Re: Pro Spec and AO Map Creation tips [req]
Simply using a greyscale version of your diffuse map is sometimes the best way to do things, BUT ONLY FOR THROWAWAY ASSETS. The method is fast and cheap, since it doesn't require any extra work or texture memory, but it does not make the asset look as good as it could. Likewise, using a greyscale specular map (1 channel)… -
Re: Pro Spec and AO Map Creation tips [req]
Oh god. OH GOD NO. You can do this easily in crazybump by pasting in your normals and upping the "enhance detail" slider, what I generally use for a "cavity map". Though this just helps to add a bit of pop, or is used for creating selection masks for various effects, I would never call it "generating a spec map". Also...… -

Racer, A 1 channel map can be greypacked with other 1 channel maps, so that multiple textures can be put into a single image file. For instance, I can have one 3 channel targa that stores specular (red channel), transparency (green channel), and emissive (blue channel). So yeah, a greyscale spec map can certainly save… -

Ace-Angel: "Just" greyscaling the diffuse and "calling it a day" is the wrong way to do a spec map - it's sloppy at best but I prefer to call it "plain stupid". Greyscaling the dif is just the first step of so many more. What I do is that I copy my entire diffuse group in Photoshop, greyscale it (Hue Saturation layer) and… -
Re: Pro Spec and AO Map Creation tips [req]
Disregarding actual content creation, here is a breakdown of the technical aspects. What you're doing is trading quality for memory savings. So, in order of best quality to most efficient(yes the various methods are inversely proportional). 1. Full color spec with gloss in alpha channel, 32 bit image, compressed is twice… -
Re: Pro Spec and AO Map Creation tips [req]
yes, i've worked with "packed" grayscale textures on a few titles and every time i wished i just had colored specular and no gloss at more than one point during the projects. while it's true you can save vram with a "packed" texture, you need to put in more work to separate materials and give them color. many accent… -
Pro Spec and AO Map Creation tips [req]
Can I get some pro tips on creating spec maps for games? I've heard of people creating them from normal maps as well as from diffuse maps. I'm unsure what is the best method. Also, What areas in general are best to be brighter and darker? Also, AO maps, i've found that they add a strange look in Maya and other engines. Can… -
Re: Pro Spec and AO Map Creation tips [req]
Well I still think it's a bad idea to desaturate the diffuse straight off "just to get a quick spec". Why? Because the levels in the greyscale will be totally OFF. Things that are white in the diffuse will get extreme specularity and shine like hell even if the material is supposed to be something like paper remains on a… -
Re: Pro Spec and AO Map Creation tips [req]
In theory, yes, Engine are able to do that, but the problem is that you need to create the Post-Process effect to account for Normal Maps to give the detail, which not many people do, and which frankly can look very noisy if not done correctly. I think so far UE4 is the only engine that is going to account for that? Almost… -
Re: Pro Spec and AO Map Creation tips [req]
Yes ofc - working in parallel is the right way to go. I don't start working on my spec until I'm about halfway done with the diffuse though - but that's just a matter of taste I guess... I can't see your signature btw - you know why? :(
