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"

Bump-Offset holo sight is slightly off

I'm making a VR game that uses Tom Looman's holographic sight method (http://www.tomlooman.com/holographic-weaponsight-using-bumpoffset/) on most guns. I'm now attempting to create a sort of hologram sight for the shotgun; it basically consists of a large transparent plane with a bumpoffset texture applied. What I'm now noticing, since this particular gun has iron sights to compare with, is that the holo sight veers to the right as the bump offset is increased. You can see the difference here:

Comparison

I had originally assumed that this was being caused by VR in some way, but it seems to be happening in regular standalone mode as well. Is this a bug or am I doing something wrong?

In case you still need help or anybody else stumbles over this: you have to turn up the bump height and scale up the texture after you do that. good luck with your project!
