Hi !

I don't have any chance enabling gpu renderin gon my laptop. But I can take advantage of external compute power.

I would like to enable my .blend to have gpu rendering even if I cannot activate it on my laptop.

The following python code won't work :

Code:

import bpy bpy.context.user_preferences.system.compute_device_type = 'CUDA'

How could I do this ?

I really need this, really.

Thanks !

I think the problem is the order that scripts run at launch. Cycles is an addon -> addons are loaded after startup folder scripts.

Perhaps some way to delay until blender is finished launching, make sure cycles is loaded/activated, then try your line of code line?

I have my prefs set up in a startup script, all works except the enabling cuda part.

heres that prefs.py:

Code:

import bpy #\\\ AUTHOR = 'dust' #/// def set_prefs(context):     prefs = context.user_preferences     filepaths = prefs.filepaths     filepaths.font_directory = "/Library/Fonts/"     filepaths.animation_player= "/Applications/djv-0.9.0.app/Contents/MacOS/djv-0.9.0"     filepaths.animation_player_preset = "DJV"     filepaths.image_editor = '/Applications/GIMP.app'     filepaths.texture_directory = '/Users/dust/Pictures/texture/'     filepaths.render_output_directory = '/Users/dust/Desktop/'     filepaths.show_thumbnails = True     inputs = prefs.inputs     inputs.use_mouse_continuous = True     view = prefs.view     view.show_splash = False     view.use_auto_perspective = True     system = prefs.system     system.compute_device_type = 'CUDA'     #\\\     system.author = AUTHOR     #///     edit = prefs.edit     edit.use_enter_edit_mode = True     edit.object_align = 'VIEW'     bpy.ops.script.execute_preset(         filepath="/Applications/blender.app/Contents/MacOS/2.63/scripts/presets/interface_theme/Elsyiun.xml",         menu_idname="USERPREF_MT_interface_theme_presets") def register():     if not bpy.context.user_preferences.system.author:         #\\\         print('setting preferences for author:',AUTHOR)         #///         set_prefs(bpy.context) if __name__ == "__main__":     register()
