vray AND targa file problem

[ant_sutton]

Hi guys.

 

I am rendering an interior with a bright white outside from the windows. I'm sure I used save the file as a tga file and open it in photoshop and the white background would not be there, so I could just add a photo background. When I open the tga file this time, the white background is still there. What am I doing wrong. Is there another way to add a background image post render?

 

thanks alot

i don't use vray, but make sure you are saving with 32 bit and premultiplied alpha to make sure you have an alpha channel. i believe one or both of these settings should fix your problem.

if you go to the channels tab there should be an extra channel - use it as a selection (ctrl click the channel layer) and then delete or mask off. Needs to be saved as Calvin suggests

or got to 'load selection' in 'select' menu in p/s and load alpha selection.

hi guys.

 

since you are all talking about tga.im having a problem where i set the image format to tga in vray but when it renders, it makes it a jpeg file.

 

im using maya 2009.it renders fine on an other computer but on mine it renders jpegs.the file has a reference in it.could information from the ref file over rights the main file?i checked the ref file and its also set as tga

 

and is there any good documentation on vray for maya.i know.its a beta.

 

thanks.
