Simple question- What is the best way to simulate chrome parts? Like a bumper of a car? What shaders could I use to create that mirror effect?
TrainUberShader: 3 textures Slot 1= diffuse Slot 2 = normal map Slot 3= "aux" (R+G+B+A) which allows you to have 4 different maps in one texture; R= AO G= Emissive B= Reflection A= Specular or you can use TrainBumpSpecEnvMask Slot 1 diffuse with alpha (RGB+A); RGB= diffuse A = combined Spec/Reflection map Slot 2; placeholder texture, use anything. I always use HDRI in Substance Painter and add some fake reflection to the diffuse texture. Then I use the specular and reflection channels to create a metallic look. Values should be close to black which is 0, white is 1. https://the-art-of-rws.blogspot.com/2010/03/shaders-and-kuju-materials.html
One of the biggest problems I have with making these RGBA type maps is separating / packing the different channels. Is there an easy way to do this?
What software do you use? I use Photoshop, and it is quite simple to work with the different channels.
I use paint shop pro, which doesn't seem to do that at all. I also used Gimp that does deal with channels, but it's not an easy task. Any recommendations? I'm not opposed to buying some new tool/program, if it make the task easy.
