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"

VR teleport ray trace collides with opacity mask

Hi everyone,

I am trying to get the ray trace from the VR teleport (from template) to go through voids created using a material's opacity mask.

More generalized question: I'm having difficulty getting the opacity mask on a material to work properly with collision.

Thanks

You can specify within the teleport raytrace what kind of objects will give successful hits.

Buuuut the actual problem you're having is that a raytrace doesn't care about opacity, you'd need a custom collision mesh that mimics the form of your object to get this to work.

E.g. a round mesh for a snowflake instead of a square polygon.

So I was able to have the teleport arc ignore the landscape by turning it into "World Dynamic" instead of "World Static". Problem solved!

That's great! Please mark this question as resolved :)

Thanks for your response!

Ah damn I had a bad feeling about that... So I managed a work around and ran into another similar issue.

I have a landscape that I don't want the VR navigation to interact with at all. I have all collision turned off and navigation turned off as well. It prevents navigation but the teleport arc is still stopping at the landscape when I want it to go all the way through. I'm not sure if there's a setting I'm missing but "no collision" doesn't seem to do the trick.

As a work around I suppose I could export the landscape as a mesh and import it to get the desired result but I feel like there must be a way to have the teleport arc ignore this landscape entirely. (maybe by tag?)

Thanks
