++ Works with All Assets ++

New added support for 3ds max 2023
New added support for VRay 5.2 - new Color space in VRayBitmap
New method to speed up reading image size and color depth - especially for large EXR, HDR, TIFF, TX etc

Bitmap Tracking / Resizing... is tool similar to Asset Tracking. But it gives more possibility to work with bitmaps:

- Support for All Assets
- Sort files by name, image width, height, file size, path, gamma, texture name, status (Found - network, Found -  local, Not found)
- Resize to JPG selected bitmaps to specified size or to Nearest Power of 2
    - can be used to resize and repath selected bitmaps (by size) before sending to external renderfarm,
    - resize bitmaps in large animation sceens to reduce memory ussage,
- Convert... see below
- Change / Rename paths (with paths history and rename path prefix eg. change only server/drive letter)
      * Choose path from history or scene paths
      * Pick new path
      * Rename paths beginng ( drive letter or paths C:\sample\abc\ and rename them to Z:\3d\sample\abc\ )
      * Find and Replace part of paths - supports Regular Extension
- Multi-threaded Auto-Relink with progress dialog
- And More...

- Select objects by selected bitmaps
- Select / show materials by selected bitmaps
- Select duplicated filenames (coming in next version)
- Copy local files to network with auto path replacing (for distributed / network render)
- Copy Selected / All to one path with path replacing or just copy files - collect selected to project forlder or quickly copy+change selected paths to not show your paths structure
- Shows local and network files -> Status -> OK - network,  Found -  local,  Not found ( eg.: easy sort and select all local -> copy selected to network)
- Supports .ifl - sequence image files - resize / convert / copy / path replace
- Supports Mari Tiles and the <UDIM> Tag
- Supports Mudbox Tiles and the <UVTILE> Tag
- Script works with Bitmap Texture, VrayBmpFilter and VrayHDRI, CoronaBitmap, FStormBitmap and all other assets
- Change gamma in selected - works only with jpeg, bmp, gif, tga, tiff in Max 2014 and up. (not in demo)
- Check / Change gamma in VRayHDRI
- Converts to Tiled EXR - it sends comments to img2vrayexr and translate BitmapTexture to VRayHDRI. (not in demo)
- Converts to Tiled TX - it sends comments to maketx and translate BitmapTexture to VRayHDRI. (not in demo)
- Rename Files on HDD - 5 methods:
   - Copy with new name on HDD only
   - Copy with new name on HDD and rename in project paths
   - Rename on HDD only
   - Rename on HDD and in project paths
   - Rename in project paths only
- Convert to JPG
- with settigns dialog (Quailty, Smooth, Linear EXR/HDRI to sRGB JPG)
- Save Cropped as JPG - with settigns dialog (Quailty, Smooth, Linear EXR/HDRI to sRGB JPG)

- External Bitmaps options:
    - possible options: Resize / Convert to Tx / Exr / Jpg (Tx files can be only converted in ths version)
    - how to do:
      1. click top middle button and choose External Bitmaps
      2. drag and drop folder or image files supported by Max (including Tx files)

SubTree bowser to Show Materials by selected bitmap assets - and drag and drop to Material Editor:

Excellent script

Excellent script helped me a lot, wonderful before I suffered a lot with 3d studio max map paths, after that my productivity increased a lot.

Best Script Ever

Highly recommended !

Highly recommended !

Super useful and well done script. One of the few really good one.
Well spent money and Pixamoon support is on the same level - just great.
Rest scripts are also amazing!
Don't waist more time and just buy it - it is the best.
