When you have in the scene a static object and a real time light when you bake the lights the object apear flat shaded even so its been smooth shaded.
i set the barel to static and backed with a real time light.

set the entity shader to highest and see if that helps.

GameGuru lightmapping and smoothing groups do not blend well.

There is a setting in the setup.ini file that will change the smoothing angle during light mapping.

That's the limit of the current 'nasty' light mapper. You can try increasing the lightmap resolution settings in SETUP.INI for better smoother light mapped objects.

Actually I have found the problem is with the models normals and smoothing
groups. If you attach the model I will fix it and you can see the difference.
I have found that the light mapper works quite well if the smoothing groups
are correct. The problem is that most modeling programs do not make it easy
to create correct smoothing groups or loose them on export or import.

I probably should create a video on how to fix the smoothing groups, I could use your model
for the video.

@Stab: If you can recommend the 3D modeling tool you use to correct the smoothing groups of the barrel, I can give it a go and maybe produce a video. I have seen this artifact a few times but assumed it was the light mapper creating a lightmap texture slice too small to account for the light changes between polygons as the angle changes. Nice to know it can be solved with some improved normals

@TeamWolf
Ok, These are my results.
I have checked the barrel model and the normals and smoothing groups are
correct on all LOD meshes. I am unable to duplicate your results of a flat shaded
barrel in GG using Light mapping. See attached pic. I have no idea how you got GG
to flat shade the barrel.

@Lee
I use Fragmotion and Wings3d together. The concrete pipe is a GG model which does have
incorrect smoothing groups which would be good for a video. They can probably be fixed
in Blender and 3dsmax, but since I do not use them I am not sure of the process.
If you want I can still make a video using Fragmotion and Wings3d.

Use a static entity then light it up with real time light and then bake lights if you bake static with static or real time with real time the problem not acccurs

stab: the barrel in your picture is not light mapped , properly set to dynamic

Ok, Screenshot shows 1 dynamic and 1 static and light mapped.
I still do not get flat shaded. Team Wolf what version of GG are you using?

@Preben
You are correct in that screen shot barrel is dynamic. I attached wrong screen shot.

I did not add any lights in my tests. I think I misunderstood your first post.
Did you add a dynamic light? I will test that now.

@Stab : A quick video on "Fragmotion and Wings3d" would be awesome, and it could be the subject for one of my longer Twitch broadcasts as it will add some perspective on art pipelines into the mix rather than relying solely on default 'as is' media. If I could also list it on the GameGuru tutorials page as well, that would help future users too.

This is the shortest video I could make and still cover the subject. Lee you may post and list the video, and use it in any way you want. Hope this helps the GG users with the art pipeline.

@TeamWolf I can not seem to duplicate your results with that barrel?

Wow, that's the first time I've followed a tutorial on 3d modelling and it worked perfectly!

I was concerned that it was to long and maybe hard to follow.
I am assuming that you fixed a model in your screen shot, looks good.
I had found that smoothing groups were a mystery until I started using Wings3D.
I should probably should do a video on a more complex object that requires more manual tweaking.

Yep, I downloaded the HDU model from the NASA 3d model repository but it was not smooth (it is supposed to be an inflatable habitat), followed your tutorial and it now looks fab.

Now all I have to learn is how to create the _D,_N and _S maps from the rather low quality jpeg texture that came with it!

Hmm, I could do a video on that using Gimp.
Can you attach the jpeg?

Better than that I already converted it to png and improved it a bit in Gimp.

The model comes in two parts btw.

There are some pipes on the base (Part2) which could do with improving like you suggested above.

To the contrary, it is very well explained and good to follow
I just found out that i can also do this in Sketchup, have checked it in Fragmotion and the smoothinggroups are there.

Thanks for this tip.

I use blender the exported meshes i made have corected smoothing groops fragmotion show them smooth game guru show them smooth its when you lihtmap the the specular is flat shadet not the model if you completly remove specular even after lightmap the object is still fine but specular is a big thing you need to have specular in the scene.

@Stab : Awesome video, really well explained! Thanks for letting me post it to the community videos section of the GameGuru site: https://www.game-guru.com/tutorials/1030?page=2

I have received a few emails now for the "specular flat-sided issue" and will be looking at that today, but not before grabbing the latest Fragmotion and Wings tools, they look very cool indeed!!
