Copy Render to Clipboard
Simply copies your last render to the clipboard. I've separated it into two macroscripts - one 'CopyRenderToClipboard' copies the RGB data to the clipboard and the other one 'CopyRenderAlphaToClipboard' copies the Alpha data to the clipboard. Note these will both work with 3rd party renderers as long as you are rendering through the 3ds max frame buffer (the image you would see when clicking 'Show Last Rendering')...
Version 2.0 Update
Added a new macroscript to copy the last rendered Alpha channel.
Workflow: take your preview renderings or say you rendered out a quick mask in max that you want to paste into Photoshop on your PSD before sending it off to the client. Saving the VFB output is fine and all but copying to the clipboard is just so much faster.
Credit:
To be fair - this script wouldn't be possible without the AVG extension from Larry Minton and Bobo's clever coding to make the Alpha channel copying happen faster...
Installation:
1: INSTALL APPROPRIATE AVGUARD EXTENSION INTO YOUR PLUGINS FOLDER...
