View Full Version : Create normal map with curved edges for low poly model?

I saw a chap using Max yesterday, and he created a normal map from a high res poly mesh, which included radiused corners. When he then applied this normal map to a low poly mesh for us in Unity, where the edges were a standard 90 degrees, they still appeared as curved in rendering, due to the normal maps. Is there any way to create this effect (normal map) with LightWave?

Sounds like displacement.. normal maps don't make a surface appear curved. Especially up close. But then again I might over-interpret what you are saying. Smaller details might very well appear curved from a distance, but that would be the same on any 3d tool.

In LW is not easy and fast, just waste of time. This is matter of vertex normals and surface baking camera. You need also external plugin:

I highly recommand Substance Painter. It have great texture baker. I just created this what you want in a minute. SP reading wrog normals from LWO, that means you must use FBX. And you don't need cage mesh ;]

Also if you have Maya there is free plugin from Substance for baking:

Actually you can create a normalmap without a plugin, but it is cumbersome (to put it mildly) I think the normal map baking support is appalling to be perfectly honest. That is certainly something I want to see amended in the new version.
Anyway, the plugin is here:

Thanks guys - it sounds like Substance Painter might be the easiest option! I don't use Maya, unfortunately :(
