[Unreal 4.12.5] Sample grundge map gets darker with each LERP connection [SOLVED]
Issue I'm trying to composite a bunch of grunge details together. However, my final result looked almost... empty. It's as if almost all of the detail I added just didn't show up. I thought I hooked up the nodes wrong. I hooked up the nodes correctly, but I still had this error. Normally in substance designer I can take… -

Well, if you think of layering these blends you can get what I think you're after. You can also use whatever sort of alpha you want doesn't have to be 1 bit. Something like this: You have to think of the order which these things blend, I emulated what you had in your graph which is dirt over the base, then light, then… -
Re: [Unreal 4.12.5] Sample grundge map gets darker with each LERP connection [SOLVED]
You would have multiple texture sampler nodes (since it's the same texture map it isn't like having 4 different textures) and you use a texcoord node input into the UV slot of each texture sample. You can manipulate the the texcoord node properties directly for tiling, but that node can't be exposed via parameters, so the… -

No they can be in the same map, but you would have multiple texture sample nodes to tile each channel independently. Basically instances of the same texture map. Under the hood it would count as a single texture sample to the sample limit, even though you have multiple texture sample nodes. -

I see. I guess it could work if I use alphas with absolute values. I could make it work with a CheapContrast node. But is it possible to blend them as if it was a Blend/Copy node like in Substance? I'd prefer my alphas keep their translucency but not get killed off over generations. -
Re: [Unreal 4.12.5] Sample grundge map gets darker with each LERP connection [SOLVED]
is it possible to make a really quick and dirty example? I thought that's what I was doing but the texture sample node is giving me a float error. Even after rebuilding the mask into 4 vectors. -

I don't really see the point in re-building the texture with the different tiling, only reason I could think of is for organization purposes but you are just adding unnecessary instructions. Each texture sample is an instance of the same texture 1st being tiled twice, 2nd 3 times, and 3rd 4 times. Also different channels…
