If downloading on ARM, make sure to update your GPU driver to the latest version. Qualcomm’s latest drivers can be found on their website.

This release includes Redshift 2026.7.0 - older versions (2026.0.0 and higher) are compatible but will not include new Redshift feature and enhancements to Redshift integration and performance.

Bug Fixes

Mograph

• Fixed an issue where clones driven by a UV texture did not correctly match the grayscale values of the controlling texture.

UV Tools

• Fixed an issue where hidden UV polygons were unintentionally affected by “Reset & Unwrap” and related UV operations, causing repeated scaling that could shrink UV islands until they became too small to pack correctly.
• Fixed a crash that could occur when interacting with Paint Textures.
• Fixed an issue that could cause exponential memory growth and crashes during animation playback when deformed objects changed topology.
• Fixed a crash that could occur when editing objects in the new UV Editor, caused by invalid data being created during object resizing.
• Fixed a crash that could occur when deleting an object while the Seam tool was active in the UV Editor.
• Fixed an issue where viewport and live render previews would not update correctly while editing UVs when subdivision surfaces or certain deformers were active.
• Fixed a crash related to UV updates on sculpted objects, caused by missing handling for changes in the updated UV system. The fix also improves stability when rebuilding subdivision surface topology.
• Fixed an issue in the UV Editor where Weld operations could incorrectly trigger Undo actions, causing UV islands to revert to previous positions instead of merging properly.
• Fixed an issue where the Seam Selection tool could create unintended seams in unrelated parts of a mesh, including incorrect results when using loop selection mode.
• Fixed an issue where “Mark as Seam” did not correctly apply to symmetrically selected edges when the selection was made in the UV Editor, leading to inconsistent behavior compared to selections made in the viewport.
• Fixed an issue where the Seam Selection tool could not remove the last remaining seam loop in the UV Editor, resulting in inconsistent behavior compared to the 3D viewport.
• Fixed an issue where deleted seam data could persist and reappear when creating new seams in the UV Editor.
• Fixed an issue where undoing seam selections in the UV Editor could revert multiple seam changes at once instead of undoing them step by step.
• Fixed an issue where the Seam tool could fail to select loops in the UV Editor immediately after loading a scene until the object was reselected in the Object Manager.

Viewport

• Fixed an issue where multi-instances in the viewport could flicker or display incorrect materials when using identical objects with different materials. The problem affected viewport rendering only and could occur with cloners, scatter setups, and other multi-instance workflows.

Volumes

• Fixed a crash that could occur on application shutdown when using volume objects inside cloners with multi-instances.
