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"

Smooth refraction with material applied to a sphere?

Hi, I've been working towards creating a sort of shockwave effect. Currently I have a mesh emitter emitting a sphere every 3 seconds or so and that sphere grows in size over its lifetime then disappears. The sphere's material is entirely transparent and simply refracts light. However the the true geometry of the "sphere" becomes way to clear as the refraction clearly defines the faces of the sphere to the viewer. I'm looking for a way to make the refraction smooth so the shockwave effect appears to actually be round. How is this done?

Thanks.

You could use a fresnel (node) in the material editor and hook it up with you transparency.

Turns out I just needed to go back into blender and smooth it out there. I am interested in using fresnel on this effect after checking it out. Thanks for the tip.

You want to use a sphere gradient. Bill Kladis shows exactly what you're trying to do in this livestream: https://youtu.be/dtuLOxSkciA?t=1076

The linked time is where you want to start
