Weird Lighting / Shadow Since 5.1.3 Update

try to change the shader of this model. like legacy shader > transparent > cutout or cutout diffuse . or Please tweak with other shader it will help you. I also have the same problem I have changed my shaders and it helped me.

Hmm.. I'll take a look at that when I get home later today, but it is not displaying the issue in the editor nor was it occurring with the previous build and I am not using any transparent shaders on the model so I am a little skeptical.

@itsharshdeep if you convert your comment to an answer, I will mark it as correct.

I was using Legacy Bumped Specular, which AFAI$$anonymous$$ has nothing to do with transparency, and after converting it to use the new Standard shader the issue went away.

I'm not totally clear how it became an issue, but I don't have a reason to stay with the legacy shader so I am happy with this as a fix.

Thanks!
