baking high poly details to low poly model help

[colpolstudios]

Hi, i have followed this tutorial

Axe: blender cookie: http://cgcookie.com/blender/2010/01/16/creating-an-axe-part-1/

I copied the high poly axe and then made a low poly version.

high poly axe layer 3, low poly axe layer 1.

Here is the link to the .blend and a image of the normals when baked : https://www.box.com/s/e8abd33edfd607976d07

What i am trying to do is.

bake the high detail from the high poly axe to the low poly axe.

I have both versions unwrapped and plan to complete the materials on the high poly version and bake these to the low poly version.

last: import the low poly axe into unity as a test

I appricate any help you can offer thank you

Hi again I have been digging around and found a lot of requests on this topic. SORRY!!

I think the issue is with the internal faces inside the axe mostly at the top / bottom of the axe blade.

I have removed the offending ones in the loy poly axe and un-wrapped again, this looks much better now!!

I am going to do the same with the high poly axe, hey if all else fails i can always re download and start over.

SORRY again for posting on such a well coved topic.

But I still appricate any help you may have to offer.

Thank you for your time

I have managed to solve most of my issues, however one major one remains.

I could not insert the image so here is a link to it : https://www.box.com/s/c26706001e82bc1f7049

Please note : There is a issue with the normals on the rear of the axe.

It seems the issue is the faces at the rear of the axe blade, just the outmost edges.

If some one would be kind enough to take a look at the .blend and possibly help.

I have updated the folder with the new updated version.

Here is the link to the .blend : https://www.box.com/s/e8abd33edfd607976d07

I have updated the file again: https://www.box.com/s/53f694abb92745fd62b1

New normal map applied to the low poly axe.

hopefully this is at least better ?

Thank you for your time

Hi again, well its good to talk even if no one will help ??

I got as far as adding the normal map to the low poly axe.

I added this as a material and forgot the copy also had this, bummer!!

I then set about adding a texture map, of course i forgot (only one material slot was in use)

Now i have to start over.

Hey now i am really glad i had saved the download.

I have to say the learning curve for me has been very hard.

As a begginner!!!

I don’t know if you need help, as i’m unsure what is your question, but loading your last upload , i noticed you didn’t packed your normal map , so i can’t check what is your problem with it.

But looking at the settings, you may need some tweaks.

At the Baking panel, you have the margin set to 2 (the default) , it’s bad because with a margin set only to 2, you’ll be able to spot the “seams” when looking at your axe from some distance.
Increase the margin to 5 or 6 to be sure the visible seams problem do not occur (and why it’s a good idea to have in the UV some distance between the islands).
I’m not sure of the minimum value one should use at that Margin setting to be sure the seams never appear at some distance, but i always found 5 or 6 to be good enough.

Then in your texture panel there’s a “Image Sampling” tab, in it there is a “Normal Map” button that is not enabled by default, enable it (and you have not enabled it),
Your normal map will be displayed much better when rendering if you enable this.

Hi Sanctuary, many thanks for your help.

I manged to apply the normal map correctly this time and also baked the textures from the high poly axe to the low poly axe.

I packed the files used into the .blend : sorry i did not know i needed to do this.

File updated with a new file: https://www.box.com/s/e8abd33edfd607976d07

I also incuded the unity package.

This is my first ever attemp at texturing or creating the unity package.

There was only one issue the normal map had to be “fixed” inside unity.

Would you mind please taking a look for improvements thoughts or comments.

Thankyou again for your time and help.

Is the axe with how you configured it working perfectly in unity ?
I’m asking, because i noticed that you made 2 materials for it, one for the diffuse and one for the normal.

It seems odd to me, as if i click Render, the material that has the diffuse does not appear in the rendering, only the material with the normal (that is listed in 1st) is actually existing in it.
The only way i see the normal and the diffuse working is to use 1 material and give that material the 2 textures :

Is this 2 separate material for the normal and the diffuse a requirement for your Unity export ?

Other than that , i don’t see any obvious problem, and the diffuse+normal looks quite nice.

[colpolstudios]

Thanks.

In unity I am using bumped diffuse, you apply the normal to the normalmap section.

you apply the axe-texturemap to the base (RGB) section.

How do I use one material and give that material both textures ?

[Sanctuary]

I’m not familiar with Unity, so it may then not be usefull to keep your textures under the same material i don’t know how the export works for it, but it’s usefull to keep diffuse, normals, bump, etc… under the same material if you want to render your model.

The same way you added the 1st texture, let’s say you have a material, and have a diffuse texture already :

You want to add your normal map, so you select a slot under the 1st texture

then you press “New”

After that you configure the texture to your needs.

Thankyou so much!!!

I could use some help with the lighting as the render “my first” is very poor:(

Altough i have tried a number of times i can not attach any images, nothing happens.

I managed to set up some good lighting and got a very good render.

Thank you very much for all of your help
