[lwrp] Different Light Results On Opengles And Vulkan

Unity Engine
1

Hey guys,

I just made a scene with terrain and a global directional real-time light using Unity 2019.1.0f1 and LWRP 5.10. I deployed a build to a Samsung Galaxy S5 and a Samsung Galaxy S7. Since the S5 is using OpenGLES to render and the S7 renders with Vulkan I guess that makes the difference. My project is using a linear color space.
See attached picture how different the results are. Can that be solved? Did somebody has the same problems and solved them?

Thanks.

Hi!
Can you try disabling Auto graphics API and selecting OpenGL ES 3 as the only renderer and see if there is a difference on S7?

I was able to reproduce this locally, a fix is on its way :slight_smile:

Hi!
@aleksandrk : That’s awesome that you found the problem. In which version the fix will be in? What was wrong.

I can’t say, in which version it will appear yet as I don’t know :slight_smile:
I’ll make a reply here when I have the info.

2019.1.4f1 will have a fix for this.
