adjust ORM composite using GIMP


Recommended Posts

So , I just posted this pic in a recent question concerning a very dark shadow in my lev


I decided that the white coming from the terrain material is too intense and wet looking .

I created the composite with materialize but for the quick adjustment Ill use GIMP

I open the composite map in GIMP to adjust the green(roughness) and blue(metalic) channels

using GIMP just select ' channels: in the layers window , you can see it in the image below

This image shows the green channel is selected and isolated . I used brightness/contrast to raise the brightness of this green(roughness) channel , raising the roughness which appears softer . did basically the same with the blue(metalness) but instead I darkened the color of the blue channel , lowering the metalness , again causing a softening effect . in the image here is the adjusted material .


the previous and next images are with a sun elevation 20

some other sun angles looking forward and behind .


next 2 are 40



next 2 at 80



sun elevation 150 over a hill


well , just coll I think . have a nicey :)
