I apologize for asking this, but i've looked ALL over the forums and I've fiddle with the app for hours and hours and just can't get it to export a proper displacement map and so I'm just curious what I'm doing wrong.... Here's the case :
-i've got a voxel model
-i've got a low poly model created in another app.
when I import the low poly model, it's lying exactly on top of the voxel model, so it's in the correct position and it's definitely bringing in the uvs with no problem, so those two important necessities are working fine... Here's the techniques i've tried and so far all have failed.
1 :
-load voxel VB scene
-go to retopo view
-fire toolbar-->retopo-->import and choose my low poly model
-fire toolbar-->retopo-->merge into scene per pixel
-click on paint tab
-fire toolbar-->texture baking tool and tell it to export a disp map.
When I do this, the disp map does get exported, but it's mostly covered in a flat grey and it looks like it's tracing to both the low poly and high poly models and that's of course, something you don't want it to do... I want it to not trace and hit the low poly model, of course... Also, if I try to export out a normal map using this same texture baking menu, it'll be just as error prone as the displacement map, so obviously I'm doing something wrong.
2 :
-load voxel VB scene
-go to retopo view
-fire toolbar-->retopo-->import and choose my low poly model
-fire toolbar-->retopo-->bake texture and bake the disp
When I click ok, nothing happens. (so apparently, the part of the application that's expecting a low poly model isn't actually seeing the retopo one..??)
3 :
-load voxel VB scene
-go to paint view
-fire toolbar-->file-->import-->model for pixel painting
I was thinking that importing the model through the retopo menu might be what was breaking the disp bake because it was thus accidentally storing the low poly model in the scene twice somehow, so I figured I'd try this instead, but this is obviously wrong because if I use that import feature, it deletes all the voxel data from the scene.
One last note.. I have successfully generated a normal map before, but it's not from using the texture baking tool. The texture baking tool has two problems. A : it's tracing to both the LP and HP models and that's wrong. B : it's writing out a world space normal map, even though I'm explicitly telling it to write out a tangentspace normal map. So either I'm completely confused, or that texture baking tool seems very broken. What DOES work properly is if I press the toolbar-->retopo-->merge for pixelpainting with normal map button. that creates an error free tangentspace normal map... (but of course, it doesn't create any displacement maps)
So what am I doing wrong? ...and thanks in advance....
ps.the official docs probably need to be updated because I couldn't find any useful information on this topic there or anywhere in any of the forums.
pps. btw, this app's just beyond amazing... I've been in the computer art industry for almost 13 years now and getting to sculpt in voxels blows my mind..
