View Full Version : Trying to create a material with a jpg sequence bitmap in diffuse

Hi all!

I'm writing a script and got stuck trying to create a material with an image sequence.

When I create one manually, when I select the JPG it gives me a checkbox to determine if it's going to be a sequence or not, and then the following pop-up asks me start and end frame information. However when it's done the only code it spits out is for assigning the bitmap, but it doesn't setup the sequence. If I run the script, it simply assigns it as a regular bitmap material and doesn't change when you change the frame.



meditMaterials[1].diffuseMap = Bitmaptexture fileName:jpgPath



The first time I create an image sequence manually it creates an IFL file in the same folder. If I load that file with my script instead of the JPG, the sequence works and the material image changes with each frame. But I can't get an IFL until I create a sequence initially. So, I either need a way to create the IFL, or find a work-around to get the sequence to work through the script. Any ideas?

Thanks!

Definitly easier to create the .ifl file.
If you open an .ifl in note pad, you'll see it's just a list of files...

In MaxScript you can get all the files in a directory, open a file to write text and write the array of filenames, one at a time to the file and close...


tnFiles= getfiles <your directory>
FileStrm = createfile <filename.ifl>
for F in tnFiles do
format "%\n" F to:FileStrm
close FileStrm


something like this...

Then assign the filename in the bitmap to the ifl and it "should" work...

good luck

make sure you call sort() on tnFiles, just so the files are in the correct order (presuming they're zero-padded), as sometimes files get collected out of order when using getFiles()

Great, that worked, thanks a lot guys.

Would anyone mind helping me format the path into just the directory?

I'm getting "C:\path\file_0000.jpg" from my input, and when I run getFiles it's only giving me that one, so I assume I have to change this into just the containing directory in order to get the full list of files. Not sure how to do that though..

edit: getFilenamePath, figured it out, thanks!

You can also use wildcards.

GetFiles = "C:\test\*.png"

Cool, good to know! This ended up working out perfectly. Thanks again for the help.
