Hello
I’m trying to save image with transparent background. I know that there is a checkpoint Preferences->Rendering->Background->Use Environment Alpha.
If im saving image manually with turned on “Use Environment Alpha” – the image has transparent background. But if im saving image with script the image has black background =(
Here is my code example:
f = "D:\\1.max"
mergemaxfile f #select;
renderFilename = getFilenameFile f + ".png";
pngio.setAlpha true;
pngio.setType #true48;
rendOutputFilename = "D:\\"+renderFilename;
rendsavefile = true;
bm = render();
bm.FileName = "D:\\"+renderFilename;
save bm;
delete selection;
I’m using Vray 2.40 for render
After render finished there is an image in V-Ray frame buffer and saved file D:\1.png with black background. Then i’m saving image manually from V-Ray frame buffer and background is transparent as i told up there.
I dont understand what im doing wrong How to save image with transparent background with maxscript?
no error for me:
delete objects
plane width:200 length:200
teapot()
pngio.setAlpha true;
pngio.setType #true24; -- also works for #true48
bm = render();
bm.FileName = "D:\ est.png";
save bm;
In windows explorer, the preview still shows black background but if you open it in photoshop alpha is here.
the problem was in Vray Frame Buffer…
I’ve turned off “Enable built-in Frame Buffer” (render setup->V-Ray->V-RayLL Frame buffer) and now its all OK! SUDDENLY o_O
