Building Open World Landscapes with Unreal Engine 5
By :
We have seen in the previous exercise how it is possible to create a gold material using three simple nodes composed of floats (values). But this is not possible when we talk about 100% PBR materials, so we must understand the correct use of textures in Unreal Engine.
We’ve used values for color (float3), roughness (scalar), and metallic level (float). These inputs also accept texture maps, which must meet specific criteria for file format and resolution. Unreal Engine supports various image formats, including JPG, FLOAT, JPEG, PCX, PNG, PSD, EXR, TIF, BMP, TIFF, TGA, and DDS.
Texture dimensions are crucial, as not all resolutions perform equally in the engine. Ideally, textures should have dimensions based on powers of two. In the following table, we can see the progression of texture resolutions in powers of two, a very useful property that Unreal Engine can leverage.
