Cage experimental issueOpen for Voting

Problem with baking rounded objects (but this apply to many other cases).Example with this Cactus Sculpt. Here is one layer of the upper flower _high, viewed from side and from above: Automatic cage (experimental), works amazingly well for tons of complex objects, but not for some simple ones like the example above. If I bake with Cage type set to: Automatic (experimental), it feels like the Max rear distance is infinite and catches anything behind faces. If I bake the more traditional way with a hand-made cage mesh, or with the basic Distance-based Cage type, it works perfectly fine: So basically, there’s an issue with Automatic (experimental) Cage type. The automatically calculated “Max rear distance” cannot be controlled by the user, and the one that’s calculated automatically seems to go indefinitely, baking everything on the opposite side of my polygons normals direction.Of course there are tons of workarounds. But it just doesn’t feel right. Esepcially given how much of a revolut

Baking errors on new PCOpen for Voting

Tested this on a dummy file and i'm getting the same issues, images attached below. So I just built a new PC and started working in substance again only to realize some of my bakes are completely broken. AO in particular has these weird artifacts appearing all over the model. The model and UVs are fine and my GPU drivers are updated to latest. At my wits end trying to fix this. PC spec is 7600x3d and 7900xtx with 32 gigs of ram. Windows 11. I'm using Substance Painter 2022 Steam Edition.

In a few minutes all VRAM is usedOpen for Voting

Since 12.1 (this is 12.1.1) the VRAM usage of Substance Painter is crazy. There's another bug report about performance issues but for me it wasn't clear if it's VRAM related.What happens:While working on a very small scene which only uses like 3GB of VRAM it skyrockets to the max in the matter of minutes while working on it.This is 100% a memory leak and happens as well with version 12.1.1My system is nothing special, Win 11, 64GB, i9-9900K but what makes it a bit more special is the fact I have 2 GPUs, a 3090 and 4090 both with 24GB VRAM.I tried to force using the 3090 using the options inside Windows Display > Graphics options but that doesn't help, it only switches the issue to the 3090. I'm currently at the Nvidia 610.62 Studio Drivers.If I quit Substance Painter while it hugs the 24GB it will roughly empty 12GB and after like a minute it gives me back another 10GB of VRAM.It also doesn't really matter what I do, the screenshot attached is a storyboard where I only hide/unhide m

Polygon Fill Eraser or Alpha ColorUnder Review

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.

Additional texture export optionsOpen for Voting

1. Add options for different resolutions for specific textures.2. Allow for custom sufix/prefix withouth having to create new output template. Our game engine uses additional maps to run sheen/sss ect. We have set up the custom user channels to paint these maps.However, to save memory, we dont need these maps exported out at the same resolution as the base maps.It would be nice to be able to specify a different export resolution per texture the same way you can specify a file type and bit depth.  Also having options of 1/2, 1/4 or Double the texture set size as well as specific resolutions might help too.Being able to add a prefix or sufix without having to make a new output template or changing the material name or manually changing the file name would be helpful when making variations.  If we exported our textures but also wanted a clean version without the dirt for example we could just add a simple _clean prefix without having to search through an extensive list of o

Can we have an option to use imported resources as a link?Open for Voting

Currently, all imported resources are embedded in the project files.In many cases, artists may use the same images/textures across multiple project files. As a result, these resources are unnecessarily stored in each project file, taking up a lot of space and making the project files larger. Using linked resources would prevent this duplication.At the very least, having an option that allows users to choose how they want to store their resources would be very welcome.Each option has its own use case. This is why this should available for users.

Material normals are blank in the Dynamic Layered Material workflowOpen for Voting

1.Open new project2. switch shader to pbr-material-layering or pbr-material-layering-10-mats3. assign all materials to any material that has distinct normal map(e.g. Stylized Wood Bark)4.

Why isn't SSS rendering properly for me?

Sub Surface Scattering isn’t rendering properly for me. I have tried almost everything from changing the shader to remaking the entire model Weirdly brightens up the model when I turn on SSSRenders fine without SSS. As you can see, it weirdly brightens up the model. It’s renders fine without SSS. I just can’t figure out how to render out the SSS. I have baked a thickness map and inverted that map for the SSS and it should render out without any problems. Any Help will Really be appreciated.

Editable 2D Warp Grid for logos and decals, with native 2D viewport API supportOpen for Voting

I would like to propose an editable 2D grid warp workflow for Substance 3D Painter, and request a supported public API for integrating tools like this into Painter’s native 2D viewport.I have developed a working plugin called 2D Warp Grid. It lets artists reshape projected logos, decals and other layer content in UV space without changing the mesh UVs. A typical use case is correcting the shape of a logo on a curved surface after it has already been placed.Video demonstration:Watch the 2D Warp Grid demonstration on Google Drive (no sign-in required).Current plugin capabilitiesGlobal: a grid over the full 0–1 UV area. Local: a rectangular grid fitted around the layer content. Custom: draw a rectangular area directly in the 2D editor. Independent row and column resolution, up to 10 × 10 control points, with Smooth and Linear interpolation. Move individual points, or select multiple points with Shift and move them together. Move, rotate and uniformly scale the whole grid in Local and Cust

Feature Request: Per-stroke Normal blending mode (Replace/Overwrite) in Substance 3D PainterOpen for Voting

When painting multiple strokes on the same layer, the Normal channel blends strokes in an additive/accumulative way by default. There is no brush/stroke-level option to make a new stroke replace or overwrite the previous stroke’s normal information. To achieve an overwrite result, I have to either change the layer blending mode or create a new layer for every stroke. Creating many layers hurts performance and makes the project messy; changing the layer blending mode affects the whole layer and does not solve per-stroke behavior.

Painter 12.1.x (Vulkan) — viewport stops rendering permanently, only with pen input during camera navigationOpen for Voting

Environment: Substance 3D Painter 12.1.3, Windows 11 22631, RTX 5080 (NVIDIA 610.62 / 610.74 / 616.56 — identical on all three), Wacom Cintiq 22 as primary display, Windows Ink enabled per Adobe's pen guide. Reproduces since 12.1.0.Symptom: during a normal painting session the viewport stops updating permanently. Menus, panels and the layer stack keep working; Windows never flags the app as unresponsive. F, view toggles, resize, dock re-attach, minimize/restore do not recover it. Only a restart does.Conditions (several dozen occurrences over two months):- Only while using the pen. Never with the mouse — zero occurrences in mouse-only sessions.- Almost always during camera navigation (Alt+drag), not during strokes.- Often preceded by a sudden camera jump. Worse after Alt+Tab and back.Evidence collected on one instrumented occurrence (2026-09-07 20:10):- Minidumps (6 total): the "SAL Render Thread" is parked in std::condition_variable wait (ntdll!NtWaitForAlertByThreadId → RtlSleepCondit
