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"

VR project not Packaging

When I go to package my project for windows, it critically fails and gives me this error (below). I really need help because the project is due soon and I am lost. I think it has something to do with forward shading.

I migrated the level to a new project using unreal vr template and then it worked.

You have several warnings: Warning: (): shader uses 17 samplers exceeding the limit of 16. Start by fixing your shaders that use too many samplers.

Where do I change the number of samples in my shaders? I'm not to familiar with the technical side of Ue4 so I'm not sure what your referencing

The number of samples is set by the platform you are cooking for. You need to change your materials to fit inside that limit.

I went through all my materials and couldn't find any that are over the sampler limit.
