We've allowed 3D Questions and even have a tag for but now that there's a blender.stackexchange.com at what point do we flag to migrate a question over?

For example this question: How to render a 3D model like a blue sci-fi hologram? received a wonderful answer. But should it be migrated over? The person who answered it is a high level user on the Blender Exchange.

Relevant: Blender Meta Discussion "Should we migrate questions from GD?"

  • This sounds good to me, but I do have a question about how duplicates are handled. If the question to be migrated is already answered on blender, should it still be migrated? If questions are migrated and then closed, will this confuse users? (I put this on the blender meta post as well, but it has yet to get any feedback).

  • @gandalf3 the best practice (from what I've seen in migration cases) is to migrate content as appropriate, regardless of duplicates. Users being confused seems to be a casualty worth dealing with. Commented Jun 4, 2014 at 2:44

Two network-wide rules of thumb to keep in mind here:

  • Put the question on the site that will get it a better answer. For example, if it's a question about using Blender to achieve some design goal, it can move to Blender SE. If it's a question about the design goal you happen to be using Blender for, leave it on GD SE.
  • Don't migrate crap. If it's a bad question, downvote and flag (or vote) for closure. Migrating is not a way to clean up the site; it's a way to make sure each question gets the best answer it can.

Basically, don't migrate new questions by default. Evaluate them on a case-by-case basis. Is this a good question, but it's outside the realm of most GDSE users' Blender expertise? Migrate it. Is it a good question, and it has a good chance of getting a good answer here? Keep it.


Normally, the rule for questions that have overlapping scope like this situation is "if it's on topic, don't migrate it". For instance, a question about Aruinos asked on Electrical Engineering would not get migrated to the Arduino site.

However, I don't feel the situation to be the same here. ~10% of all questions on EE.SE are tagged with arduino. ~0.1% of our questions are tagged with . 3D questions on our site always feel like orphan children to me. We've agreed to take them, but they can often contrast starkly with the rest of the questions on our site.

I'm fine with migrating questions away from our site and giving them a better home. I discussed this with iKlsR (one of Blender's mods) who is okay with us doing so for quality questions.

If this is the consensus, then the proper way to handle them is to flag as "other (needs ♦ moderator attention)" and just make a note that you think it should be migrated to Blender.SE. I'll pop into the chat room and confirm with any active Blender members that it's a decent question worthy of migrating.

This would be for new questions only. Don't flag the existing 10 or so questions that we have tagged , we won't (and sometimes can't) migrate ancient questions.

  • I'd say migrate them where possible for the simple reason that Blender.SE users should be able to see them when checking questions they ask haven't already been asked and when browsing "related questions". Commented May 30, 2014 at 16:46
