Re: Unity Metallic/Metalness not showing Smoothness Slider
It still bugs me that Height is on G and not B, so you could pack R Metallic G AO B Height A Gloss Rather than having to use a separate map for Height on G, or having to choose between AO and Height. I've made my own shader that takes maps packed that way. I've also experimented with putting the AO map in the alpha of the… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
Stupidly, yes. Guessing they're assuming the gloss value will stay relatively well compressed in the alpha, with AO getting next best compression in the green. Metalness doesn't need that much to it, so it gets next best in the red. I've had to hack the Standard shaders to use RGB rather than RGA and that's a real pain now… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
Yeah, just looking through the include files. Although if you hover over the input slots in the editor, then it'll tell you in the tooltip what texture channel it derives the information from (they aren't automatically generated - it's just written out in the custom shader inspector). UnityStandardInput.cginc has the… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
Metalness in R, roughness G and ao in A? Nothing in B? That's a really dumb way to do it, and means all your textures are using double the texture memory compared to simply packing them in RGB. Is this really the default in Unity? -
Re: Unity Metallic/Metalness not showing Smoothness Slider
Woah, the AO (or height) can be packed in G for the standard shader? I've never read this anywhere! Is there a reference on the unity manual that confirms this, or was this discovered by digging the the source files? I always thought it was incredibly wasteful to only use 2/4 channels in a texture, at least using 3/4 is a… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
Yes it is, well Metallic in R, AO or Height in G, nothing in B and smoothness in A anyway. I was asking a while back(posted here and on Unity's forums) if there was a reason for this. I'll have to find the links. Some people suggested it was because of texture compression reasons, but I'm not 100% sold on that. -
Unity Metallic/Metalness not showing Smoothness Slider
Hello there folks I'm pretty new to unity, but its pretty straight forward platform to work on. There is one thing that I can't figure out. The metallic option both has metalness slider and Smoothness slider. But once I add texture to it, the glossiness slider is gone. The texture is metalness with gloss map on it as… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
I'm not exactly certain at that level. The texture is loaded into memory only once, and presumably the bit for that lookup is loaded (it knows that from the vertex shader, and the UVs don't change, nor does the mip level for that point). So it's two samples of the same texture at the same place - meaning there is some… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
you might want to look up on basic PBR theory for that, but in short, the metalness map is really just an answer to the question: Is this (the surface represented by this pixel on the texture) metal? If it is, then the pixel is white. If not, it's black. For a wood table with chrome trim, ask yourself, is wood made of… -
Re: Unity Metallic/Metalness not showing Smoothness Slider
What makes a material metal?Is it not the fact that it is reflective but how it handles reflection? For example fine wood and plastic versus metal chrome, all these can be reflective, is it how they handle reflections that makes them a metal or not? Lets say I have a fine wooden table with a nice reflection and there is a…
