Vraybitmap back to bitmap

V-Ray V-Ray for 3ds Max General

Hi,

I am converting Vray to Standard materials because my client wants to use the Autodesk viewer. I am using VrayBitmaps so I need to convert them back to the standard bitmaps if possible.
I know there is a standard bitmap to VrayBitmap script, but I would like have it the other way around. Does anyone have some script intelligence to make this work?

Anyone from Chaos?

We do not provide such a script, I’m afraid. Writing one quickly will be challenging since the freshly created Bitmaps should be replugged accordingly.

Ok, I understand Aleksandar! Can you give me a solution for exporting *.max files with bitmaps which can be opened in an Autodesk viewer? Converting to an Obj or Fbx does not work because of the VrayBitmap which are in al my maps. I have made 120 models which are now using VrayBitmaps. :frowning:

This should work to at least copy the filename over to a standard bitmap. It doesn’t do anything with coordinates, crops, uvs, etc though so it’s a bit limited. Might be good enough to get something over to the viewer though. Really untested though so save beforehand.


for b in getClassInstances VrayHDRI do
(
    if (b.HDRIMapName != undefined) and (b.HDRIMapName != "") do
    (
        new_bmp = BitmapTexture()
        new_bmp.filename = b.HDRIMapName
        new_bmp.name = b.name
        replaceInstances b new_bmp
    )
)

```​

Thks dlparisi, I will try it out first thing in the morning!

I’ve learned something, too. Thank you for answering!

EDIT: Created a proper script with UI for anyone wishing to use Autodesk Viewer. Note that it replaces only valid (not empty) VRayBitmaps used in the scene.
