MechaPaint 2.1.0 Patch Notes

v2.1.0 / November 2026

ACES EXR export, ready for Blender 5

ACES

• Export textures as EXR. The Format row in the Export window now reads PNG, TGA or EXR. Settings, Texture Export has the same choice for your default.
• Pick your color space. EXR files come out in ACEScg, ACES 2065-1 or Linear sRGB. ACEScg is the default, the working space Blender 5 uses for ACES.
• Color maps are converted, data maps stay raw. Base Color and Emission are converted into the space you pick. Normal, Rough, Metal, AO, Height and the other data maps keep their exact values, so your surface reads the same in every app.
• The file says what it is. Each color EXR carries its color space in the file header, so apps that read it can set the right space for you.
• Light, clean files. Half float and ZIP compressed, with alpha wherever your texture has it.
• FBX too. Export an FBX with EXR picked and the EXR textures are written right beside it.

Blender 5 ships with ACES built in, and a lot of artists are moving their scenes over to it. As far as I know, MechaPaint is one of the first painting apps to hand you ACEScg textures straight from the Export window. What matters is that your paint drops into an ACES scene with exactly the colors you chose, with zero conversion steps in between.
