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"

Niagara Static Mesh variable can't run on GPU


I am trying out a Mesh Morph effect with the Niagara editor. It all works when the effect is run on the CPU but since I want to bump up the amount of particles, I want this effect to run on the GPU to not effect the performance.

The only problem is, I am using two Static Mesh variables within the Niagara editor to get the Tri Coords and apparently this variable type can't be used with the GPU. Here is the error log,

Error: DataInterface Emitter.MeshStart (NiagaraDataInterfaceStaticMesh) cannot run on the GPU. - Callstack: GPUComputeScript

Error: DataInterface Emitter.MeshEnd (NiagaraDataInterfaceStaticMesh) cannot run on the GPU. - Callstack: GPUComputeScript

Needless to say I am new to Niagara and I couldn't figure out a work-around to this, if there is any. But it feels like having a reference to some mesh shouldn't be that hard to accomplish and all I need from the mesh is a random point on its surface.

Any help?
