UE4-Material roughness/normal slot greyed out when blend mode is changed to translucent??

melviso

Having this issue;


I don't know what might be causing this. I am getting a texture streaming pool warning whenever I open the project so I increase it in the output log command. Would this have any reason why the roughness, metallic and normal slot are greyed out?

Those are 2 different issues. The materil doesnt have those slors, because blend mode is set to translucent,  and this translucent type doesnt support those material attributes. If you scroll down to the translucency section, you can change its mode to non directional, directional forward rendered, and there are a few more.  Use one that supports roughness and normal. The forward one for example.

About the pool size warning:

You exceeded the default texture streaming pool size, which is 1 gb of video memory (in all of the versions I think) You can manually change it in an INI file.

Worked like a charm. Thanks a ton, Obscura.
