Hello,
I’m new to Unreal and tried to follow along the “Intro to Materials: Adding Textures to a Material” video on youtube. I don’t have the slightest clue what I’m getting wrong but I keep getting error! under “Lerp” and I can’t figure out what that’s about. Any help would be very appreciated.

A picture of the material would help.
Hey, thanks for the reply. Don’t have a picture unfortunately. I’m about 15 minutes in to doing tutorials so my knowledge about materials and what they are is virtually nil. Pretty sure I haven’t actually completely made one yet.
I’m basically following this dude along and hoping for the best:
I’m stuck roughly at the 9min mark.
Take a screenshot of your graph or at the very least tell the error message in the material editor. Without this info no one can help you.
Like he said ( below ).
Hi MMMarcis, thanks for checking in. At the risk of sounding like an idiot, I thought the screenshot I posted was the graph… I see that it was in fact the material editor.
The error message I get is: [SM5] (Linear Interpolate) Coercion Failed: Local2. rgba: float4 → float

Not sure if that’s what you’re referring to but I’ll attach more screenshots in a sec.
It’s a very old version of the engine. They must have made changes to how lerp works. To get rid of the error you need to plug in RGBA in either A or B of the lerp node. Like a texture or a constant 4 vector.
Great! Thanks for the quick reply and sorting that out for me, I really appreciate it.
No problem. Good luck!
