Questions about BatchRendererGroup

Hi!

How to perform batched draw calls using BatchRendererGroup?
Currently i'm adding batches per each chunk, and setting its matrices from LocalToWorld. Rendering is fine, but batching is not working at all - i'm getting the same amount of draw calls as count of the mesh instances.

SRP batcher is Off
Hybrid renderer package is not added

I noticed you have been copying and pasting this response in a couple of threads. Do you perhaps have an estimated timeline for how long we have to wait for? Waiting indefinitely is rarely a good idea.

 

Thanks for the answer!

Hopefully the new API will be compatible to render on older mobile devices, at least GLES 3.0

Just tried to run Hybrid Renderer v2 on my android test phone, no luck, it needs compute buffers(
Regarding to the documentation, DOTS rendering team won't focus on mobile platforms in 2021, a bit frustrating for me

So, would be great to have some simple solution that support render on older mobile devices (their market share is still valuable https://developer.android.com/about/dashboards/index.html)
Or, at least, some low or mid-level tools to build our own renderer, because DOTS stack is performant by default which is perfect for low-end devices

 

It is possible to write a stupid simple renderer system that draw static meshes like below:

Code (CSharp):

1. [UpdateInGroup(typeof(PresentationSystemGroup))]
2. public class RendererSystem : SystemBase
3. {
4.     protected override void OnUpdate()
5.     {
6.         Entities
7.             .WithoutBurst()
8.             .ForEach((LocalToWorld l2w, SharedMesh sharedMesh, SharedMaterial sharedMaterial, MeshRendererData rendererData) =>
9.             {
10.                 Graphics.DrawMesh(sharedMesh.Value, l2w.Value, sharedMaterial.Value, 0, null, 0, null, rendererData.CastShadows, rendererData.ReceiveShadows, rendererData.UseLightProbes);
11.             }).Run();
12.     }
13. }

and it works surprisingly well enough with SRP enabled, even on old gles 3.0 device, and renders something like that: (warning! triple-A blockbuster screenshot)


But what to do with skeletal mesh renderers? Converting them manually is a super complex task
