  10. realtime AO

    Sorry for necroing.
    I can suggest one tehnique we developed for our game engine, pretty fast and ultra accurate in the avilable tech level (not HBAO)

    If interesed i can share it privatly via skype or PM

  11. Tangent Space Calculation via per-triangle to per-vertex space co-respondence

    in Feature requests

    Posted

    In my research normal maping and tangent space calcs i found interesting method to control the artifactless and very accurate TS generation via per-triangle to per-vertex tangent space co-respondence, i think this method can be added to the TS Calculation algo list in the 3Dc. It can produce 16bit normals maps that is vry usefull in the modern PBR pipeline (via BC5/ATI2n/3Dc for sure). This method is used in Cryteck Polybump software.

  12. Complex mixed Mirrored\nonemirrored UV Baking

    in Feature requests

    Posted

    I dont know does any other 3Dc users met this issue via their workflow but i want to suggest some ideas that used commonly in most baking resolves.

    In 3Dc useing the overlapped and mirrored UVs cause to cross-bleed artifacts while baking from the material when the information can bleed from the co-coresponded triangles truely randomly and than in the game engine this mesh will have a lot of seams and so on. If the mesh have a shared islands with a lot of overlaps while baking it will be a lot of artifacts too and the worldspace map will be absolutly damaged and not readable. Because of long work with complex meshes the symetry partialy broken in destructive way and any new bake will cause a pain and artifacts.

    Some examples:

    and result of overlaping:

    Many of game engines doesnt support the mirrored UVs and in this way to fix this issue goes to the real pain and waste of time. So the first resolve of this problem is use a "One Unit offset", when user are able to shift selected islands on one U/V unit in UVW-space to prevent the Baker algo work with this islands (Bakers only works with UVW 0 layer, but engines read whole set), in any case this offseted UVs will share same texture data from UV 0 in any game/3D engine i know, for the Unreal Engine this solution is only possible with mirrored/overlapped islands.

    I hope this feature will be added in UV and Retopo rooms and will save a lot of nerves and time for 3Dc Users.

    Hooked devil model for game Kenshi is done )

    Here is sketchfab turnable

    Now i workin of the different model for another game... and met the problem to bake a Material-Id map... The model is too complex to handpain the maps.... so im stunned a little

    I know it's not on, but he would be a perfect "Carrot King" especially if there were arabesques above hit head/shoulders.

    Bwahaha, yeah )

     

    I dig the concept art made by Jane, you and those in the studio are very talented!

    Thx a lot ) i will say her)
