Statue project

This is a little project for a little contest at Facepunch Studios. I wanted to use this as an exercise in learning how to generate highpoly normal maps for a low poly model.

Here's what I've got so far...

Uv's:


But I hit a bit of a snag when it comes to the normal map...




I'm using Maya and Mudbox...anybody know what's going on here?

Jeremy Lindstrom

whats in the middle under the head in your uv layout thats all overlapped, you can't have any overlapping uv's in your normal map, it could be blowing it up.

Vailias

how are you transferring the normals? using maya, mudbox, or something else?

hey bud. Reset xforms on the model you are importing to project your normals to in mudbox. also make sure your UVs dont spread over the 0:1 uv space. (the square that you lay things out in). Its almost 100% your needing to reset xforms on the base model--that same thing happens to me almost every time.;)

Dekard: That ugly mess there is not a part of the original layout, that happened when I exported the wrong mesh for the hair.

Vailias: I'm using the texture baking option in Mudbox, then I just assign it within Maya.

Stoofoo: How do I go about resetting xforms?

In Maya that would be Delete all>by history and Freeze Transformations.

Thanks... I assume this means I'll need to resculpt?

I'll post progress tomorrow.

stoofoo

You dont need to resculpt. Just import the mesh into mudbox again. It should be in the exact same position as your original sculpt. When you do your projection, set the low res as the new model, and the high res as the sculpted mesh.;)

Okay...I went to edit> Delete all by type> History.

Then Modify> Freeze transformations with the boxes Translate, Rotate, and Scale checked.

I ended up with the exact same result. Even after a quick result...

Edit:

My workflow:

- I created the low poly model in Maya.
- I unwrapped the model in Maya.
- I exported the low poly mesh from Maya in obj format.
- I opened the model in Mudbox and sculpted it.
- I saved the Mud file then went to Operations> texture baking> new operation.

Then I started the operation.


Dunno if any of this helps.

Hey guys, I got it figured out-ish.
I'm using Xnormal to make my normal maps now.
Here's what I came up with:



I'll post updates when I have them...
