What about lightmap resolution on the masked mesh, that casts the shadow?

hold on, let me test that, currently its set to default, maybe thats the problem

unfortunately, thats not it man @Deathrey is it possible that unreal cant read shadow from thin objects well?

Hi Mo_io,

I was unable to reproduce your issue with the information provided. Could you test a few things to help narrow things down.

Test Steps:

  • open the default map and add a cube from the Basic Tab
  • Scale the cube so that is is shaped like a wall
  • Place your shadow casting object in the scene so that it casts a shadow on the wall
  • Adjust lightmap resolution on the cube mesh to be 2048 (wall) then Build lighting

Here is a screenshot of my test results:

Let me know how the test comes back on your end.

hi Ed, for the response, i will try it later, what light are you using btw?

The default directional light was used with default settings. I made sure it was set to stationary before I built lighting.
