When the render engine is to open source?

[generatemotion]

Hi

I find the renderer engine is downloaded from repo, when this part is to open source?

Because the client incorporates assets and code that cannot be redistributed according to their EULAs, it is currently not released as raw assets and code but rather as executables. The executables are permanently free to use. We are considering reimplementing the restricted code or making the client open source in a modular way. The specific timeline has not yet been determined.

If you currently need certain features for the client, you can request a new feature. If you want to contribute to the client code, you can contact us. If you want to learn about the rendering part, it is extended from Unity URP, you can learn about it.

thanks too much. The client start too slow, I find the server use gRPC , that means the client will poll, is that?

[generatemotion]

could you share the client code to me, i want to study the implementation details

The communication of gRPC is efficient, it should not be the reason.
I calculated the startup time with the following script:

from legent import Environment, ResetInfo, generate_scene
import time

start_time = time.time()
env = Environment(env_path="auto")
print(f"Launch Time: {time.time() - start_time:.2f}s")

scene = generate_scene()

start_time = time.time()
env.reset(ResetInfo(scene=scene))
print(f"Reset Time: {time.time() - start_time:.2f}s")

start_time = time.time()
for i in range(10):
    env.step()
print(f"Step Time: {(time.time() - start_time)/10:.2f}s/step")

env.close()

And the results are as follows:

Launch Time: 2.04s
Reset Time: 0.83s
Step Time: 0.02s/step

I would like to know how long it took to start on your machine? 2s is a normal startup time for a 3D environment, considering that the environment will be used for a long time after it starts, this should not be too much of an impact.

thank you very much for your excellent work on LEGENT. I am interested in using it in a project, and I would like to ask for the following:

If possible, could you provide a version of the engine with only the distributable code/assets, i.e., excluding parts that cannot be redistributed?

For the parts that cannot be redistributed, would it be possible for me to prepare those parts on my side separately (or get instructions on how to obtain them)?

This would greatly help me to integrate and deploy your engine in a compliant way. Thank you very much in advance for your support!
