Issue #1 - Model explodes

Steps to re create:


  1. Select any model.
  2. Create a layer and turn on record at highest level
  3. Move down to lowest sub d level
  4. Make an edit
  5. Change layer intensity slider to 0.
  6. Go back up to the highest sub d level of tool
  7. Change layer intensity slider to
  8. Model will explode.

Issue #2 - Layer artifacts left over even when layer intensity is at zero. This issue has been in zbrush since the implementation of layers. Sets to re create:


  1. Select any model.
  2. Create a layer and turn on record at highest level
  3. Make an edit
  4. Go to the lowest sub d level.
  5. Change layer intensity slider to 0.
  6. Go back up to the highest sub d level of tool
  7. There will be artifacts left over from the layer even though the layer intensity is at 0.

Issue #3 - Toggling layer visibility or changing layer intensity while not at highest sub d lavel causes corruption. Sets to re create:


  1. Select any model.
  2. Create a layer and turn on record at highest level
  3. Make an edit
  4. Go to the lowest sub d level.
  5. turn off the eye indicator on the layer
  6. Go back up to the highest sub d level of tool
  7. There will be artifacts left over from the layer even though the eye is off

Furthermore, I have found that doing any of the following things while not at the highest sub d level will produce drastic artifacts on the model, rendering layers useless.


  1. Changing the layer intensity slider at any level but at the highest sub d level
  2. Using the timeline to adjust layer intensity at any level but the highest sub d level.
  3. Turning the layer visibility on or off at any sub d level but the highest sub d level.


An easy fix for these issues (if Pixologic can’t fix the bugs) is simply to disable turning a layer on or off or adjusting a layer intensity while the tool is not at its highest sub d level. Simply grey out the layer eye icon and the layer intensity slider. That would fix all of these issues. :wink:

Thanks for your help! sadly i couldnt fix the problem.

its a pity that this guys dont fix those old bugs.

Layers are completely useable, there are just a few caveats when using them:

1. Never ever turn a layer’s visibility on or off while you aren’t at the highest sub d level.
2. Never ever use the bottom layer adjust slider. Basically if your main layer slider is greyed out, its’ greyed out for a reason and if you use the bottom layer slider you will get artifacts. *Edit - You can use it, but pushing a layer’s intensity beyond what the top layer slider can do will cause artifacts IF you change sub division levels. Just keep it between 0 and 1 and you won’t have issues, but it’s really easy to go beyond 0-1 with the bottom layer slider so I would just say don’t use it unless you are staying on the top sub d level.
3. Never change a layer’s intensity while not at the highest sub d level if you are in record mode. As long as you aren’t in record mode you can change a layer’s intensity while on any sub d level. Going by the rules stated in number 2 above. If the layer intensity is greyed out, don’t use the bottom layer slider to adjust the intensity.

I really wish Pixologic would just remove that bottom layer intensity slider, it would solve a lot of the problems people are having.

i finally managed to finish my work with layers, but when i try to bake them they all the model turns black :cry:

im on the highest subdiv and followed your instructions

any ideas?

#5

Why do you need to bake the layers?

Is your model base color black? Try filling it with white.

Do you have polypainting turned on?

Do you have textures loaded?

#6

Thanks for your answrs. i need to bake the textures because i’m going to pose the model and i need to have the 3d details on the model for later 3d printing.

i have the base model on a brownish color and with some polypaint in it ( i started painting without layers) , i have polypaint on now about textures loades, do you mean like spotlight ?

thanks!
