Description

I'm not sure what's going on ,but the color seems washed out. I thought maybe it was something with the Armory PBR node ,but you can get the same results with just a image texture and diffuse node.

My texture

Armory results

If you add a gamma node between the texture and pbr node and set it to 2.5. This seems to give it some color back ,but makes it really dark in Blender.

I tried to upload a blend ,but I'm way over the size limit.

Research direction

Start by reproducing the washed-out result with the image texture and diffuse node, then compare it with the Blender texture and the gamma-node workaround shown in the report. Investigate the color-space handling around the Armory PBR node and image texture; done means the rendered texture matches the expected colors without requiring an ad hoc gamma adjustment.
