hi guys,
anyone is using blender?
I am trying to create some fluid.. and i am thinking if there is a way to isolate the fluid? so it will be useful for buyer?
I remember sth like alpha mask? is it same as masking in photoshop?
any guy can give some direction?
thanks.
than why not just do layer and masking in Photoshop to get your effect...
i am thinking if it is possible to generate during 3d render.. like to separate the object from background.
since it is a liquid..i may take sometimes to use pen tool to isolate in photoshop..
Have you tried to change the output under the camera tab to png and choose RGBA button; render, then on the rendered window on the lower right side choose colors and alpha (triangle button), then save as image png
do i need to put the background and object on different layers?
how would the system able to render a transparent background?
thanks.

I just rendered the default cube after setting the output to PNG/RGBA, and saved the resulting render. It opens in Photoshop as a cube with transparent background.
I your render will already be isolated and contain alpha ata as long as you only have th object in the scene. You need to save the render to a file format that supports alpha data...PNG, TGA...
I put a white backdrop at the back of my object.. should i remove it? if i remove it?
I will try to render first..

hi all,
i try to render outpout as png, RGBA..and remove the backdrop.. and i got isolated dark grey background.
is it how blender render as isolated object? i can remove the dark grey background in photoshop..
how can i achieve the transparent background?
thanks.
Here (https://dl.dropbox.com/u/3296211/untitled.blend) is the .blend I used to create this image (https://dl.dropbox.com/u/3296211/untitled.png). On my computer the image opens in Photoshop as a png file showing a cube on a TRANSPARENT background.
When you got to the step after rendering, but before saving, pressing the (triangle button)lower right side choose colors and alpha, did you see the background turn into a black and white square background, i.e. no background? Then you can save as a png that you can use in photoshop, to add a white background for an isolated object, or add into a composition.
Hi, the 'triangle button' is under 'output' tab under the 'scene'?
by the way i am rendering it with cycles..i wonder does it make a difference.
I can render the output with a dark grey background which easy to remove from photoshop, but i wonder how to turn it to transparent in blender.

OK, Cycles. I was using BI. I just tried checking Transparent on the film subpanel of the Render panel, with output set to PNG/RGBA and it rendered with a transparent background using Cycles.
thank you very much!
