Please, take a look at this old post about the Dynamic Prototype feature to make sure you use it in the way it was initially designed: > [@Defold 1.4.3 BETA](https://forum.defold.com/t/defold-1-4-3-beta/72645/16): > > I wouldn’t recommend such usage of the feature. Our build system counts components in a world (the collection spawned using collection proxy). If some component’s count is static - then this collection will allocate this exact amount of memory, if some components are dynamic, then count will be taken from game.project. So, fo example: Collection (world spawned with collection proxy) -go --sprite --factory with `Dynamic Prototype` unchecked ----go ------label will allocate 1 sprite and labe… Our build system builds only linked resources. If you never link the resource anywhere, it will not be built. A ‘linked resource’ in this case means being specified in a factory or in some other place specific to that resource. It’s not enough to be in the project folder. If you want to have a few levels in your game, just create a few collection proxies (or collection factories). --- _[View the full topic](https://forum.defold.com/t/lack-of-information-about-using-dynamic-prototype-setting-for-collection-factory/75832)._
