Camera rendering in parallel environments

[HSL31]

Hi!

I've checked the issues and discussions regarding cameras in batched environments. I was wondering if there was any updates regarding this issue and thus if there will be any support for rendering multiple cameras simultaniously in batched environments!

Thank you, for your help.

You can check the latest example for the batched rendering.

Hi! Could you be more precise, please? I searched in the example scripts, but I couldn't find anything about multiple/parallel rendering.

I am trying to render multiple frames on parallelised envs, without looping on multiple Cameras. In particular, by defining a single Scene with one Camera, and replicating it by calling Scene.build with n_envs=4 (for example), the Camera.render returns a (single) RGB image with shape (512, 512, 3). I would have expected the frame to have an extra dimension for each env (and in the case, each frame would only display the objects of its env and not the neighbouring ones), but this is not the case.

Am I doing something wrong? Is there a way to do this?
Thank you very much!

Hi! I have the same problem when doing parallel simulations, and I can't find the corresponding examples showing rendering for paralleled environments. So are there any tricks to render images for each environment, not together?

Really appreciate your help!

Looked into camera.py for Genesis. I am going to attempt modify the setup so the rasterizer/camera can render a single specified env at a time instead of rendering all envs in a stack.

Hmm, why is this setting not default for n_envs>1? it should be.

Hi, I am also interested in this. Looking forward to any new progress from you.

@HeegerGao, set env_separate_rigid=True in VisOptions

Thanks, bro!

For me, it's now resolved by #1416
