extruded faces showing up light blue

[DOG-ZEBRA 0]

i posted this problem way back but i wasn't sure if the light blue came from chamfering or extruding. now through elimination i know its the latter. it seems it is the lighting in GR that causes the light blue because i examined the rifle in a dim alley and its texture was just as it should be. if anyone has experience with this i would love a little tip on correcting the problem. thanks

heres a link to the first topic months ago

btw thanks snow, but i didn't smooth any geometry

hmmm strange one. Have you checked the texture isn't set to self illuminated in the material editor?

Normally i would convert to an editable mesh after an operand be it Boolean, extrude, bend,taper etc. I've seen booleans create strange lighting effects, this is why i always convert to an editable mesh before texturing or smoothing.

Select your weapon, convert the whole mesh to an editable mesh, detach the problem polygons as a seperate mesh, UVW REMOVE that mesh and re map.

Convert to editable mesh(this will lock the UVW's) and reattach to the gun mesh.

well the discolored face was detached and the face mapped alone so i removed the map then reattached then retextured, but still the same. But! i got it sorted out though just i moment ago. the last time i posted this snow suggested maybe smoothing was the culprit but i didn't smooth it so i figured what the hell so i gave it an auto smooth and now the light blue is gone . Curious, i still would like to know what was going on but at least my problem is solved.

smoothing makes the lighting react more realistically, without smoothing lighting effects can show up as sharp lines/faces hightlighting the polygons/faces making up the mesh.Smoothing if you like spreads out the lighting effect making your mesh appear not so jagged and appear more realistic.

Hence your blue effect was caused by no smoothing being present on the mesh.

RSE recommended using smoothing group 2 for the GR engine, yet we debated recently as to how true this was as some people use auto smooth and other smooth groups with no problems.

this problem you are having looks a lot like the problem i was having with my AK model, like in the picture below:

that piece on the mag was also extruded, i fixed it by redoing that area with the line tool and extruding that, reskinned it and it worked perfectly.

maybe this will provide you with an answer to your problem

It's pretty simple really, any face on your model that doesn't have smoothing on it will show up brighter ingame than faces with smoothing. This is very evident if you use your model ingame without it's texture, parts with smoothing usually end up a dull grey while unsmoothed parts are just about white.

As far as I know just about any geometry you create in 3dsm has some form of base smoothing on it but as soon as you extrude the newly created faces are created without smoothing. Applying smoothing to those faces generally solves the problem.

Give me a few minutes and I'll export something quick just to highlight this.

that probly why i never seen this problem before myself,

i always apply autosmooth to parts of my model before i continue on even if the object doesnt need any smoothing...

and then do smooth groups if i have to.

the thing is that none of the model had any smoothing done.
