Hello can someone explain to me how to bump map and give me some tutorials i need to bump map the gun im working on but i dont know how?
apply material to your gun
inside unity change material’s properties to Bumped Diffuse
Choose texture and Normal map.
Normal maps can be generated using various tools to simulate bumps. Although they are imprecise, if that’s where you aim at. So instead you could model higher resolution of your low poly model (make it high poly) and use such tools as GPU meshmapper or sculpting tools (zBrush, Mudbox) to generate normals from high res on low res model.
I have made HD tutorial for this, but currently on 500MB bandwidth limit on my 3G, will try to upload them sunday evening, if i get fixed connection somewhere hopefully
Normal map. You want to get into the habit of calling it what it is. A bump map is something different and only used now in pre-rendered work.
Anyway how you create one depends on how you’re making your model. You can either bake details from a high polygon version onto the low poly in-game model via the package you’re using (google for tutorials), or you can draw them by hand as grayscale images and then convert them to normal maps either with a Photoshop plugin or through Unity (google for tutorials / check the Unity documentation).
Make sure your normal map matches and fits the texture and the UV coords, then add it to your material in the Normal Map slot. Providing you’ve got some lights in the scene, you’ll see the normal map in action.
Check out the demos on the site, the bootcamp demo and other examples to see how it’s done. There’s a lot of info out there and fitting whatever apps you’re using, for someone willing to do a quick search for it.
