WebRTC/Screensharing sample is missing a prefab

Hi there! The CurvedScreen Variant prefab is missing from the Screensharing sample. Do you have an updated version I can look at? ā€œPrefab instance problem: CurvedScreen Variant (Missing Prefab with guid: ddc6dadc91a391c439f733ab86fb22b4). 3 instances are missing the same Prefabā€

Hi :wave:
Which Unity version and render pipeline are you on?

I had the same problem when I recently tried importing the prefab. It wouldnā€™t let me use it because it was ā€˜immutableā€™ so i copied it into my main assets folder. Then I could use it but the curvedscreen geometry wasnā€™t being found. I copied the geometry to my assets as well and replaced the one in the prefab but now when i click it it only shows in the local instance and doesnā€™t display for other people connecting

Same question to you then @VRSpatialist : Which Unity version and render pipeline are you on? :smile:

.
Just for context, with our samples weā€™re trying to do what most of the devs at Unity consider impossible: have scenes and prefabs and assets that are compatible with a wide range of Unity versions and render pipelines.

That mostly works - and we believe we can get it to work 100% - , but sometimes people (as you!) run into combinations that arenā€™t covered yet or where we run into edge cases. So itā€™s important for us to know which Unity version + Render pipeline this is happening on so we can look at that particular case.

(Pretty sure Iā€™m seeing a pattern here.)

Thanks for the additional info! Iā€™ll check it out :slightly_smiling_face: not good if it doesnā€™t work on the latest LTS!

Thanks!

In the meantime, as a workaround you should always be able to pull the samples repo (GitHub - needle-tools/needle-engine-samples: Live: https://engine.needle.tools/samples šŸŒµ Needle Engine sample scenes - use as examples and as a reference for learning šŸ˜Š) and open it with 2020.3 LTS (or just add Needle Engine to a 2020.3 project and install the samples package from the samples window)

What might help would be a button in the explore samples window to ā€˜clone sample to workspaceā€™ or something like that that would copy the sample and all prefabs into your working Assets folder so nothing in it was immutable.

Iā€™m not sure why copying the prefab though would make the curved component go missingā€¦ it should have the same GUID wether itā€™s in an immutable folder or copied into your project

Hmm, same issue with the samples in 2020.3. I can get it to work by manually replacing the prefab variants in the scene with the original prefab in the Screensharing/Assets folder. Looks pretty good, actually, so once again: very impressive work on this.

And webcam input works nicely, too.
