Normal Map Bake Problem

nick2730

Hey guys im using max 2012. Im trying to do a simple bake of a grate on to a server. The server has more details but i simplified it to i can figure out what is going on. Anytime i bake with projection map enabled i get ray miss checks everywhere and i dont understand why.

Its a simple object, the grate in on the front side but yet everything shows ray miss errors.

You actually added the highpoly as a reference mesh in the projection modifier right?

I can't really tell but it looks like you forgot to un-hide your High Poly? And did you add it to the list of things for the cage to pick up?

nick2730

yes its added in the projection modifier

i added more pics, its just a simple grate in front of the main object nothing huge

Even if its hidden, why would the rest of the UV map show raycheck miss? There is nothing there just the object

The rays from the cage have to hit something or you are going to get a ray miss error. Check this out and scroll to working with cages, if there is no HP then there will be no normal information.

Am I missing something or do you not have a high poly version of the CASE, only the grate? If there's no high poly case there's nothing for the rays to hit so it shows a ray miss. The map looks correct to me.

If you want the low poly to block rays, you can check Include Working Model in the Projection Options.

working model worked, never done just details from an object before. Knew i was missing something easy. Thanks
