When we had finished making a render of ours 3dmodels in 3dmax the nex step is insert the resulting render in Photoshop for Post-producing. With this tutorial we are going to explain how to save your renders including the alpha channel, and how to delete the unwanted background in Photoshop.
3D Studio Max – Saving your renders
First of all you have to make something in 3ds max and render it.
When you have rendered, save your image and choose the *tga format and click "save". (See image)
Then you will get another pop-up window. Make sure you set the "bits per pixel" at 32bits and select "compress" and "pre-multiplied alfa" (See image), then click "save". The reason for saving the render in *tga format, is to embed the alpha channel within the image file.
Tip – The Image quality.
-Always render your images in high quality. More pixels = higher quality.
-It's always better to scale it down than up.
Photoshop – Deleting the background.
Start up photoshop and open the *tga image you previously saved from 3dmax.
To delete the background colour of your image, go to "channels" and while holding in the "Ctrl" button, click the channel called "Alpha1". The alpha channel should now be selected.
Now invert the selection by going to "select – inverse" and hit the "delete" button on your keyboard.
So with this simple steps you can export your 3dsmax renders to photoshop and eliminate its background to use the one you desire.
