Tessellation multiplier error. "Error [SM5] error X3000: unrecognized identifier 'FVertexFactoryInterpolantsVSToDS'"
I am getting the following error inside my UE 4.10 project when trying to compile a material with tessellation mode set to "Flat Tessellation" or "PN Triangles".
Error [SM5] error X3000: unrecognized identifier 'FVertexFactoryInterpolantsVSToDS'
This error only happens in one specific project that I have been working on but not in a brand new test project. Any ideas of what I could do to fix this?

Are you able to provide a sample project that can reproduce this? If it's not happening in a new project I don't think I'll be able to reproduce on my end, and I've not seen anything stand out when I've created tessellated materials lately.
If you're able to provide a sample project, strip out anything that is not needed to see the issue to keep file size down.
If not, you may want to try clearing the Saved and Intermediate folders fromy our project folder. This will generate new files for these folders and hopefully resolve any issue that you're can't reproduce in a new project.

Ran into this problem. Unchecking the box works. Maybe have a warning when throwing a mat into particle system. Of course, might be pointless with Niagra replacing cascade.
