Re: 186 grey instead of 128 grey got any tips for authoring textures this way?
what? this is all rubbish... using 186 grey as your mid-point is if you want to try to author your texture in a linear format, in photoshop, which is almost impossible. the "best" way to do it, is to use a curve adjustment as farfarer pointed out. just make sure your top layer is that curve adjustment and anything you do… -

Hello guys, the game engine does not darken anything. Unreal 4 is 1:1 between Photoshop and in game, if you make any colour in Photoshop it gets into Unreal exactly how you see it. You can test this by importing the texture as sRGB on and then switching the viewport to base colour mode and sampling the colour. If you make… -

Hi guys, we're currently learning about the whole gamma correct pipeline for UE4 and how you should author your textures at 186 grey in Photoshop to give the lighting engine better more physical values to work with so it can absorb and bounce light correctly. I'm referencing these two pages in case anyone is wondering.… -

Bake the textures in 8-bit 2.2 gamma (most 3d packages can) or 16-bit and then change the gamma in photoshop, or else you're just stretching the existing information. About your concerns, making the texture brighter isn't to make it more noticeable it's to linearize the data so the same amount of information exists on all… -

We're using UE4 so everything is corrected for us with the sRGB tick box for albedo textures. But on top of that we now also have to use mid grey of 186, unless we've totally misinterpreted the Epic documentation. I don't think so though. Also we've tested that in fact whatever colour you make in Photoshop will get into… -
Re: 186 grey instead of 128 grey got any tips for authoring textures this way?
Hey, Sorry for bringing this thread back, but I've been having trouble with this recently. I'm trying to author colour overlay maps that get overlaid on top of a base colour via a Overlay Node in UE4 material editor. The trouble I'm having is that UE4 Overlay node does in fact seem to use 186 grey as the midpoint. Anyone… -

You could always throw a Curves adjustment layer on top of everything, with an input of 127/output of 186? -
Re: 186 grey instead of 128 grey got any tips for authoring textures this way?
Generally there are settings these days in the engine to gamma correct the textures, so you shouldn't need to do this. Ticking the sRGB checkbox in the texture properties should mean the texture is sampled correctly (you generally only want colour textures to have this ticked because you want everything else to come… -
Re: 186 grey instead of 128 grey got any tips for authoring textures this way?
Hey thanks for bringing this thread back I had forgotten about it. I did a lot of research and found answers to my question, but forgot to post back here. So first, Beddall, yes we had that same problem at work with the overlay method you are talking about. There is a fix for it, but I don't know what it is. One of our…
