Re: UDK - Material - Custom Lighting and Diffuse - Half Vectors not working?
Diffuse texture goes to CustomLightingDiffuse slot. Then just use a dot product of light vector and surface normal, clamp it to 0-1 range, multiply with diffuse texture and plug it in CustomLighting slot. Now since you're doing half lambert you just have to alter/bias the value that dot product produces. Here's an example… -
Re: Vertex Weighting with CAT rigs
It defaults to blend weights and if you want to actually paint weights you need to turn that off, its a check box just under the paint weight button. With it on, it attempts to smooth out the area under the brush with a bias toward the selected bone. When painting you want to use the shortcuts I listed to control the brush… -
Shader development question
I want the shader to behave like in the diagram above. Is it possible to make shader that bias core shadows towards the shadow side of forms? I don't know anything about how to write a shader nor what program to use though. I just wanna know if someone has done something like this in UE4 or other engine. As I think if I… -
Re: New PC build
The £90 difference in no way justifies the small difference between the to. I would instead save that money for whatever or save it and upgrade parts sooner than you would do in future if something very substantial comes along. Going for the "lastest" in my opinion does not justify spending more. I may also be a bit bias… -
Floating Geometry not showing up in 3ds Max
Im having trouble with getting my floating geometry to show up during the bake...Just wondering if I was missing something. I tried using the cage as well and setting it to cover my floating geos but no luck. Tried not using the cage and increasing offset as well. I think what i'm missing is the bias setting somewhere.… -
Re: substance painter vs 3d coat and Hand Painted Texturing
Absolutely possible to get the same results, 3dcoat has better performance and a quicker setup but less features (for painting and shading). So if your computer is high performance and you already know how to use Substance Painter then there really won't be much of a difference. I still think working between PS and 3dcoat… -
Re: Microscratches in PBR
Yes, that's what I meant with mip mapping. The mip mapping process blurs the scratchmap, and it looks more like molten ice with scratches now. You would need to adjust the mip bias in your GPU driver or try saving the texture without mips (if that would work in UE4) This is one of those things in realtime rendering that's… -
Re: Lifeguard house (UE4)
It's called Peter pan'ing you should be able to fix it with the shadow bias but that can often cause other issues with shadow acne. Unfortunately it's just a something you have to live with/tune aswell as you can with shadow maps only fixable really through brute force of having enough resolution. You could bring in the… -
Re: LPC vol2 #3 - Time Machine!
Oh yeah, and here's where I'm up to atm. Not sure if i wanna use spec maps because I've textured so many light bias highlights. Still need to finish up the skin, and tidy up some bits of texture here and there. And are we allowed to vertex light for final renders? If not I'll have to sort out baking the paint as best as… -
Re: The Honest Feedback Thread
Ok so here is a little proportion bias test. I took a Kr0nPrinz Picture and cut out the eyes nose and mouth, and jumbled up the locations. I then tried to place them back where they were supposed to go from memory. I really did overestimate the distances! So i think this is probably my biggest issue. EDIT: so i tried…
