See the following attached image. This is the same mesh/material but it looks completely different in each one. I’ve built lighting, and it still happens.
Thanks!
What does the lightmap look like?
What lights are you using in the scene?
What does your material node network look like?
I don’t have a custom light map, but my resolution is 128 on the asset.
My mat node is so simple – it’s a master mat with 2d parameters for each material channel. I’m instancing that and putting my textures into the fields.
My first guess would be your normal map isn’t using the Normal Map texture group, check the texture properties.
Does this issue happen when the normal map is unplugged? Does this issue happen with a new material with all your textures plugged in?
That was it! Thanks so much. It was actually the “sample type” that was wrong – was set to color instead of normal.
