Large number of unplaceable objects in scene

[edessa]

Hello,

I am attempting to load 15 random objects in the scene through the comm.expand_scene(graph, randomize=True, random_seed=seed, ignore_placing_obstacles=True) command, run for each object. I find that of the 15 objects, on average only 8 to 10 are successfully loaded, where the unsuccessfully loaded objects show up as unplaced in the message returned from the expand_scene command. I am making sure the loaded objects adhere to the arrangements specified in object_script_placing.json. Are there any more constraints when it comes to loading objects? A log of unsuccessfully loaded objects is shown below, shown as: success obj obj_parent relation message:

Hi! Seems to be an issue with the coordinates or overcrowding. If you give the coordinates and rotation a lower precision number (preferably ending with a 0), the issue could be solved since every reset causes the coordinates to changes slightly due to Unity Engine related factors. This in turn causes the relations to sometimes change or in other cases prevent objects from being placed in the environment. @xavierpuigf @MicroSTM please feel free to join in if you think it might be some other issue.

@edessa Did you ever resolve this issue? I am having a similar one at the moment with the same unhelpful failure message when I try to place objects on a kitchen table.

[kswain55]

@mullenj Hmmm, would it be possible to show some screenshots of the kitchen table, so I can replicate the issue. Thanks!!!

[mullenj]

@kswain55 Thanks for the help! It's the kitchen table from room 0. I've cleared off all the objects so collisions wouldn't be the issue. I've also tried a number of random seeds and removing the random arguments entirely. This sample is with 'salmon' and a set pre-fab but I've had the same issue with a number of objects including the candle, chef knife, dishwashingliquid, and painkillers. The only objects I've successfully been able to spawn on the table are milk and beer.

Things seem to work fine with v2.2.4 but in version 2.3 I encounter this issue with almost every object.

[MicroSTM]

If you are using Linux, could you try this v2.3.0 executable: https://www.dropbox.com/scl/fi/jcaq5zu9yudrf4pdbifaq/linux_exec.v2.3.0.x86_64?rlkey=z0pbmm0droahes55a09o6j9hm&dl=0 I have been using this without problems

[mullenj]

Thanks @MicroSTM I've been running it in windows as I eventually will be using unity to add some custom objects but I'll spin things up on my ubuntu machine and try that executable.

[mullenj]

@MicroSTM Also, which version of ubuntu are you using? My machine is currently running 22 but I've seen reports that 22 isn't fully supported and I have been having some issues. Trying to figure out if the issues are on my end or not.

[MicroSTM]

I use 22.04

[mullenj]

@MicroSTM Sorry for the delay, I was away. I'm still running into the same issues with this executable on Ubuntu. However, I have no issues when using the v2.2.4 executable. I was hoping to use the procedural generation ability of v2.3.0 as some point so if you have any ideas on how to solve this or have some code that allows you to place salmon or painkillers on the table in scene 0, let me know so I can try it. Thanks for your help!
