yea we need that to not to have opacity materials… it’s there in editor (isolate) but can’t find it in c++/BPs
edit:
/**
* Show/Hide Material - technical correct name for this is Section, but seems Material is mostly used
* This disable rendering of certain Material ID (Section)
*
* @param MaterialID - id of the material to match a section on and to show/hide
* @param bShow - true to show the section, otherwise hide it
* @param LODIndex - index of the lod entry since material mapping is unique to each LOD
*/
void ShowMaterialSection(int32 MaterialID, bool bShow, int32 LODIndex);
already there
