Every time i try to smooth this car that I exported from Roblox this happens
Before
After
I don’t know if i can fix this problem.
This might be a shading error due to imported vertex normals, which are colliding with Blender’s attempts to generically smooth the mesh. Try this…
In any case: You should ALWAYS provide an example .blend file with any support question. Otherwise you’re forcing uns all into a tiring (and possibly pointless) guessing game.
Also, maybe Normals Recalculation (in Edit Mode) will help you.
While in Edit poly mode
Hit W, select remove doubles
After that,
go to object mode
then hit space
then type in (Clear custom Normal )
then click on the only option
Problem solved.
I did you method but it solves half of my problem every time i try to use subdivision surf
it does this
I removed double vertices and did limited dissolve but nothing worked.
Blend file : http://www.pasteall.org/blend/42788
had to use this because upload keeps failing
I doubt this problem will be solved
That’s because your model was exported as many different boxes. I am just not familiar with Roblox, but maybe there are some options available when exporting from it (like a single peace)?
Ahh, move your light and camera to another layer.
select one piece of the car, hit CTRL+I to select all other pieces, not shift+click and reselect the first piece. CTRL+J to join as one object.
Then go into edit mode, select all CTRL+V and remove doubles, every section is separate, so even shaded smooth, the point where blocks of polys meet will be sharp.
EDIT: Scratch that, the model is rather a mess, in all honesty, I’d simply use this as a reference for retopology or even just b background model to work from.
