    Hello,

    I'm upgrading a project to the Lightweight SRP and I've a problem with my terrains, they're all pink. I changed the default material by a custom one Lightweight/Standard Terrain, but it doesn't fix the problem.

    Do you know what how to fix that?

    Thanks!

    Hi,

    Terrain is a WIP feature in LWRP. We are working to get it working asap.

    Thank you! Is there any tips to get it partially working? Because a new terrain works.

    Terrain engine renders in multiple passes. You just need to change the Lightweight Standard Terrain shader add support to Base (renders terrain in distance) and Additional Passes (in case you have more than 4 splats).

    It should be straightforward to do. For shading lighting in LWRP you can just call GetMainLight(posWS) or GetLight(lightIndex, posWS). That will fill for you a struct with everything needed to shade a light. You can use the code in github as reference if you have that loaded as a package: https://github.com/Unity-Technologies/ScriptableRenderPipeline

    Is there a way to put a texture RGBA as to specify where each texture should be applied? The terrain material for lightweight renderer has no options nor parameters.

    I can paint but I would like to avoid painting the hole terrain as I had a map procedurally generated in an external app.

    Thanks in advance
