Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How do you change the player size/scale (and IPD to match) for a VR game without screwing up head tracking?

I would like to basically have a "tabletop" style game. The problem is I can't build the table at a tiny scale without physics getting kind of wonky. The solution would be to build the world at a normal scale and then to make the player larger but I can't figure out how to do this while still having head tracking be proportional. Also hopefully the ipd would scale as well so that the table feels like it actually is a small table in front of you.

Will someone please answer this? It's been 3 months and still there seems to be no way of dealing with this issue.

Hi. Have you tried adjusting 'Settings>World Settings>World to meters' ?

It looks like it works for me (I'm trying to solve the inverse problem, make player smaller. The problem is that in my case I have to adjust that parameter during gameplay and I don't know the way to do it.)

There is a SetWorldToMetersScale Blueprint node.

AxSolar, did you have any success shrinking your player? If so can you share your results/blueprints?

Hi. Sorry for the delay. Yes, in fact I've just done it this week since till now I've been using the World Settings solution only. But the node mectioned by antoinegloum works great. In this BP I toggle between two scales. Here the original settings>World Settings> Worldtometter was initially set to B value (2.88235), so we begin with user at about the same scale as the bee, standing over the leaf. Then after pressing "-" A is executed and user gets normal human size (right image, scale 100) and the bee is seen as a small insect. Pressing againg "-" returns user to insect size. BP user view
