Joint treatment:
1, the existence of seams is inevitable, and seams can only be located in blind spots or places that are rarely seen.
2. If there is no map, only the UV seam is invisible, which means that the seam appears because the colors on both sides of the seam are different in the map ... So when drawing a map in Photoshop, we should pay attention to the consistency of color control on both sides of the seam.
3. You can use BodyPaint to draw the map, and the projection drawing in BodyPaint can directly draw the images on both sides of the seam at the same time, which is easy to control. However, the accuracy of BodyPaint is not high enough, and the layer mode is single, which has some conflicts with Photoshop. Therefore, it is suggested to draw approximate shadows in BodyPaint and process the seams, and then import them into Photoshop for final drawing and processing, superimposing texture maps and other operations. ...
4. In fact, you can also use the cloning tool in BodyPaint to clone texture maps to reduce seam problems. ...
5. The most difficult thing to deal with is the combination of normal maps ... but it can also be handled in BodyPaint. The channels R, G, B, G and B are imported into BodyPaint and drawn by projection for three times.
