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"

Location Based Opacity not working as intended

I was following this tutorial: https://www.youtube.com/watch?v=CkEueafOvFg∈dex=185&list=PLZlv_N0_O1gaCL2XjKluO7N2Pmmw9pvhE And at 5:30 he talked about driving the radius of the mask with the radius of the sphere. I've followed it exactly, triple checking everything, and yet the mask is much much smaller than the sphere. And no matter what variable I try to tweak nothing works.

Also, Hardness doesn't actually change the hardness, just the size of the mask. I would like to have nice gradient looking effect, but am unable to.

HI!

It is a working example.

You need add Scene component and parenting Sphere component to it. Then scale down Sphere component.

If you want to use soft mask, you need set blend mode of material to Translucent. And connect into Opacity slot Sphere Mask node.

This is result. In Simulate mode we have some issue. Radius of Sphere changing when left mouse button released.
