Thank you very much for reporting.

Could you ensure that ImportSettings in "Plugins/WebGL/2019.1/opencvforunity.bc" is set as follows?

Regards, EnoxSoftware

[mbaranovskyi]

Thanks for the fast answer! Yeah, it is set as on the screen

[EnoxSoftware]

"Assets\OpenCVForUnity\Plugins\WebGL\2021.2\opencvforunity.bc" had the wrong file name and the correct ImportSettings were not set. Could you rename opencvforuntiy.bc to opencvforunity.bc and run "Set Plulgin Import Settings" ?

I've uploaded the modified package to AssetStore.

I have updated plugin double-checked that names now is okay but still doesnt build with that log `Failed running python2 -E "/Applications/Unity/Hub/Editor/2020.3.4f1/PlaybackEngines/WebGLSupport/BuildTools/Emscripten/emcc" @"/Users/mbaranovskyi/Downloads/Udistortion/Assets/../Temp/emcc_arguments.resp"

In my environment, the build was successful without any problems. Unity2020.3.4f1 macOS 10.15.7 One of the possibilities for build errors is that there may not be enough space left on the HDD.

output.zip

[mbaranovskyi]

I have tried on different environments and different unities versions, different OSs but have same error dor the Development build. As i can see output, you provided, is from release build, but i can build release build, have problems only with development one

[EnoxSoftware]

I was able to reproduce the build error in my environment. I am currently investigating the cause of the error.

[EnoxSoftware]

For Unity2021.2 and above, the Development Build does not seem to generate any errors.

[mbaranovskyi]

but It would be much better to fix it for 2020 LTS also

[mbaranovskyi]

Will this issue be fixed? have you any ETA for this?

[mbaranovskyi]

@EnoxSoftware ping

[EnoxSoftware]

I've uploaded a version that fixes this issue, could you re-download it from AssetStore?

[mbaranovskyi]

Thanks it has been fixed
