So I tried this tool regardless of it was originally developed by someone else, and it seems to work great, but only in the demo scene. Although it still looks good in other scenes, the difference is quite noticeable. I went through multiple settings in the scene to see why the changes were so drastic but could not find a reason why. Is there an explanation for this? Attached I can show some examples and it's quite drastic. There are 0 differences between the characters shader properties as it is literally a copy and paste of the model.
Here is a gif showing me play with the demo scene. I did this because the custom scene I will be using only has a directional light and no post processing outside of exposure and hdri sky. I did seem to see that the lighting may have been the issue, but not in the way I had imagined. It seems the large difference is the spot light called key, when that is turned off everything becomes scaly as you will see again. https://gyazo.com/f125a86280dfb16c10e3d2ecc9351946Now here is me copying the character and putting him in a new scene with only directional light https://gyazo.com/45b89dada221534acab0f66b57988a93I know it took me to the very end to see what I mean, but anytime there is the slightest bit of shadowing, the skin becomes very scaly and super bumpy and rough. Even the side that was lit was noticeably more rough than when in the demo scene. I want to point out that I did turn kevin into a game base lower poly model and the textures are set to 4K. This is because I wanted to see how it would look for a game ready model. I am also aware there is no diffusion profile in the scene which is why the eyes are pink, that is not what I was looking at. In short, why does this happen and is there a way to fix it? I think we can all agree that that is not very realistic to have you face suddenly change roughness and bumpiness due to light. I tried using the normal map and toning down the intensity but then makes other parts look crapy.
