/max. But with the default cube I did not change the default sample rate.
To anybody having this problem a workaround is using a script to render each frame independent. I did not write the script, see credit at bottom.
scene = bpy.context.scene #variable that fetches current scene
outputDir = scene.render.filepath #variable that fetches output directory
filext = scene.render.file_extension #file extension suffix
for frame in range(scene.frame_start, scene.frame_end + 1): #note "frame" is just a variable
filepath = os.path.join(outputDir, str(frame).zfill(4)) #variable for file checker
if os.path.isfile(filepath + filext):
print('File exists, skipping to next...')
scene.render.filepath = filepath
time.sleep(3) #wait time in seconds after each frame render, inscreasce if there are dependency/driver related errors
scene.render.filepath = outputDir

#The name of files will always be frame number (eg. 0000.jpg), Its recommended to separate different takes/versions by folders
#This script will use Output settings that you have defined in Properties tab
