Normal Map Noob Needs Help 3ds max 8

[Razorb]

Ok im bassicly trying to render a normal map in 3ds max 8 using a high poly model over my low poly one :o ! ive done it before on a super super simple model and it worked fine ! now ive made something else to try it with and when i render the normal map i get loads of problems. 1st being the ugly Red and stuff all over the normal flat! secondly is when i applied that normal map to my low poly ( just to check it out ) i got what u see in the second image heh...

The red pixels are "ray miss" areas, where the rays from the low poly have missed the high poly. It also looks like from the wireframe overlay that you have overlapping UVs. You need to move all but one face's worth of UVs 1 unit outside of the 0-1 UV square, so that there are no overlapping faces when you render. You should increase your ray distance, or push your cage out further so it doesn't miss the high poly.

The 2nd image looks like it's not using any lights. Try to reset Xforms and collapse, restart 3ds max, and try remaking your shader using normal bump instead of metalbump.

Look over this tutorial for more specifics. http://www.poopinmymouth.com/tutorial/normal_workflow.htm

Thanks mate ! explained alot i know all about the projection cage n stuff now

as for the 2nd image.. that only happens when i enable that DX option for real time viewing and i did use normal bump ...

Ive started off with something more simple to get a hang of things ! and yea its pretty crap too ;o so its nice ive got alot to learn ! and im starting to really enjoy it ! will do another when i wake up tomorrow :)

Thanks again Ben is it ? :O heh really appreciate the time it takes to write up some help and do the great tutorials that u do :) thanks

I have tried to created irregular shaped models by using line in 3ds Max. The result comes out was hollow models when view from angles. Could someone please teach me to make a complete 3d solid with line function?
