What for

After changing UVs in Blender, I need to manually re-send UVs back to Aseprite using the menu option. It would be nice if this was automated, or on a timer I could configure (similar to the auto-reimport addon). I frequently tweak UVs as I'm drawing and it would save some keystrokes/clicking each time.

How

Either by detecting changes in the UV map (if this is possible in the Blender UI), or by setting up a configurable timer so it can just be resent every couple of seconds.

Relevance Please classify it by leaving, removing, or adding list items

• It affects everyone using the tool
• It's a very repetitive task

Reality Sending a UV map to Aseprite yields a mix of the UV map and some graphics card framebuffer garbage, sometimes only garbage.

Expectation To get a transparent layer with only the UV map outlines.

Logs Shows nothing after Info: Aseprite connected

Version info

• Blender 3.0.1
• Aseprite 1.3 Beta 10
• Pribambase 2.2.0
• OS: Linux 5.14.21 (KDE on AMD using X11)

Additional context

It did work in the first released version, if I recall correctly. I guess it can just as well be Blender or some recent graphics driver bug.

Reality Addon loaded in blender (latest release) and aseprite (v1.3 beta16 64bit)

Sync blender and aseprite successfully (both show connected)

when creating a new sprite via the sprite menu in blender, aseprite console says "appdata/roaming/aseprite/extensions/pribambase/snyc.lua:267 websocket failed to send data

Evidence

Reality Image changes in blender are ignored until something else flushes them, e.g saving and reloading the image.

Expectation textures change every time image data cahnges

Logs In blender, please click Window > Toggle System Console and see if there's anything suspicious there. On Windows, copying from there is done by selecting text and right click.

To paste it here, use triple ticks like this

Version info blender 3.1

Additional context blender's new partial image update system is buggy, e.g. like this.

E.g. this test works in older versions, but not 3.1. Should fill image with random shade of gray on each call, but in 3.1 only works forst time; than need e.g. to save and reload the image.

import bpy
import numpy as np
from random import random

try:
    img = bpy.data.images["Untitled"]
except KeyError:
    img = bpy.data.images.new("Untitled", 32, 32, alpha=True)


gen = np.ones((img.size[1], img.size[0], img.channels), dtype=np.float32) * random()
gen[:,:,3] = 1.0
img.pixels.foreach_set(np.ravel(gen))


img.update()
img.update_tag()
for area in bpy.context.screen.areas:
    area.tag_redraw()

Reality The addon crashes when trying to enable it.

Expectation It should not

Version info

• blender 2.83
• Aseprite any
• Pribambase 2.1.1
• OS win64 (any?)

Additional context ouch

• [x] sent a patch to ase that allows scripts to subscribe to filename change event (it already exists internally)
• [x] patch got merged, now waiting for the next release that will include it
• [x] use that functionality in the plugin

Currently, name changes are handled with the next change in undo history

Prescale can be used temporarily to make pixel snapping snap to half-pixels

Prescaling is already implemented and used for reference images

• [ ] choose when creating or opening a sprite
• [ ] change for an existing texture (an operator?)
• [ ] apply when receiving data from ase
• [ ] undo before sending data to ase

Reality When layer sync enabled, all layers with the same name are synced to the same image in blender.

Expectation Layers in blender have separate images, same as they do in aseprite.

Logs not relevant

Version info not relevant

Additional context Aseprite default names are like that when there's several layer groups. Use same .001 convention when creating 2nd+ image as blender uses everywhere.

Sometimes, syncing UVs multiple times. possibly along with undoing/redoing, makes the UVMap layer disappear in the layer list while the image remains on the canvas (can be moved and resized even).

Even more strange, it seems that it got fixed with Reload All References for someone, which is completely unrelated operation but it could e.g refresh the list of textures in aseprite. Could have to do with lua hogging a reference to image?

Perhaps a good way to deal with that would be contributing reference resizing to ase api, as right now it takes a specific sequence of illogical actions to achieve the required behavior of those.

Shouldn't be surprizing for those familiar with blender, but as an option, it can be adjusted on sync, like e.g. action strips are. There's mesh and UV map to consider.

Includes maya, blockbench, blender forks, krita, and whatnot.

While a small portion of code can be ported, most functionality has to be reimplemented to account for the software structure. So the workload during development and testing grows by the factor of (raster editors to support)*(3d editors to support)

The approach that I use/suggest for pixel-friendly unwrapping is a sizeble amount of information to digest. Part of that comes from needing to use a small bit of general purpose tool, which were created with a different goal in mind, then fixing the result. So it’s more akin to solving a weird puzzle.

At the same time, this kind of unwrapping is very repetitive, and mostly consists of simple manipulations. Separating them into dedicated tools with a visual feedback will create a good flow that feels natural to beginners, and speeds up the process to everyone.

It's a pretty sizeable amount of work starting at analyzing the workflow, but the potential benefits are huge
