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"

Wanting to use bump offset parallax combined with a refraction effect

I'm wanting to create a material like the one used in the "Showdown" demo shop windows but with an added refraction effect on the "window" that distorts the parallax background (like water droplets).

The "Showdown" demo uses Bump Offset to shift the texture(s) as your perspective changes and I've gotten that part to work just fine. However, I'm not sure what to do to the material to have droplets that further distorted the already distorted parallax background texture.

Here's an example conceptually of what I'm after...

I expanded on this question in the forums and got an answer from Legend286 which did just what I was looking for.

Take your parallax uv and add a normalmap's RG channels multiplied by a small number to it, that should do what you want without wrecking the parallax.

Here's the forum thread:
