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"

Getting Errors When I Turn On Tesselation

Hello, I've been trying to follow a tutorial on how to create a tesselated ice material. However, every time I change my tesselation mode off of 'None', I get a handful of errors in the same vein to this one.

"[SM5] /Engine/Private/DepthOnlyVertexShaader.usf(0): error: Unhandled output variable OutClipDistance [[SV_ClipDistance]] found in tesselation shader"

I truly have no idea how to address the issue other than to not use the tesselation, but it really takes away from what I was trying to learn. I'm not sure if it's limitations with my graphics card or what, but I'd love if anyone could point me in the right direction/shed some light on this issue.

Can you confirm you have support for tesselation in your GPU? If I am not mistaken, you need full DirectX11 support on your GPU to use tesselation.
