texture_displacement_patch_frame picks the world axis least aligned with
the patch's average normal. With no patch there is no normal either, and
the axis came out of the +Z fallback for it - so it was +X, while its
test asked for the upright frame the fallback is meant to give. An empty
patch now answers +Z outright.
Nothing removed the even mesh over a texture's flat parts unless the
budget was lowered until simplification had to run. Collapses stay under
a thirty-second of the resolution: on the test map 387584 -> 369876
triangles, with the print unchanged (0.02% of the extrusion).
An earlier attempt was reverted for a 21% heavier result. That was the
colour despeckle switching itself off, not the collapsing: it keyed off
the face parent map, which any collapse empties.
Relief preserved from an earlier bake is counted on top of the budget
instead of eating into it: baking a second area went from ~214 k
triangles to the ~1000 k it was given.
When the resolution needs more triangles than the budget allows, it is
said before the bake under Resolution and again afterwards.
- Bake: each layer is sampled only on its own painted area; analytic
projections used to stack every layer over every painted region, so the
top layer's texture showed on all of them (colour sampler too)
- Auto resolution follows the texture's texel size and sharpness again
- Unwrap: charts cut by each face's own normal (a cube gives 6 islands, not
12 triangles); non-disk charts (tubes, closed shells) are split until they
flatten; connected nets test real triangle overlap, grow from the largest
chart and are packed side by side
- UV edits are stored per unwrapped copy, so dragging a seam vertex no
longer moves its copies in neighbouring islands
- UV pane: tool strip with unwrap settings moved in from the panel, sharp
HiDPI icons, clearer island/edge/selection drawing with hover, texture
picker from the thumbnail, texture no longer lost on reopen (GL state
from the 3D view, background upload retries)
- Panel: whole-model select/erase as icons in the tools row; inactive
layers' paint shown muted; colour textures shown in colour in the picker
- Built-in displacement texture library
- Tests for unwrap segmentation, connected nets, UV edits and per-layer
sampling
Colour height maps now displace the same way up as grayscale ones. A
truncated or corrupt PNG in the texture folder or a project file now
loads as an empty texture instead of aborting the app, and a 16-bit
colour PNG is converted on load rather than displacing as noise.
