![]() Might / might not work, I have seen reports the Gimp 2.10 TGA export is not 100%. tga file and going back to the title, decomposing that image gives the same as the edited image (7). With the selection off, the image / layers / channels looks like (6)Įxporting to a. Some grey value painted in ? With the green channel active paint in the selections with your value.

Black (0,0,0) is totally smooth and therefore very reflective. white (255, 255, 255 rgb) is very rough, and therefore isn’t very reflective. The roughness channel tells the sim how rough the surface of the object is. Easiest way is Layer -> Transparency -> Alpha to Selection With the red channel active, painted in or out, black or white. If the pixel is non metallic you use black (0,0,0 rgb). If the pixel is metallic, then you use white (255,255,255 rgb). Metallic: This greyscale texture tells the sim if the pixel is metallic or not, or something in-between. Our PBR spec maps use 3 different greyscale maps, Metallic, Roughness, and an Alpha map used to mask out lighting effects To keep from having to have 3 different tga files to represent this, we instead use the RGBA channels in the TGA to house all 3 textures in one file. Dont be put off by my Gimp, the default black theme and cluttered layout does nothing for me. This a starting out made-up image (1) showing the channels dock (2) and the image decomposed (3) to show equivalence. The RGB channels in Gimp can be edited and be a partial edit. Layer masks and clipping masks are essential image editing tools that let you combine layers in advanced and powerful ways. Looking at your screenshot, white shapes on transparent background to adjust ? Is that correct ? Post that, or part of it, with all the layers as a Gimp xcf file, someone might sort it out. I did look at the game site and their screenshot of editing a psd file. You need a games user (which is not me) so keep visiting in the hope that one turns up.
