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"

Problem with new 4.11 Eye Shader

Hello, i've exported the eyeball mesh that comes with 4.11 to fbx and i've imported it into maya so that i can place the eyeball in the heads that i have for my character. The problem is that when i import the head with the eyeball in ue 4, the eye shader is not working properly:

If i disable refraction i improves but still not perfect:

Do you know what could be causing this? Thank you.

Product Version: UE 4.11

Double check your UVs to make sure they didn't shift or get inverted/reversed. The refraction/bulge depends on those UVs being in the perfect spot and not inverted. I was getting a similar distortion with one eye, and found that it was because I had mirrored it in Maya.

I've imported just the fbx that i have exported from the content examples and when i apply the material it just looks wrong. The UVS in the Channel 1 look good no?alt text

I had this same problem, what fixed it for me was selecting Import Normals (rather than calculate normals) on FBX import. Also, enabling high precision UVs seemed to help even if the content example doesn't use it.

Make sure FBX export settings are correct as well, I use those suggested by the docs: https://docs.unrealengine.com/latest/images/Engine/Content/Types/Textures/NormalMaps/Creation/fbx_settings.jpg
