come on!

Just to be sure...this is STILL not possible?!? Is this a joke????

Make this happen!

This is the exact reason why I'm no longer using SLOBS. C'mon now.

trapezoidal shape???? why is this still an issue? How are we supposed to create depth in virtual settings?

Free rotation not being present has just stopped me using this program. Asolute necessity!

@Shind0kai how do you control the circle? 

I have an image group on OBS that I have a mask on an image, the another image inside the group which then has another mask applied to the group - this give me a circle.

Looks like you can't add masks to groups, so I tried your way, but the circle is off centre and half of my image is masked out??

Pfft.  I can't even get the sources to resize on this nonsense for some "Scenes" anymore.  Thanks for taking something that worked and "fixing it" so it's a malfunction POS. 

Oh snap, nevermind, I totally read this thread incorrectly lol. Dyslexia is a bitch. Ignore my above post :D

Hey peeps, figured I'd post this here because I was also trying to figure this out.  Here's what I did:

1. Create a picture with your custom shape in it, make the background black and the foreground color of your shape, white.  (OR, for the purpose of this light tutorial, just download this awesome circle.png file that I stole/modified/re-uploaded: https://imgur.com/a/BOBbrHF 

2. Save it somewhere where you can find it easily.

3. In your cam source in SLOBS, right click on it > add filter > Image Mask/Blend.

4. In the 'Path' field, click 'Browse' > locate the circle.png file.

5. Done.

The default settings work fine, so I didn't have to adjust anything, but now this gives me a circular shape around my camera in my scene.  If you don't have Photoshop, just edit this circle.png in Paint or whatever free Paint app you have, and voila, a custom shaped cam for your viewers :)

Hope this helps!

I am having trouble changing the size of images uploaded. It seems the the mouse grab function isnt workings

Yeah, this makes SLOBS totally unusable. Especially since it randomly re-positioned every object in each scene when it imported from OBS.

Show stopper for me, really want to use steamlabs but don't want to lose the ability to truly create a custom layout the pure OBS give.

This feature would be really helpful, used it all the time on OBS.

BRO. 
TO CROP, HOLD ALT + DRAG THE EDGE OF THE SOURCE WINDOW.

I have a virtual set, where I have a monitor mounted on the wall which is slightly angled, therefore making it a trapezoidal shape.  I have a source behind the transparent monitor where I can show my Skype guest in the virtual set, however I cannot shape the source into a trapezoid to match the monitor shape.  Being able to reshape the source into non-90° angles increases the realism of the scene, Ana also ensures that 100% of the source is visible. As it stands now, everything outside of the trapezoid is missing.

i didnt use streamlabs OBS because the complete transform tool (bounding box etc.) are not available. It was important to put in short and long names in the same size of field ( example: a fixed line nearby "last follower" or something else)

Nevermind they just placed it somewhere else:

You have to add "Filters" which then allows you to crop,pad,stretch,etc.

^This needs to come back!
