Can't find my mistake. Workflow/3D Coat.

robinmcdiarmid

Hi guys, please take a look at these images and tell me where I went wrong. I had no problems until it came to creating and exporting the albedo from 3D Coat.

Workflow: LP & UV (Maya), HP (Zbrush), Bake (xNormal), Texture (3D Coat).
Below are the LP and HPs, a combo of LP UV, normal and AO, and then the Albedo from 3D Coat.

As far as i can see your abledo is painted on different UVs. Honestly it is hard to say where you made your mistake. Maybe you had 2 versions of low poly with different UVs?
Those on the bottom have most of the UDIM empty - it looks like dafault UVs.
I don't think it is software mistake - those UVs are totally different

Is there any way of bringing the correct LP UVs into 3D Coat and onto the painted model? If not, do you know how I might be able to bring in the HP again but with the correct UVs? (The HP is sculpted directly from the original LP)

You have Low poly version with UVs, correct?
On that Low poly version you baked maps from HP using xNormal, correct?
HP don't need UVs - it is used only for baking (well, most of the time).
If so, then in 3d coat you need to open low poly (for paint UV mapped mesh per-pixel, the same low poly you used for map baking) and in textures menu: import baked maps (usially it is AO, curvature and normal map, at least for me, depending on the workflow you have/need those might be different). They all will be imported on seperate layers, then you have to paint texture again.
In my opinion you made a mistake - you used different LP version for baking maps and different for painting the texture. This is only my specilation, cause you have 2 totally different UVs.

Generaly simplest workflow is:
HP mesh -> Retopology (LP) -> UV -> baking maps -> paint texture
You can do the opposite - take LP mesh duplicate it, subdivide and add manually small scratches and dents and all that - everything that won't change silhouette too much so you don't have to modify Low Poly.

Is there a good workflow tutorial out there that can show me how to start with a HP and get it down to a low poly after?

SebastianBielecki

Workflow is pretty simple -  create your high poly model first and then retopology it I don't use 3dCoat a lot - i'm making retopology in max mostly.
Your workflow was good - you just mixed models

Okay thanks, I thought I only had 1 LP and the cage, I must have used an old export before uvs or something haha, thanks a lot for your help friend!

happy to help, if you' still have problems let me know!
