Lighting turned to flat-bright with merged model

[design7]

I was working on a project and the lighting was fine. I merged a file (Evermotion 3D plants/grass) and now the lighting is gone. Below is the before and after. There are no new lights, etc. I tried merging rendering settings from older files, but that doesn't change anything.

How do I fix this? I deleted all of the Evermotion 3D from the scene.

Before:


After:

Merging everything, including rendering settings, seems to have worked. Any idea what the problem was or how to fix it next time (this was a tiny file, so not a big deal, but a larger one would be)?

Thanks!

Hard to say. It will be best if you send us your scene. You can do that here or through our contact form: https://support.chaos.com/hc/en-us/requests/new Please do not forget to collect and send all assets (textures, proxy models, etc.)

Hi, merging worked. I saw some error about a material not being compatible with the Evermotion file, but that hasn't caused catastrophic problems like this before.

If it shows up again I'll send the file.

THanks!
