Re: Courtyard
Much better, but I feel like it's all a bit too yellow at the moment. I took the image into photoshop to see if I could adjust it and get some better color range: Not perfect, but it gets away from the yellowness that was bothering me a little. You can create a color-lookup-table for use in UE4, if that's where this is… -
Re: UDK Lighting for a 'Film noir' Style scene
Interesting. I just converted one of my environments to Film Noir style last month. I initially tried to use a color lookup table (search the UDN for LUT), but that doesn't work very well if you are looking to isolate certain colors like in some movies (often red objects). What I ended up doing was running each texture… -
Re: Turning a float into texture2D?
Yeah, I can see how it wouldn't work as it would need another pass.... Some kind of render to texture and then another texture lookup. The network here is just me trying to generate a normalmap from a greyscale heightmap (one channel in this case) I know it's probably not that optimized, or good for that matter.... The… -
Re: PBR Roughness/Metallic vs Specular/Gloss
To add on to the explanation(confusion?) of metallic: This is the way I'm used to working with PBR: 0 in metallic texture = Use a uniform standardized value to define your reflectivity curve: 1 in metallic texture = Fetch the value to be used to define your reflectivity curve from the Albedo texture. I.e. If you do define… -
Re: Optimization for VR PC project tips?
Material performance normally depends on the complexity of the math involved, amount of texture lookups, and screen space covered by the given material. Materials that uses a lot of texture samples are slow. Looping materials (parallax, noise, etc) are slow. Realtime noise is extremely slow, especially multi layer ones.… -
Shader help
I'm having trouble with a shader i've written. up until now everything seems to work the way i want it to work, and i'm happy with my progress. this is my first time writing a shader, and i've not got any programming or code background... so please bear with me. i'm just a character artist trying to expand his skillset! so… -
Shader - Kelemen Szirmay Kalos - Negative values
Hey peeps, Can anyone double check the Kelemen snippet I found, here? For some reason, it doesn't seem to be working as intended, I'm getting some nasty 'negative glowing artifacts' on my mesh when I apply. I'm trying to avoid a Beckmann texture lookup, instead trying a real-time thing, so it's not 100% nVidia approved,… -
Re: Witcher 3 Architectural Material in Unreal 4
@lele83 I'm not sure I understand what you suggest How would you use RVT to do texture lookups based on an index? In my understanding, RVT is basically a fancy and performant render target. The issue is in having many (potentially dozens) of different elements, all seperately unwrapped onto a tiling texture (meaning the… -
Re: Monthly Community Noob Challenge June 2014 (20)
Finished! :D ! Here's the link to my portfolio page with several close ups and a wireframe of the whole scene. http://scottmichaelh.cgsociety.org/art/3ds-max-mudbox-photoshop-udk-meshlab-bunker-architecture-3d-1200493 I had several lightmap issues and had never done reflections in a UDK. I made a slight adjustment with the… -
Re: [UE4] ~ Interactable grass, how do I make it react to every PC and NPC?
No. Use a texture and a loop. Looping the pixels of a 1d texture would look like this in a custom node: Inputs of the custom node: Tex - Your texture XRes - Texture resolution The actual code: float StepSize = 1/XRes; for(int i; i<XRes; i++) { float3 RawValueFromTex = Texture2DSample(Tex,TexSampler, float2(StepSize * i,…
