image colour variation query

Morning

I'm getting some funny changes with the appearance of textures.. i'll try and explain...


Setup 1

image node piped straight into Beauty - image is represented exactly as the original jpeg.


Setup 2

image node into base colour of a standard material

+ image node with alpha into cutout opacity channel

then this goes into the Beauty.


For setup 2 there is an subtle desaturation of the image even though the standard surface parameters (as far as i can see are zero'd or max'ed out)


So.. Is there a trick to getting the image output in Setup 2 to be accurate

or

is there another way to add an alpha cutout when using just the image node direct to beauty.


Thanks for any thoughts

Alex

If you pipe the image into the beauty, you basically get an emissive surface, affected by no lights. While connecting the texture to the base color of a standard shader it represents a diffuse layer affected by the lighting. That's the difference between the two setups.

If you really need an emissive surface/look, you can connect the texture to the emission color input of the standard surface shader and turn off base and specular.
