Help With Normal Map Errors [Image Heavy]

mats effect

Been having a hell of a time getting good results from my normal map and hopefully some people here can point me in the right direction. I am a little unsure at this point if its just a bad cage and lighting because I have been worked on it most of the day with out much more luck.

I have uploaded my normal map, the error read of out of from from max and the results I am getting in the view port using the xoliul shader. More or less my first proper normal map from a high poly so any help will be a big plus for me.

Thanks yet again guys.

A complex mesh like this should never be baked as a whole.

Keyframes, or edit poly modifier, either will do the job just fine.

If you want to watch how to explode a mesh for baking, check this video out:

Hey,

Yea its all exploded out more or less the same way as using the edit poly mod etc etc. Sorry should have said that to start with.

A shot of the explode and the high poly/low poly below. A major difference I note my self is the teeth down the middle of the track. I could not really do them in the low poly in such a way that gave me the tri count I needed, as this model is a uni assignment I have to worry about that stuff from their point of view.

Sorry if I'm preaching to the choir but, have you tried making the cage bigger? (I'm asking because I see some zfight between your LP and the Cage on that screenshot. Cage should be on top.

Hey, the Zfight you can see is the low poly and high poly over each other. Quickly tried pushing the cage quite far out but still had the same errors

Try reseting the xform on the initial mesh. I've seen the reset xform fixing really weird things before.

Not really any luck with that either. Considering re doing the entire explode and projections again, (with time I don't have ) but I really can'y work out what the issue is. I even tried just one object from it and still got odd errors with it.

The cage seems to be the problem...Try checking your UV's or “rogue” edges, maybe something flipped.

Yea think I am going to take it apart and bake bit by bit and see how I get on.

Off of what Runner said...

in the Uv Window you can go to Select > select inverted faces. You shouldn't be getting those bright green bits.

Thanks guys. I actually started with a re fit of the UV's them selves things like the wheels where not getting enough space. That should help for starters.

I shall update when I am done, hopefully with good news.

Best results I have been able to get. I just have no idea what's going on the most it does is add black lines around the edges.
