This is script to change bitmap load gamma in whole scene or selected Bitmaps.
It can change gamma in all / selected bitmaps (now filtered by selected objects).

It helps to switch gamma in Normal Bump to prevent VRay render crash
( when merged models came with automatic gamma in Normal Map)

Normal Bump for VRay Render should be Override 1.0
VRay Normal Map -
recomended - Override 1.0
Corona Normal Bump - recomended - Automatic

Apply by
Object selection - All, Selected only
Bitmap type - AllNormal Bump, VRay Normal Bump or Corona Normal Bump only
Change All / Selected Custom input gamma works in max 2014 and up.

It is recomended to change gamma only for Basic Bitmap Image types:  ".bmp",".gif",".ifl",".jpg",".jpe",".jpeg",".png",".tga",".vda",".icb",".vst",".tif",".tiff"
New version has option to change gamma in other file types but without custom settings (exposure, layers etc in .psd .exr)

normal map gamma

Thanks for this suggestion :)

I'll do second list for Map types.

Also, Bitmap Tracking / Resizing... will have that too + you will be able to see actual input gamma for every bitmap ans see where is is loaded.

Thanks again!

Any more suggestions ?

nice script, but I have a

nice script, but I have a question. I only have to change the input gamma of the bitmap in a normalbumpmap when working in gamma 2.2. is this possible, I only see a bumpmap option...?
and maybe it would be great if you could implement the gamma change option also for colors too.

best regards

Thanks for comment,

I'm sorry, but for now only there is download counter. It helps me to know which scripts I should work more on.
And still it's free registration and free download.

I'll do later counter on my web. But have to find time for it.
