fr Defaults fix
by Jon Seagull
fr Defaults fix is a startup script for 3ds Max that changes how finalRender treats new objects. It ensures objects are created with send/receive GI and receive caustics turned on rather than GI disabled.

MatSnap AI earns its place for combining image and text-based material generation with automatic PBR map extraction, a seamless tiling editor, and one-click Corona Physical Material setup inside 3ds Max.
MatSnap AI is an AI-powered script for 3ds Max that generates seamless, high-resolution PBR materials from screenshots, photos, and text prompts. It bridges AI texture generation and 3ds Max, so materials can be created without leaving the workflow or searching through texture libraries.
There are two input paths. You can paste an image from the clipboard, point and click on the specific material you want, and generate a clean high-resolution Diffuse texture. Or you can describe a material in text, such as "worn concrete wall" or "clean oak wood floor," with the AI respecting strict 2D perspectives to produce accurate flat textures. From the diffuse, it extracts Normal, Bump, Roughness, Displacement, and Ambient Occlusion maps. A built-in seamless editor adjusts X/Y center-offsets and gradient blend softness with live real-time grid previews for tiling.
A single click creates and correctly wires a complete Corona Physical Material, with proper gamma settings, into the Slate Material Editor. Real-time controls adjust bump intensity, displacement height, and roughness, syncing instantly to the active material. It runs on 3ds Max 2023 to 2026 and requires a personal Google Gemini API Key.
MatSnap AI is best for 3ds Max artists using Corona Renderer who want to generate PBR materials from reference images or text prompts inside their workflow.
MatSnap AI is completely free to download and use.
MatSnap AI is compatible with 3ds Max 2023 through 2026, so 3ds Max 2026 is supported. Across those versions it handles the full flow: generating a Diffuse texture from a pasted image or text prompt, extracting Normal, Bump, Roughness, Displacement, and Ambient Occlusion maps, tuning tiling in the seamless editor with live grid previews, and wiring a Corona Physical Material into the Slate Material Editor. Generation relies on a personal Google Gemini API Key that you supply yourself.
MatSnap AI currently supports Corona Renderer for automatic material setup. With a single click it creates and correctly wires a complete Corona Physical Material, including proper gamma settings, into your Slate Material Editor. Real-time controls in the script's UI then let you adjust bump intensity, displacement height, and roughness values, with changes syncing instantly to the active 3ds Max material. The derived PBR maps it generates cover Normal, Bump, Roughness, Displacement, and Ambient Occlusion.
MatSnap AI requires a personal Google Gemini API Key for generation, following a bring-your-own-key approach. You supply the key yourself, and the AI then powers both input paths: turning a pasted image into a clean Diffuse texture when you point and click on a material, and turning text descriptions such as "worn concrete wall" into flat textures that respect strict 2D perspectives. The generated diffuse feeds the automatic extraction of the additional PBR channels.
MatSnap AI is listed as free in this catalog. For current licensing details and any terms around the required Google Gemini API Key, check the developer's page. Functionally, the script covers image-to-PBR extraction, text-prompt generation, automatic PBR map creation, an interactive seamless editor with live grid previews, and one-click Corona Physical Material setup inside 3ds Max 2023 to 2026. A demo video is also available.
