Is there an easier way to cut out renders other than using the eraser tool in Photoshop?

Cuz that's a pain in the ass >.<

You Could Use The Laso Tool ?

magic wand tool, magic eraser, magnetic lassoo, polygonal lassoo, pen tool, magnetic pen tool...

Yeh Thats The One I was Thinking Of But yeh Chris know i think ll

What about the extract tool and history brush?

Pen tool or Extract tool usually work pretty well. I'd say learn to use the pen tool since it is ultimately one of the most powerful tools in Photoshop.

Well, there's the easy way and the hard way [methods that I generally use]. These are:

The Easy Way: Since Cinema 4D is a 3D app, I'm assuming it can render/save an image in PNG format. This means you just render the object/model you want to use in Photoshop and then save it as a PNG file. If there are options to 'preserve transperancy' [called an 'alpha' channel in tech talk] in your C4D 'Save as' box, enable it. If C4D supports it [which I think it does], your model should be rendered and saved with a transparent background.

The Hard Way: If you want to isolate an element in an image [or you have rendered your C4D model as a JPG and now want to isolate it in Photoshop], go take a look at the Channels tab [usually grouped with Layers and Paths window] in Photoshop. You will see four channels: RGB, Red channel, Green Channel and the Blue channel. Click on the Red, Blue and Green channels one after the other and see in which channel your model stands out the most from the background. Once you've found the right channel use the lasso tool [or the other suggested by the folks here] to isolate your element.

Using the channels lets you use tools like the magic wand more effectively, since the image is monochromatic.

Cheers!

Basically if you are saving a render from Cinema4D to Photoshop save it as a TIFF or TARGA with Alpha Channel. When you open it up in Photoshop just Ctrl+Click the Alpha Channel in the channels pane and you have your render. If you are rendering people though it all kind of matters what you will be using the image for. Like in my signature, I had to cut the woman out but I just did a very rough cut since I would be blending over it and brushing. The pen tool generally works best if you are looking for the smoothest render possible. There used to be an awesome site that I was a member of with forums called Render-World. Unfortunately it has shut down. On that note, a lot of good graphics sites have shut down. Artverve would have been awesome.

Here's what I meant.

First, supposing this is the model you want to isolate. This is a simple JPG render:


Then, when you render the scene from C4D [I use 3DS Max but the two apps are quite similar] as a PNG file [use this setting -- RGB 24 bit with alpha channel enabled] and open it in Photoshop, this is what your model will look like [inside Photoshop]:


As you can see, it's all primed and ready for use as a cut-out.

Easy, eh?

@Machine I think he meant cutting pictures he got from stock sites so he could put them in his creations.

The easiest way to render is using the pen tool on a new layer at about 40% transparency.

I'd suggest looking up some tools for it.

Oh! I thought he meant an image created by a 3D app, because he mentioned the word 'render'!

Haha, learn newb speak, XD

.....bite me.....

@ Magnus: I guess I'll have to

@ Drake: It's cool really, Drake , we were all newbies once [still are, in one area or another ]

i suppose.

seems pretty uncalled for when i ask for help, and assholes like him treat me like shit...

haha, oh wow. I didn't treat you like shit I gave you great advice

Guise, Guise, take it easy.

Any more flames and this thread will be locked.

The easiest way I've found is with the pen tool. It gets the best results for me. However, they ALL take time. A LOT of time. Also, you should learn to use them all, as there are times when one tool can do something more efficiently than others [This includes the eraser tool, as you can use it to help smooth out edges after cutting the image out.]

Another tip is, when after you finish cutting the image out, head to Layer >> Matting >> Defringe and use a setting of about 1-2 pixels.

After that, create a new layer behind the image and fill it with a dark color [Not necessarily black, but perhaps a dark gray.] This will allow you to see spots you may have missed before, which you can then clean up with the eraser tool.

Just have patience, and practice with easy images first [Things that don't have much of a background], you'll eventually become quicker at it. Just remember, the longer you spend on it, the better the final result, usually.

Absolutely.

i also find using Quick Mask Mode(press Q) is good for getting them really detailed bits of the render.
