Max Stack earns its place for putting its modifiers on Blender's real stack rather than a side panel, and for turning selections into data that flows to every modifier below.
Max Stack - Max Modifiers And Stack is a modifier system for Blender built around 27 Max-style modifiers covering deform, select, UV, array and more. Each tool lands on the normal Blender modifier stack as a Geometry Nodes modifier and appears under its own category in Add Modifiers, so you can reorder it, collapse it, copy it to selected objects, disable it in renders, or apply it like any other stack entry.
Selections work as modifiers too. Build them by angle, volume, proximity, random, helper objects or painting, then combine, grow, shrink, invert, soften, animate and feed the same mask into every modifier below. Change a selection and everything below it updates. Every selection is also a real mesh attribute you can read in the shader editor with the Attribute node to blend materials or drive roughness and emission.
Active modifiers draw their controls directly in the viewport, including deformation gizmos, slice and mirror planes, and UV projection boxes. The Flow Panel gives each selection its own colour column and swatches for routing masks down the stack.
Max Stack - Max Modifiers And Stack is best for blender artists who want Max-style procedural modifiers with viewport gizmos and reusable selection masks that flow down the stack.
Max Stack - Max Modifiers And Stack is completely free to download and use.
Max Stack modifiers appear under their own category when you open Add Modifiers, and each tool lands on the normal Blender modifier stack as a Geometry Nodes modifier. That means you can reorder it, collapse it, copy it to selected objects, disable it in renders, or apply it like any other stack entry. Because the tools sit on the real stack rather than a separate side panel, they behave like the modifiers you already use, and the Flow Panel keeps common stack operations within reach.
Max Stack makes every selection a real mesh attribute, so you can read it in the shader editor with the Attribute node to blend materials or drive roughness, emission and more. Selections are built by angle, volume, proximity, random, helper objects or painting, then combined, grown, shrunk, animated and fed into modifiers below. You can also bake any channel to a vertex group and bring it back when needed, so a painted mask can both shape geometry and control shading while staying procedural.
Max Stack includes a UV Mapping modifier offering Planar, Box, Cylindrical and Spherical projection, each driven by a real viewport gizmo. You move, rotate and scale the projection like a modifier rather than working from a static unwrap, and you can point it at a selection to remap only those faces, region by region. Like the other tools, it lives on the modifier stack, so you can reorder or disable it and feed it the same selection masks that flow down from above.
Max Stack - Max Modifiers And Stack is listed as free in this catalog. Licensing terms can change, so check the developer's page on superhive for the current details before you download. The developer, kleinARt, also provides documentation, and a demo video is available if you want to see more before installing. Everything the plugin offers, from the 27 modifiers to the selection and gizmo systems, falls under whatever license the developer currently lists.
Max Stack provides Copy to Selected and Copy All tools, letting you push one modifier or the full stack onto every selected object. It also includes Apply All and Delete All to collapse or clear the stack quickly when a model is ready to hand off. Because each tool sits on the standard Blender modifier stack, you can also reorder, collapse or disable entries individually, and the Flow Panel keeps these stack shortcuts one click away.
