4Vec to Lerp node in material crashes editor

[JohnAZoidberg]

Are material questions supposed to go in Rendering? Nothing else seemed like a better fit.

Regardless, I’m relatively new to Unreal (Unity guy trying to expand), and I’m having trouble with a pretty simple material.

When I connect the green 4Vec node to the B of the Lerp next to it the whole editor crashes and give me this

Assertion failed: bAllowNonFloat [File:D:\build\++UE5\Sync\Engine\Source\Runtime\Engine\Private\Materials\HLSLMaterialDerivativeAutogen.cpp] [Line: 156]

I’ve gotten used to Unreal randomly crashing, but this is happening consistently every time I connect these nodes. And this material is not complex at all, so I’m not sure what the problem is.

Hi, did you ever figure this out? I’m having the same issue here:

Sorry for the late reply. I did, but I don’t remember how at this point. I think I just deleted the material and made a new one the same way but it worked the second time.
