First time posting here. I’m really hoping someone can help me figure this out.
Creating a 3D asset for an upcoming livestream. Everything has been going great overall. The shading for the model looks the way it’s supposed to in the Viewport Shading preview window. The mesh looks fine, there’s no artifacts showing at all in the problem area. I’ve rendered tons of test renders and nothing was out of the ordinary. The render always looked like the Viewport Shading preview.
I added some keyframes for the animation, went to render, and the final render images started to look like this.
There are what looks like shading artifacts in the final render, over the front right tire and along the right side of the vehicle. This began immediately after adding keyframes for the animation. That’s all I did. I didn’t touch any of the settings or mess with the model in any way, other than to rotate the front tire and steering wheel. The mesh looks perfectly fine in the Viewport Shading Solid view. The machine gun cover on the right is also leaking a tiny bit of yellow light, that it wasn’t before. It looks as if the mesh somehow got deformed, but as stated, I didn’t touch the mesh at all between the normal render and the glitch renders.
If additional information is needed, please let me know. I need to get this fixed as soon as possible.
I’d look into your Motion Blur, Depth of Field and maybe Volume settings. If you make a copy of the file and delete the keyframes does it go away? That would seem like something with motion blur to me.
That’s the thing though. The motion blur and dof were added a long time ago, with absolutely no problems until adding the keyframes. I opened up a save file from 2 saves ago, and there was no issue with the shading.
I turned off the dof and motion blur. Removed all of the keyframes. The issue is persisting.
This didn’t appear until I added the keyframes. I have absolutely no idea what could be causing it.
Woops, hey. Figured out a solution, but forgot what it was. If I can make time, I’ll pull up the Blender file and see if I can figure out what it was. Got it to work though, somehow.
Don’t know if you’ve tried this yet, but the shading looks like it is just a problem with inverted normals, If you haven’t, just check if your Face Orientation is correct
if you see red on the outside then Tab into your model, click ‘A’ to select all, and then Shift+N to correct the normals, if you did it right, the entire model should be blue on the outside & the shading problem will be fixed.
