Polargrid free CPU rendering


PolarGriD writes:

This free program is for Blender Artists who have great ideas but no render resources. Polargrid is supporting the Blender Community with this offering. We see this as an investment into the Blender community. The only limitation is the resolution of your output images; The free service is limited to a frame size of 1920 x 1080 pixels. Your projects will render on incredibly fast GIGABYTE AMD EPYC ROME 7642 48Core Blade Systems. Much faster and more reliable than any other free or paid CPU Blender cloud service. The machines run on green energy in our new Datacenter in Boden, Sweden.

      Oops, the manual seems meant for an Old Blender version
      in Blender 3.0, there is no email or Token request field.
      if you turn on the plugin, gives you a huge exception error message.

  1. plug-in works
    read the manual
    follow the steps after the initial error message (read it !!!)
    follow the manual

    IT WORKS !

    • Nope ! No Add on preferences showing for me at all !!! in Blender 3.0.
      When I turn on the Add on , I get a Bible size error message , and instalation therefore can’t be successful.
      Thanks anyway.

    • Please stop posting same comment. The error for me is not when installing the addon or requesting the token.

      Here's the console message:

    You are Welcome .
    Hopefully, the manual will be updated or someone will give us support
    , my error message is similar.

  3. The comment on the programmer to the error message is this;

    Think the user has a different add-on installed that conflicts with ours (blender_asset_tracer is an older version). Would advise to disable blend file compression or try disabling other add-ons.

  4. is this working for someone ?
    I can upload a job but then when trying to access the jobs-website i just land at a blank site. Is there any trick or is it just not working currently?

  5. i even never seen it in cpu cycles menu
    i no pro i just wanted to test but i failed at both, the plugin and the 'i cant use blender' interface

    • i just tried again .. no luck. I land on the same white page as before. I changed default browser from Safari to Opera and i'm getting an error saying that this page doesn't work

      Can i contact you somewhere other than what's app (as i don't have that)?

  6. i finally got polargrid rendering to work (i had to redo the token auth thing in order to get to the job website)

    So it renders nicely, but when i want to get my results i have to down load a couple of zips with my images… wich would be okay, as this service is free.
    But it also downloads very slow … maybe 3-400kb/s.
    Often it doesnt work at all.. i'm getting just gateway errors.

    I’m curious if this gets any better or more comfortable when i book a flatrate?

    Does anyone know a way to contact them per email? (i don’t have twitter or whatsapp)
