Hi all,

Can anyone explain to me the purpose of a floattexture please? I just cant seem to understand its use?

Thanks

It literally represents black to white values or 0% to 100% It, very helpful when building materials and having sliders to control intensity.

For instance if you load a mix texture into the roughness, then add a black and white mask to the top texture slot and 2 float textures to the inputs..you will be able to easy play with the intensity of the texture to get the reflectivity you want.

But what advantage does that have over just changing the value for specular? Isn't it just duplicating?

if you load a black/white image as a float, it uses less vRAM than an RGB.
bump/specular textures are usually black/white.

This can really help you optimize your scene if you are low on space.
