Could a large, open world game like GTA V be developed and uploaded to the web browser via PlayCanvas? Any file/memory size limits? Sorry for the noob question
Technically, yes it is possible.
Yes there are memory limits but that more device / browser dependent than PlayCanvas.
Files/assets are unlikely to be that big to worry about tbh. If you have an asset or file that you are questioning if it’s too large, it’s likely to be too large to give a good experience on the web
