Depth issues

Hey,

 

I have been playing around with 3D-Coat for the last couple of days and have been stymied at every turn (at least it feels that way).   :)   I'm probably being stupid on most of this stuff so feel free to call me on it.  Here is my list:

 

1) Surface mode using live clay with the noise functions.  Is there any way to keep it from adding more depth but still have the noise imprinted on the surface?  Do both a negative and positive displacement but keep the mid range depth the same as the original surface?  

 

2) Painting by depth range.  The height and cavity options don't work well, the height options don't work at all for me in the Linux version.  I would like to be able to specify a depth range that the paint tools would be limited by.  Is there any way?

 

3) Exporting displacement maps is very broken.   :(   Most of the options don't output anything but either a solid grey, or a completely transparent image (even if you do a PPP merge).  I think that has been the most frustrating part as it seems that everytime I think I have figured it out it changes on me.   :blink:   I did finally get it to work by choosing "Grey - based, not normalized".  If you choose "Zero level is grey"  you get displacement above grey but loose all of the displacement below grey. 

 

Anyway thanks for letting me rant.

Hi Jason!

 

 

Unfortunately there is a bug that is occurring more than it should. This used to be a very rare case. But the upside is, it's likely to be more reproducible and fixed now. :) There is already a Mantis report, if you wouldn't mind posting a confirmation. Here is the report:

Thanks Javis,

 

I put a note on the report.  I will check and see if there isn't another report on the height option and either add a note or put in a new mantis report for it.  I think my first issue is more of a feature request.

Indeed. Sorry, I was addressing issue 3.

 

 

Issue 1: You could do this with a stamp or stencil (stencil would be preferred), just make sure to clamp the whites at mid-level grey in PS before importing it as a stencil in 3DC. That should get what you want.

 

Issue 2: To clarify, you want to specifically place your painting to a certain topological level within the height/cavity? For example a cavity you might have is from 0-1, but you want to paint only in the .3-.4 range? Is this correct?

Thanks Javis,

 

Issue1 - I really like the noise functions in live clay, it's so nice to use.  :(  PS doesn't run on Linux, although I could try Gimp or Krita.

 

Issue2 - Yes exactly.  :)  The cavity functions do work great for cavity stuff, so I'm thinking that maybe the height functions might do what I want?  The problem is that the height functions have never worked for me on the Linux version.   If I'm remembering correctly (I need to double check to be sure) is that both of the height functions don't do anything no matter how you set the settings on them.   If  you use the preview window, one is always black, the other has some kind of strange inverse look to it.

Hi Jason!

 

Issue 1: Ah right, sorry. Yeah one of those tools should be able to do it too. Though I can't recall where that function would be, it's been so long since I used either.

 

Issue 2: Awesome, yeah that would make an incredible feature! 3DC is almost there with it, but when using the Depth Range as it is now, really just go from 0-whatever you specify. There's no way to control the range within. Sounds like a good feature for Mantis! You've already got my vote. :)
