Hey @supete , the odd shading is due to inverted normals – it looks like those faces are pointing inside out. To fix this, select that area and hit Ctrl+N to recalculate.
What I’m not sure of, though, is why that would effect the render at all. I double checked the original start file and I can’t replicate this issue. Here’s a few things you could try to troubleshoot:
- See if the mesh is assigned more than one material by changing the grill’s viewport color to something like bright red and seeing if the dashboard’s viewport color also changes with it.
- Check the outliner to see if there are any hidden objects that you don’t see in the viewport but that might show up in the render and overlap that area.
If that doesn’t do it, feel free to upload the .blend to dropbox or pasteall and I’ll take a look at the file.
