ECS/DOTS and Static GameObjects

Hi everyone!
I face with strange mesh behavior when using static objects, some meshes are disappear.
In Blender I created 2 cubes and each one has its own material applied.

I also applied all transforms, then export it to the single .fbx file.

The FBX Model Import Settings:


In the inspector I added the Convert To Entity and Static Optimize Entity components. Note that the Static checkbox in the editor is disabled (I'll enable it later and show you what happens):


So I run this and it looks fine.

RenderMesh fields contain Cube_01 and Cube_02 meshes.

Let's enable the Static in the editor and run...

Now the second cube is lost somewhere... The RenderMesh fields have no previous values, they contain a Combined Mesh.

Why is this happening? How can I use static objects correctly with ECS / DOTS?

I'm using Unity 2020.3.0f1 with the URP 10.3.2, Entities 0.17.0-preview.41, Hybrid Renderer 0.11.0-preview.42.

 

If you have SRP batcher enabled, then you shouldn't tick Static checkbox on GO.

 

Thank you for your reply! I turned off SRP batcher but it didn't help...

Something tells me that the problem is in the Combine Mesh... or Convert To Entity doesn't work correctly

I just set Transform values for each cube




Now I see 2 cubes.
(Since the SRP batcher doesn't affect anything, I turned it on)

Can someone have a suggestion?

 

Ah, do you have static batching in project settings enabled too? For hybrid rendered you should untick it. Always. I remember @Tim-C told me about that half of a year ago

 

Okay I get it now

Thank you once again
