texture baking question

[wilson66]

I'm evaluating the workflows in 3DCoat and how to use them for my purposes (texturing mainly of 3d animated characters). I like it a lot to work in 3DCoat, created a highres character using the surface tools, retopologized it, and painted textures for the new lowres mesh after baking the normal and occlusion maps.

 

Everything is working great, but I have a question concerning workflow. I already tried to create a retopology mesh, then go back to the Sculpt tab and add additional details to the character, adjust the retopology and bake out the maps again. So far it works.

 

But what happens when I want to add additional details in Sculpt mode AFTER I have already painted textures for the retopology lowres mesh? The UV layout changes, can I transfer/ bake the textures I already created to that new UV layout so I only need to paint the details I added afterwards? How?

 

EDIT: I see that it works using the Retopo Room -> Bake -> Bake Texture tool, it seems to be an obsolete tool though. Is there a better way? Preserving the paint layers from the Paint Room won't be possible either way, right?

2 method i was using

--------------------------

new project

paint Room

import model for ppp = your old painted model

 

retopo room

Retopo > import = your new retopo lowres mesh

 

Bake

--------------------------

Old method -deprecated-

retopo room

Bake > bake texture

Thanks carlosan, that worked.

 

I always seem to get these kind of grey, square artifacts in the baked color map though:

 

 

You would think that this is due to too low baking scan settings. I am able to reduce them by increasing the 'Scan Depth outside the Object' setting in the baking menu, but although there is more than enough room between the object and the outer shell (no interpenetration happening), I am unable to eliminate those artifacts completely. Adjusting the 'Snapping Method' in the baking menu ('snap to closest along normal' or 'snap to outer surface') makes no visible difference.

 

Any hints?

hmmmm nope...

 

just to test try

0.5

0.5

 

adding spheres of influence in grey zones

 

and remember to hide the old object in paint room after bake

and remember to hide the old object in paint room after bake

 

I will test again, thanks. And the old object is hidden in the paint room of course, the grey areas are not the second object poking through, but actually pixels baked into the texture. 

 

EDIT:

 

Everything works OK now. I adjusted the scan settings to high values (inside/ outside object 10 / 10), and the artifacts have disappeared.

 

I'm very pleased how all this works out! Thanks again for your help.
