Render Mesh Dark Spots

[jp.scholz]

Hello,

I tried to render a OBJ File exported from Tinkercad. The preview looks fine but the finished rendering has a dark pattern in the back. I changed settings for shadows/lightning but it didn't change anything.

Can anyone help me resolve the issue?Thanks!

JP-

It looks like your material is really shiny.  You might try rotating the light source a bit and re-render and see if that makes a difference.  It could be a reflection of the environment.

If not, do you mind sharing your model so we can try and reproduce?

Thank you-

Brad

Hi, I rotated the light source and also changed the material but it doesn't seem to make any diffrence. Only rotating the object itself changes the outcome of the rendering.

I attached the project file. Thank you for looking into the problem!

Thank you for sharing the file.

I was able to recreate your issue if I rendered using the Render icon (the teapot), but if I rendered as an in-canvas render, it rendered correctly.

So, you can do an in-canvas render and then use "Capture Image" to save it locally on your machine.

The last thing you could do is to just re-create the cylinder part in Fusion 360.  After creating the cylinder part, turn off the mesh cylinder part and then render.
