Substance 3D Painter

I wrote a plugin that mimics the layer composition system of Photoshop. It works fine, but has a issue that shouldn’t be one: In a big scene with 544 layers the script handles all of them one by one, so it creates tons of undo steps flooding my memory. After three and more runs Substance Painter is super slow (and I have a very strong computer!).I can’t believe that neither can I limit the undo steps like in every other application I know for decades within the preferences, I also have no Python API access to it to handle it while the script is running (like disabling undo and re-enabling it later, etc).

Im making assumptions on how some of the projection works but i think most of the projection is dealing with vectors.What id want is a way to reproject by topology where the topology is the same but the proportions might have changedIt would recalculate the difference in the projected stroke vector by checking against the changes between the old mesh and the new one. Since the topology/vertexorder is the same a deformation field can be calculated off of the vertices that are present through something like inverse distance weighting with which you can then recalculate the new projections.I`m sure its not as trivial as i make it sound but if anything like this would exist it would be a really powerful tool.

A few key features in substance 3D painter makes it frustrating to try to hand paint in the program, notably around the color picker. The fact that the color palette needs to be open to use the color picker leads to annoying scenarios, especially since it closes automatically when switching from brush to eraser and back. It would be nice to be able to dock the color picker, or if it just stayed open.Also, it’s really annoying that the color picker always open at the same spot on the screen, especially when using dual monitors. I often use my main monitor to create the base layers and generators, then move the window to my tablet to paint over it, but then the color picker always pops on my main monitor and I have to get my mouse to drag it back to the tablet. This combined with the fact that it closes when switching tool is really disrupting. The only fix I could find was to close the program and reopen which is not ideal.Thirdly it would be nice to hide the brush cursor when picking a

I would like to be able to just hit a key to toggle my brush to material picker quickly, as when painting Normals and AO it is tedious to keep switching between the picker and the brush from the toolbar, especially on these gradient sensitive maps.  This feature would improve workflow incredibly when adjusting these items.  Photoshop, Illustrator etc all do this very quickly, but I was surprised that Substance does not.

The ability when creating the project or reimporting a mesh to specifiy which UV channel to use for texturing/baking. Our techical dept has set up engine shaders that use UV1 for masks created in substance painter using baked data. The current workaround of exporting a seperate bake only mesh with the UV1 moved to UV0 creates a large amount of extra mesh files and can become hard to manage.

In my project, adding layer masks, applying filter effects and adjusting the color levels are very frequent actions. Could we add custom shortcuts only within the layers?If it's customizable, please let me know. Thank you.

Current builds of Substance Painter 3D on Windows do not support handling paths longer than 260 characters (Windows MAX_PATH limit). Starting with Windows 10, version 1607, MAX_PATH limitation can be lifted. However, this is an opt-in behaviour applications must explicitly subscribe to. https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later Could future builds of Substance Painter 3D implement this new Windows feature, thus removing the limit on paths length? Thank you ⭐

Would like to see the ability to adjust the UI scale while in app.  Substance painter UI scale in app.    I don't even use a 4K monitor and the text is so small.  This capability should be in all of Adobe apps.  I stopped using Subtance Painter for over a year because the UI is just too small even after scaling up windows.  I never had a problem with the UI of any Substance apps (Painter, and Designer) before Adobe aquired Substance.  Thank you!

We have multiple in-house tools that utilize the python API and automate portions of the texturing or setup process.  Being able to import splines generated from Maya into Painter to be used for path/ribbon tools would allow for a lot of powerful additions to our toolset. A simple example would be generating a spline from the intersection of metal pieces in Maya and then bringing it into Painter for automatic weld seams with the ribbon tool.

The Python API has always had the ability to load and save files, but no way to read write or use the Recent files.  Unless it is undocumented or somewhere else besides the substance_painter.project module. For now, someone needs to create their own UI or Recent File list if a pipeline tool is created for saving projects. Pythin API Function Request:- Ability to read the list of Recent Files.- Ability to add to or edit the list of Recent Files.- Saving or Loading either adds to the Recent Files,  or that the open/save/save_as functions offer a save to recents flag/option.This would make wrangling projects so much easier.Thanks again for the fantastic integration

When iterating textures, it becomes time-consuming to repeatedly export each texture set into its own directory. Currently, exports are limited to a single output directory per export, which means I need to re-export each texture set separately into its respective folder. This becomes a time sink for any project with multiple texture sets.It would significantly improve workflow efficiency if we could create multiple “General Export Parameters” templates, each with: its own output directory an assigned texture set After setting these up once, re-exporting could be done with a single click while automatically routing each texture set to its correct folder.This would streamline iteration-heavy pipelines where textures are frequently re-exported.If there are technical or compatibility reasons this hasn’t been implemented, I’d also appreciate insight or recommended alternatives.Thanks!

Hi, hope you’re good 👍🏾I’d like to request an option to point at a specific After Effects installation for the Export > Send to After Effects command.Use case is that I have a bunch of different versions installed for older project/plugin compatibility reasons, plus I’m working in the AE Beta for testing most of the time. The current functionality seems to automatically send to the most recent release version, and it would be a big timesaver to be able to specify which version of AE to send to, especially as this command can generate just and GLB file without all the maps as well.I’d imagine the most straightforward place to put this would be in the config options for Send to AE - there could be a dropdown with all the recognised installations, and a checkbox to enable selecting a version manually.With all the good work that the AE team are doing with substance and 3D integration right now, having this flexibility would offer quite a big quality of life upgrade.Cheers!

The UDIM numbers are not useful for game engines, yet they are essential for painting and baking across multiple parts of the mesh in Substance Painter.   Instead of having to look up what part 1004 is, it would be nice if I could export it with the name I put on the tile within Substance Painter.

allow multi axis mirroring. I think it would be better in fact to just remove mirroring at all and have it as an effect, which gives better control and avoid having to repaint if your forgot to put the mirror on, or remove the mirrored side if you decide it is better but have to use some workaround as the mirror is destructivefor example texturing a sword, I may need to reflect details to the other side and back for the blade, which is impossible and I need to use a lengthy workaround such as using shared uv space and then baking or something else, which is not really ideal... would much appreciate an update like this..

When painting textures, there are situations where I need to add a new channel (for example, Opacity) at a later stage. Currently, when a new channel is added, it is automatically enabled for all previously used materials, even if I do not want those materials to use this channel. I would like to have control over how new channels are applied to existing materials. Specifically:An option to automatically enable the new channel for all existing materials, or Have the new channel disabled by default for existing materials and allow the user to manually enable it per material. This could be implemented as:A confirmation dialog when adding a new channel, or A project-level preference that defines the default behavior. This would prevent unintended changes to already finished textures and improve workflow flexibility.

Currently the way strokes are stored in 3D space makes Substance 3D Painter a really cool tool for non-destructive workflows. I love how you could literally change the topology and UVs and keep your texturing work.Unfortunately this becomes a bit of a problem (specially with character work) where I keep doing modelling updates (no topo or UV changes, just shape) and reimporting the mesh would make my texturing work break, as parts of the model move around a bit but the strokes stay in their original place in 3D space.It would be really really amazing if one could choose to update stroke position based on topology instead of 3D space. Even if its not perfect, most texturing work is through masks anyways. Existing stroke points would have to bind to the model (similar to a Maya wrap or a Blender surface deform) and move to their new position. If using face normals this could even allow rotation. This would unlock full non-destructive workflows in Substance 3D Painter.At the moment, my on

Hello Adobe Team,I’m writing this message out of real frustration, but also because I genuinely believe there is a huge missing tool in today’s 3D workflow.I am a 3D artist, and I create my own HDRIs because I care about lighting consistency, artistic direction, and originality. But honestly?Creating a custom HDRI today is a nightmare.To create a single HDRI from scratch, I am forced to jump between:- AI image generators to get a base idea- Photoshop to clean, fix projections, and manually adjust equirectangular distortions- After Effects to add atmosphere, glow, sky effects- HDRI Light Studio just to properly shape the light- Blender to constantly test if the HDRI actually worksThis is not creativity.This is technical survival.Because of this mess, most artists simply download HDRIs from the internet. Not because they want to, but because the industry gives them no real tool to create their own easily. This kills artistic control and breaks creative flow.And the worst part?The problem

Hello,I would like to suggest adding the functionality to name textures on export based on their Udim descriptive tag, rather than just the texture set or numerical Udim identifier.This way I could export textures with a similar descriptive naming as if using distinct texture sets.This type of naming is required by the project that I am on and I don't want to have rename all my textures post export.Also, using seperate texture sets is not an option, as I need to paint across UV tiles.Thanks

I needed to export a single "material preview" texture today and realized it can't be done. I never considered that this wouldn't be possible, though I know it's not normal anymore for a game to use one texture. I ended up screenshooting the material preview and managed to get what I needed, but I would perhaps like the ability to do that again as the need arrives.  However, the screenshot work around is fine.If there is a way to do it and I have overlooked it, please let me know.  

Is there a way to add an alpha color or an eraser to polygon fill, so we can erase using polygon fill? That will come in handy when we are filling without using in mask. Sometimes less mask has better performance, so for some small things I wouldn't bother to use it.

When drawing in 2D view the background color is too dark, is there anyway to change the background color.

Emissive in Iray caps out and is not nearly strong enough for certain renders.You can normally only get the strength to "1" using the sliders in Iray mode.It is possible to get the emissive to "100" if you set it in painter mode and then swap to Iray mode.(this is a bug, but it works in my favor)However, even the "100" is a hard cap that sometimes isn't enough.I'm currently trying to render a car, where the headlights needs to be much brighter than what the emissive setting allows me to set.Since real headlights have pretty small but very strong lightbulbs, they use reflectors to boost that light even more to get sufficient brightness.  Even with a reflector being 100% metallic, with 0 roughness, the bounce light is not strong enough whit the emissive getting capped at "100" in painters Iray mode. I also use emissive materials to create bounce lighting in some cases. I can add a surface and add an emissive material to it to simulate light sources in my scene. If I get more co

Hello, it would be great if my two suggested improvements to Substance Painter could be added. They would be very useful for my texture creations. These are two tools that exist in Adobe Photoshop: the lasso (all versions) and quick selection (all versions depending on what you want to do) . Thank you in advance if this is done ^^
