Yesterday we had a progress presentation, the feedbacks that is given to our texturing and modeling team so far so good. While we have to work more hard on our texure, specially for the bump and specular map. We still have a lots of model’s texture need to work on, that need to take lots of time. So we decide to set the dead line to week 9 to finished all the texture with approval from all the lectures.
As we realize, the normal map can not satisfy our requirement very well, some details on the model can not be perform by the map we bake in previous modeling stage. However we dont want to scrap them. When we used a nomal map, in a simple scanline render, I don’t know any ideas about using a nomal map and a standard alpha bump map together. The only thing I can imagine is probably we can convert the nomal map into the a heightmap. So I did some research.
Due to the research I found out we can combined normal map with bump map, but it is hard to realize by 3dsmax, most of the answer I found from internet was saying using maya and other software. For example, there is a new feature in Mudbox, which allow you straightly combined nomal map and greayscale bump. A second way is you can directly paint on nomal map, but this is more time consuming.
Another simple way is using software that can help for you to generate bump map, which is converting nomal map to bump map. That would be a lot more easier, although there would be some problems when you testing the bump, but you can easily fix it. The most common software that used to help generate bump map is Nvdia photoshop plugin, another is crazy bump. I am now using crazy bump for generating the bump and nomal map. It is specify in these function and vary hepful and handy.
