HammUEr, a Hammer/Worldcraft map importer for Unreal Engine

i am doing all lighting within UE4. only thing i import is materials and meshs

Hey i am back after doing some lighting tutorials i learned how it works, but i am still confused with “Valve VTF” textures.

i am using a map from called DR_LAND01 i lowered the sun from intensity 18 to 5 seem like overkill, but here is the problem i am having.

default dr-land texture (texture consists of multiple textures) what i want it to look like (not the multiple part the brightness)

here is the grass texture from the first pic but not mixed (medium brightness even tho texture looks way darker) looks ok

but here is the valve texture.
cs:go import texture (super bright even tho texture look darker)

im not sure what going on, is “Valve VTF” textures washed out super bright??

edit

if i set my diffuse + a constant 0.2 to a multiply i can get it look dark but seems the wrong workflow .
using dr_land01 instant material

with diffuse of grass_b (cs:go)
constant at 1

constant at 0.2
