Thanks to ClockWorkOrange I learned of “Set Material”. Only problem is seems really buggy using it to toggle the color from green to yellow and then red depending on the distance of a vehicle. Out 5 different props, it only worked once. Even tried using a simple cylinder but it didn’t work. I read several posts indicating you have to toggle use with skeleton meshes in the material blueprint, but that made no difference for myself and many others.
Here’s the blueprint that worked. (sorry for the messy BP, it’s only my 2nd one)
Didn’t Work
Added print distance to ensure it was setup properly. The 2 freight bins with the check marks are the only ones that worked, everything else with an X didn’t.
Full Blueprint. X marks not working and ✓ worked. Spent the whole trying to resolve this with no success.
