Transfer Stiches - High poly mesh uv to low poly mesh uv

[Vasanthakumar34300235f7kk]

Hi Guys,

I have a highpoly sofa model with stiching created in substance painter. Also I have a low poly version of that same sofa model, so the UV is differed from highpoly object. How can I use the same stiching layer to lowpoly model in substance painter?

OR  

If I am working in a wrong workflow, please share the correct methods to do one time stiching for both highpoly & lowpoly models 

Thanks,

Vasanth

Hello Vasanth,

You're working precisely with the expected workflow. You now simply have to bake (F8) your High Poly onto your Low Poly model, and the UVs don't even need to be the same.

Thanks for your reply.

I can understand what you have said (highpoly to lowpoly baking process), actually the stitching is drawn inside substance painter using stitch brush on uv of high poly model. How can I transer that stitching layer to uv of lowpoly model?

Oh, I though the stitches were made with the topology of the High Poly model. We usually work with Substance 3D Painter on the Low Poly, so the typical workflow would have been to add the LP to Substance Painter, bake the mesh maps with the HP, and then paint the stitches.

If you now want to transfer the texture from the High Poly to the Low Poly, it is a bit more complex. You can adapt the UV map from the LP to look similar to the HP one, so the texture would work on both models (this can usually be done automatically with most modeling software).

You can also use Substance 3D Designer to bake transfer a texture from a UV set to an other.

However, if the amount of work isn't too much, I would simply redo the stiches on the Low Poly model.

Thanks for your reply.

I have one more doubt. I need to stitch over the pillow model and its not have a smoother surface (ups and downs) so I can't stitch continuously. I can hold the shift button and click over the surface then stiches created from 'A' to 'B' position, then i try to make continous stitches from B to C but 'B' point not matched exactly, so each and every time need to click and match the previous position of the stich. Is there any way like pen tool path?
