Tutorial o tom ako vytvorit Normal Mapu z hipoly modelu naimportovaneho do Zbrushu (napr z Mudboxu) – zaroven ako vymenit najnizsi lvl zo zbrushu za vlastny low poly model s UV a nasledne vygenerovanie Normal Mapy

1. Import Hipoly modelu do Zbrushu

(konkretne tento model ma okolo 2 mil. tris)

2. Vytvorenie rekonstrukcie modelu (velmi potrebne na to aby sme ziskali model s levelmi)

- rekonstrukcia modelu sa nachadza v zalozke Geometry – Reconstruct Subdiv (mne dovolilo urobit iba do najnizsieho lvl kde model ma 31 tis tris) – velmi podstatna vec: Pri generovani treba aby bol model v najnizsom lvl

3. UV problem

- po rekonstrukcii modelu mozme generovat Normal Mapu

- ale po stlaceni tlacitka ZMapper rev-E sa moze vyskytnut problem s UV (vid obrazok)

4. Riesenie UV problemu

- riesenie je velmi jednoduche, staci stlacit tlacitko GUVTiles

5. Capture Current Mesh

- Capture Current Mesh nam sluzi na to aby sme v dalsom kroku mohli vymenit najnizsi lvl za nas low poly model s UV

- takze po stlaceni ZMapper rev-E v zalozke Projection stlacime Capture Current Mesh

6. Delete Higher Subdiv Level

- v zalozke Geometry stlacime na tlacitko Del Higher, tym zmazeme vyzsie levely

7. Import Low Poly Mesh with UV

- teraz uz len stac v zalozke Import naimportovat nas Low Poly model s urobenym UV

8. Create Projected NormalMap

- teraz sa uz staci iba vratit do ZMapper rev-E a stlacit tlacitko Create Projected NormalMap

9. Raycasting Max Scan Distance

- ako vidime boli tam nejake errory, takze teraz sa staci uz len pohrat s hodnotou Raycasting Max Scan Distance v zalozke Misc a znova to pregenerovat

10. And this is the end of this tutorial

- tu su este nejake screenshoty… texturka ma rozlisenie 2048×2048

- dufam ze tutorial splni to kvoli comu bol pisany..

- dakujem
