Re: When applying Specular maps in Photoshop
Lets put on the brakes here. I don't think you understand what a specular map is. Let's start there. Your diffuse map and specular map will always be seperate. You rarely, if ever, overlay a spec map on your diffuse map. Spec maps are applied in engine as a seperate texture that controls intensity and other info(sometimes)… -
When applying Specular maps in Photoshop
Hi all, So this will probably be a very quick question. I'm an aspiring Environment Artist and I wanted to ask about using Specular maps in Photoshop. When you apply a Specular Map in Photoshop to your Diffuse map, and then when you import it into UDK, should you use the Diffuse map texture for the Specular port in the… -
Re: When applying Specular maps in Photoshop
In the old generation of rendering the Diffuse map is used to determine surface color and the Specular map is used to determine highlight intensity and sometimes also highlight color. Typically you load the Specular map into the Specular slot since an authored Specular map will look different than the Diffuse map. Also… -
Re: When applying Specular maps in Photoshop
Thank you all for the responses. I am going back right now and correcting my Specular maps, and I have seen an improvement so far. If I have any other questions I'll post them. Thank you :) -
Re: When applying Specular maps in Photoshop
Joopson: I did indeed create my Specular Map from Crazybump, and then I set it to Overlay in Photoshop over my Diffuse map. Would I just be able to use the Curvature map created from Crazybump and use that as a Specular Map applied in Photoshop the way I did it, or should I apply the Specular Map in Maya and do it that way… -
Re: When applying Specular maps in Photoshop
Wait, are you talking about Crazybump's specular map, or an actual authored map to control the intensity of specular highlights? Some of your comments make me think it's the former, which is what is correctly called a Curvature map, despite what crazybump wants you to think. That can be overlayed on the diffuse, and it… -
Re: When applying Specular maps in Photoshop
The specular map should be either separate file from the Diffuse or should be saved in the alpha channel if the specular map is grayscale. Yes, applying the specular map means hooking it up to the slot in the material editor. -
Re: When applying Specular maps in Photoshop
AdvisableRobin: I'm using UDK. When you're talking about applying the Specular Map, you're talking about the slot in the Material editor in UDK correct? Eric: Do you mean you apply the Specular Map in the Specular slot of the shader in Maya, or do you mean within UDK? The way I did it was that I put the Specular Map at the… -
Re: When applying Specular maps in Photoshop
You don't apply specular to diffuse. They should never be blended together into the same image. (Unless you're working old-school, with a game engine or platform that doesn't support lighting) However you may be referring to storing the specular map in the Alpha channel. If so, yes that's a valid method. Except that this…
