Emissive material like in Blocks leap motion demo?

Hi there.

I'm trying to reproduce the lighting effect in the cubes of the blocks demo, they of course are non-static objects, and they emmit light dynamically based on a texture, I have not being able to reproduce it (bear in mind I don't program shaders).

Here is what I am talking about:

Thanks in advance!

Cheers.

 

You'll want to use this asset: https://www.assetstore.unity3d.com/en/#!/content/17324

 

Yeah they might be using blooming, which is a simple algorithm to implement yourself. (it is in openGL maybe not unity).
but I doubt they actually emitt light I think its only color?

 

@acolgan.

Thanks!

But how did you do to "project" the object as emmited light? Because the bloom is cool, but what about the coasted light? I know it doesn't cast shadows, but it casts shapes, as for example with the icosahedrons the projected light shape is different than with the box or the rectangle.

@vikankraft
If you see the video, when you create an object there is some light shape being projected, and as I said just now, the shape is different with the box, rectangle and the icosahedron.
Any idea on how to get that projection effect?

Cheers!

 

It looks like a mix of bloom, SSR and point light cookies.

(an example of point light cookies)


(A further example with bloom and SSR for indirect lighting)

 

I though about point light cookies, but I'm not sure if I can use an spherically projected texture as cookie (which is what I think that could work for this).

What is SSR?

For the bloom they used the asset Acolgan said, and it's what I'm going to use.

Cheers.

 

Point light cookies use the same methods as cubemaps, i.e. spheremap, cylindrical, cubic, etc.

SSR is the most accurate way of calculating reflections and indirect lighting in realtime (you can kind of see it in the 2nd example of my previous post).

 

@Namey5

I haven't saw your examples, sorry, they are pretty cool, any guide or tutorial where I can learn how to take advantage of SSR?

Cheers and thanks for the info!

 

Something like this could work

 

Indeed!

This is pretty cool are you using any addons?

This goes for VR (like the blocks demo).

Cheers and thanks for the help!

 

No, this is just the standard shader, with a point light and attached cookie (made in photoshop w/ NVIDIA texture plugin). The bloom is included with unity and the SSR is compatible with the standard shader and is completely free on the asset store. Just note that it is still in development and requires deferred rendering.

Because it is a cookie, if the cube clips through objects the perspective will break somewhat, however you can use shadows.

 

Oh!

Cool!

But I'm having a problem, when I add, for example, the bloom effect to the camera (center eye anchor) all I get is a black screen in the unity game view and inside the Oculus Rift.

Any ideas on why is this happening and how can I use Image Effects with VR?

Cheers and thanks again! Namey5 you are helping me A LOT!!! REALLY REALLY THANKS!

 

I've not worked with VR myself, but after a bit of research, have you put the image effects on both left and right cameras? (not really sure how Oculus works in Unity, but that's the advice I've found on the matter).

 

well, in fact there is no left/right camera in Unity for VR, if I use the Rift prefab there is Left/Right anchor, but there is no camera, the only camera present, even during gameplay, is the center one, I'm not sure how it works, I'll ask in the VR forums.

Thanks anyway!!! You helped me A LOT.

 

Ok, I found the problem, in quality setting the antialiasing should be disabled, in any other case effects won't work

Thanks!
