Been there done that. Actually I think bluring it out could help, I did it on previous images but for performance sake I didn't included separate bump to frame or tire texture.. So I'll try and let you know ! Though I finished ~ 80% with this bike, nice animation could be done, but rendering time would kill me. Here it is: https://www.lubyslaurynas.com/bmxbike.php what people fail to reaise is that the actual color that causes bump is the grey values between the white and the black. If you give the bump map a slight blur in PS it will soften it a little. Then adjust the bump value as needed. As the default is always 1 try dropping the values to some like .05 Jay
