I’ve been trying to build a webgl game. using the unity lego microgame package.

the games menu will work but when i click play to load the next scene i get an error stating:
“WebGL: RuntimeError: memory access out of bounds.”

i noticed when i build the game i get the following error:
ArgumentException: Scene file not found: ‘’.

would anyone be able to advice what i may have done wrong ?

for anyone having this issue.

The fix was simple, the lego prebuilt mesh combiner seemed to be not working correctly.

i disabled the line :
meshCombiner.GridExtents = optimizationBounds.size;

in the BrickMeshCombiner script. found on the GameManger object.
