(3ds Max) Help With a baking issue.

StephenW

I'm having some issues with a bake of mine. When i bake a helix on my tube i get this strange bump information. I'm really stuck as to what could cause this issue and any help would be appreciated.

I have uploaded some images of the weird bump, the tube inside the helix in max and the tube itself to show there isn't anything wrong with it.
Any help at all is appreciated, thanks.

Pictures of the UV layout will help solve this problem, most likely.

I'm not a baking guru, so I can only offer some slightly educated guesses. 

UV doesn't seem to have any conflicts with the borders (it's by itself and not mirrored), so a projection issue is most probably the cause. I'd try first to adjust the relationship between the high and the low poly -- just run a few test bakes with both moved to more extreme positions to try and see how that effects that artifact. If you cannot solve like that, I'd dig a little deeper into the projection settings themselves. 

In that case, you'll need to post more about the program you are using, assuming you don't find the answer yourself and need further guidance.

Questions

• Is all your software (including OS and video drivers) up to date?
• What application are you baking with?
• What format are you exporting the bake to?
• Did you have a cage for your bake?
• If so, was it created after you verified the low poly looked ok?

The first thing I'd do is make the high and low res meshes much closer in size. If it still doesn't work after that post back here


Edit.  I'd also straighten those uvs out because theyre making me sad

How do you straighten UV's like that in 3DSMax? Is there a common method everyone uses or do you have to put it into something like Unfold3D?

If you make the tube out of a renderable spline it can generate nice straight uvs for you by ticking a box
