Blending Base color maps colour discrepency

Hi All, 

 

I have exported textureres (two Textures Sets) from Painter that I am blending together in Designer.

 

I have an issue, that the luminances/brightness of my Base Color Map. After the Material Blend node, it appears darker (all other maps are fine). I have tried all blending modes for the Base Color with no success. Both Base Color maps are exported from Painter with the same settings. 

 

I have Inputs for all maps connected to a Material Blend, only the Normals maps are first combined using the Normal Combine node.

 

I would really appreciate any help and suggestions.

 

Many thanks

Your first Base Color image seems to be a plane grey color with a small pattern in a lighter tone. I guess you want to add the light tone pattern to the second Base Color, but when blending the two maps together the entire map will blend with the other (not only the pattern). Therefore, the plane grey will also have an impact on the rest of your map, turning it darker (depending on the blending mode). In fact, you can also see the same behavior in your Roughness map.

 

To add specificly the pattern, you can turn the rest of your map black (not the pattern), and set the blending mode to Add (linear dodge). That should be easily done with an Histogram scan Node.

 

Best regards,

Hello @AWP_0219,

 

Could you be more specific on your goal? How the second Base Color looks?

Blending two Base Color together will obviously alter the output of the map.

Hi Cyril, 

 

Thanks for responding. The two sets of maps share them same UV's. I needed to seperate them to assist in baking in Painter, but I wish to combine them into one set of texture maps - that is my goal. Upto now, all seems to be working, it is just the Base Color that changes its brightness. In the previous post I attached a before/after blend images.

 

Many thanks
