I was wondering if you can access and read a texture 2D object in runtime using only blueprints ? I found a blog post showing how to do that with C++ ( UE4 - Reading the pixels from a UTexture2D - Isara Tech. ).
I want to generate a small texture map using the substance plugin (64x64 or 256x256) and access the pixel colors to create a level from it. For example the red pixels can be land, the dark blue pixels can be deep water, the light blue can be lakes or rivers and so on… But I can’t find how to do this in blueprint. Do you know how I can do this ?
Thank you for your help.
