Uknown extension 'uasset'

I just got unreal engine and decided to get some foliage addons. Since I have never made games before i didnt want to waste money so I got a free grass mod. Only some assests from the addon loaded. Others just said Uknown extension ‘uasset’… I added them to the project folder, but it did not fix the problem.

Here is the video of the mod I got: Unreal Engine 4 - Advanced Cinematic Grass Blueprint *FREE ASSETS* (Updated: 5/6/2020) - YouTube

If you navigate to the explorer view by right-clicking on the asset in the content browser and selecting “Show in Explorer” does the extension match the working ones?

when I do that it brings me to the folder where the assests are, even the assests that don’t show up are in there. I don’t get why some assests load and others don’t.

Hmm I downloaded the project to have a look myself and was unable to recreate the issue. I’m assuming you followed this tutorial Unreal Engine 4 - Advanced Grass Blueprint Tutorial - YouTube

Do you get the error when you open the project or is it after you migrate the folder to your own project?

If it is after migration, can you try adding it to an empty project to see if there’s still an error.

Great news and good luck!

I got it to work now thanks. Seems the project was messed up or something…
