how do i request acess to create realistic humans?i cannot get past download page.
Hi @lettypaigemorgan , welcome to the forums 
. In the new version of Unreal Engine “5.7” you can create metahumans in the engine already. All you need to do is install the new version
Make sure that the “Metahuman Core Data” is enabled by click on the drop down menu
if it isn’t just click on the check box and click on apply and let the engine download it
Launch the engine
Create a new project
Select the template you would like to use, the platform you intend to use it for, the location of where you would like to house the project and the name you would like to give it.
Once the project opens go to the Edit menu → Plugins
While having “All Plugins” selected Type “Metahuman” in the search bar
make sure all of the corresponding plugins are selected (once selected the system may ask you to restart the project on the bottom right corner, click on restart)
once you restarted create a folder to house your content, either in the “Developers folder” or the “Content folder” by right clicking inside the Content Browser and selecting “New Folder” name it and open it
right click again inside the Content Browser → Metahuman → Metahuman Character → Name it → if “Missing Project Settings” comes up click on Enable missing
double click the meta human character to open the editor. In “Presets” you can apply bases of metahuman characters. In “Body”, “Head”, “Materials”, and “Hair and clothing”, you can play around with those settings to customize your Metahuman
Hope this helps, if you run into any problems or have additional questions, please let me know.
