Texture brightness in unlit material

Hello,

My version 4.6.1.

Using texture in Texture sampler as emissive color in material. Shading model set to UNLIT.
sRGB flag in texture is ON. Texture has no alpha channel.

Texture in material preview looks darker than origianl texture. It looks darker in the gameplay too.

We need to match exact pixel color values in gameplay.

If i replace texture with constant white color(1,1,1) it looks darker and not completely white too.

Can you give some advice how to solve this?

PostProcess are all over it. I find it impossible to get a texture unchanged by any post-process in-game. The biggest change comes from the ToneMapper, but others post process plays too.

Unreal clamps bright pixels by default to prevent clipping to pure white. You can circumvent it, I’ve written the instructions here: White unlit not white? - #16 by Ari_Epic
