Re: UDK - Shadows - Dynamic, Vertex and Self
Sure. Quite a few things going on here (SSS, 'physical' lookup-based specular, rim light, AO and translucency mapping), but it comes in at about 120 instructions and 5 texture lookups (3 on greyscale, one colour, one normal), including a 'physical specular' rho value lookup texture. Note in particular the translucent ears… -
Re: UDK - Material - Oren Nayar Help
Vailias, awesome! Any idea about storing the alpha beta values in a 2d look-up? Acos isn't very lightweight, and precomputing a 2d look-up texture could reduce the instruction count a ton (I believe the link I linked above reduced it to 27 for the pixelshader). The texture lookup shouldn't change for the alpha-betas(you… -
Re: Toolbag 2 is on Steam! | Marmoset Toolbag 2 | News & Announcements
It would be similar to the LUTs you can use in UDK: https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/ColorGrading/index.html Basically, you have a standard lookup table that people can load into Photoshop, do post processing on, and then load into the engine. This lookup table adjusts the scene… -
Re: Shader Fill per channel vs per pixel
There are really many important factors to consider. Eg more texture lookups press on the bandwidth usage, one of the most limiting factors on modern (desktop) GPUs. On the other hand, if you lookup a small texture, which could be completely cached. In the latter case it would not be that important. Then it comes down to… -
Re: Removing AO from photogrammetry
Although I'm not familiar with how Epic have done it, from my understanding, you can somewhat successfully remove lighting from a texture by doing the following: 1. Photograph your object from many angles. 2. Photograph a chrome ball in place of your object. 3. Process your object, outputting a mesh + texture. 4. Create… -
Re: LOW-POLY ART
That's easy. ;) Go to Customize --> Preferences... --> Viewports --> Configure Driver, then check the "Nearest" option inside the Texel Lookup group, and also check "None" in the MipMap Lookup group. Done! -
Re: Online Zbrush class test run?
def doing it. Email info@futurepoly.com for hookup on details. -
Re: Value map driven color gradient?
yes - its simple to implement eg. index into a lookup-texture using the valuemap . eg. color = texture2d(value, vec2(value, 0.0)) in unreal you can also use a curve atlas in place of a manually created lut texture . you can stack and swap these easily from blueprint so could be very useful. -
Re: Medieval Village - UDK
Thanks Zakafein ! I don't have my project with me right now, but I can tell you really quickly how I achieved this plus a few links that you might have seen already. I'll try to get some screens up tonight. FOG : I have a really dark blue sky color and 3 fog actors that brighten up the sky using height fogs and an… -
