tl;dr: When importing textures from Substance Designer into UE4 all textures look too washed out after they have been sampled except for the normal map which looks too dark.
The imported textures themselves look like the ones I export from Substance Designer. However, as can be seen from the attached images, the textures look wrong after sampling.
Most textures appear too washed out:
Except for the normal map which appears too dark:
I have tried exporting as both 8 bit and 16 bit with no difference. All textures are exported as targa in raw format except for the base color which is sRGB.
Strangely, if I turn on sRGB and change the sampler types from linear color and grayscale to color and grayscale the sampled textures look like the imported ones (even though they weren’t exported as sRGB):
I have been looking around the internet and several others seem to be having similar problems, however I have come across no solution that has worked for me.
Any help would be greatly appreciated!
