This is almost definitely a client side issue. This has to do with a strange issue with directly adding textures to samplers/instances.
If i try to drag a texture into a material, there’s no issue at all.
If i try to drag a texture into a pre-existing sampler or instance if the texture was imported AFTER last time the engine was shut down everything works perfectly fine as intended
If i try to drag a texture into a pre-existing sampler or instance if the texture was imported BEFORE last time the engine was shut down UE4 doesn’t let me add the texture to a sampler or instance for absolutely no obvious reason whatsoever. No errors. It just doesn’t let me.
This has been going on for the entire time i have ever used ue4 from the start to this very moment. I have been using it for i think a half year and have never seen anyone else encounter this, nor anything close to a fix, after reinstalling over 6 times and other generic or non-generic fixes.
No im not doing something dumb like trying to put a render target or cubemap into a Texture 2D slot.
