    Hello, I am doing an outline shader for mobile using a custom effect in the post process stack,the problem is although I use a smaller resolution for rendering the game using the LWRP Render Scale, however the post process is done using the device full resolution:
    Before Post Process

    After:
    upload_2019-1-18_15-55-58.png

    Is there a way to maintain the resolution?

    With PPv2 it's not possible to hookup the renderscale. We are starting work on integrating PPv3 on LWRP and then this will be supported.

    Oh I see, So there is no way to make my Custom effects calculations with a lower resolution unless I actually lower the resolution of the screen.

    As the PPv2 is somewhat new, Im guessing the PPv3 will take a while to come out.

    Is there any other way I could approach this, using LWRP?

    Hey guys I dropped the resolution in the render context to 240p but theres no real boost in performance even at 90p but it is easily noticable that the quality reduced whats wrong.

    It means your bottleneck is neither bandwidth or postprocessing.

    Sorry for necro. On 2018.4.. VR (Fwd msaa) single pass. No PP stack version (tried 3.0.3 to latest 2..) seems to fix the low resolution post processing. Any hints as to where we can hack in the proper resolution to fix the PP issue?
