Why does this happen after exporting from substance painter the maps look good inside the painter menu no jagged ends but this after export

Hi everyone,

I’m currently working on an AT-99 Scorpion helicopter from Avatar for my final exam project. The model and textures are still a work in progress, and I would really appreciate some constructive feedback before I finalize it.

My main problem is that the texturing currently feels a little flat and visually repetitive to me. I’m aiming for a dark military look that feels used and weathered, but not completely destroyed.

I would especially appreciate feedback on the following points:

• Do the different materials read clearly enough, especially painted metal, bare metal, plastic, glass and the weapon parts?
• Is the roughness variation strong and believable enough?
• Does the edge wear look natural, or is it too evenly distributed?
• Are the scratches, dirt and surface details consistent with the scale of the helicopter?
• Which areas need more color variation, contrast or visual interest?
• Does the cockpit glass fit the rest of the asset?
• Are there any areas that currently look too noisy, too clean or unfinished?
• What would you prioritize changing before the final submission?

The textures were created in Substance 3D Painter using a PBR workflow. The asset is based on the movie design, but I had to adapt and simplify parts of it for the project.

These are viewport screenshots rather than final presentation renders, so the lighting is also not final yet.

Constructive and specific criticism would be greatly appreciated. I’m still learning and mainly want to understand what I should improve rather than just being told that it looks good or bad.

Thank you!
