Line Renderer Support?

[Trey Hayden]

Hey there!  The new SSRR library seems to have a strange time handling Line Renderers (see below). 



The reflected angle seems to be off and doesn't display properly.  Would like to leave a nice review on the Asset Store, hopeful that this is a quick solution.

Thanks!

Hi Trey,

This is a limitation of all SSRR with transparent materials. The workaround is to make the effect render before transparent objects.
Go to Global Settings and change this option:


Screen Space Raytraced Reflection performs a depth-buffer raytracing. Since transparent objects do not write to this buffer, the reflection you see on the floor is actually the line render color on the wall reflected on the ground.

Using a tweaked transparent shader that also renders to depth can also work. Try the attached material/shader.
Note that this is a "trick" and could not be perfect but it could be a workaround for this case.

Oh I had no idea, reading around and that does seem to be a known limitation.

Thanks for the info and help with workarounds!

Yes, by design, as with any post effect that relies on depth buffer: fog, etc. Anything like that requires special treatment. Usually it's not a big issue or a workaround can be implemented.
We're experimenting with reusing the last frame as an option so anything in the scene could be reflected.
