Isaac Sim Version

4.5.0

Operating System

Windows 10

ubuntu 24.04

Using the franka life cube environment (lift_env_cfg, joint_pos_env_cfg), when toggling visibilty or moving object, the asset fades out instead of instantly disappearing. I want to capture the scene after using cameras

how can i make it so the rendering instantly makes assets(robot,object) disappear

i tried to use set_world_pose for the object but got a attribute error.

Please share a screencast video to demonstrate the asset fading effect you are seeing in Isaac Sim.

In the meantime, please upgrade to Isaac Sim 5.0.

im trying to get rid of the murky effect around the cube sometimes the outline from the previous place is in the photo.

pretty sure its caused by the asset fading out when moved so i want the cube to instantly disappear.

Have you had a chance to try upgrading to Isaac Sim 5.0?

I have to keep it at isaac4.5 as its part of a bigger project

I’m having the same Issue with Isaac Sim 5.0 - did anyone find a reason / solution by now?

The problem is caused by the anti-aliasing and denoiser that is turned on by default. These try to “smooth” between frames which causes the issue

    self.sim.render.enable_dl_denoiser = False

    self.sim.render.antialiasing_mode = "FXAA"

antialiasing can be FXAA or off

Thanks everyone for the input.

In the end this turned out not to be an asset/visibility issue but a rendering one. The “ghosting” or fading effect was caused by the default denoiser and anti‑aliasing trying to smooth between frames. Disabling the DL denoiser and switching AA to FXAA (or turning it off) removes the problem in both Isaac Sim 4.5 and 5.0:

self.sim.render.enable_dl_denoiser = False
self.sim.render.antialiasing_mode = "FXAA"  # or "None"

With this configuration, objects disappear or move without leaving a murky outline, so I’m marking this as solved.
