New SG_AMBOCC Node

[gerardstrada]

The brilliant Sebastian Goetsch has released a nodal version of his excellent occlusion shader:

have fun!

Exellent! thanks for the tip.

Have tried directionnal mode for softshadows,
Select Light in Item Info output world position as target,
decrease angle (very low) math power the output for
darker shadow:

Ztreem, hope to see some of your cool experiments!

Denis, thanks for that tip! Other way to control the effect strength is with a gradient:



An example with a nice model from Aristomenis Stirbas:



The gradient can be useful to colored the effect as well:



Which looks like this:



If we want the effect interacting with shadows and other external shaders we can connect the node to Diffuse channel (Denis tip may be very useful here for adjusting the diffuse effect independently) and the gradient output color to Color channel:

The link comes back as unavailable for me.

The link didn't work the first 4 or 5 times for me, but it finally came through...Can't wait to try it out!

[LMUSIC]

Tried today and got it first time.

Was for updating the node (fix transparency problem).

A way to paint the occlusion effect is by using distance to object gradients:





I've exagerated the effect, but notice the radiance effect in this case is determined not only by gradient shape but also by the occlusion node, which gives us more realistic results.

A simple setup may be something like this:





We can get easily and very quickly a 'Pocoyo' style in this way





Though I'm sure the setup can be used for more realistic projects as well.

That looks fantastic! Any idea if a Mac version is coming?

[Wickster]

Very nice...I will be trying this out tonight. Thank you.

[Surrealist.]

What's this?

I lodded up the node plugin. I also have the layer plugin. Do they conflict?

[Sebastian G.]

Ram Sampath is working on the mac version.

Surrealist, this error message means that LW refused to provide the LWSCENEINFO_GLOBAL
Actually I have never seen this happening before, are you using a beta version?
If not please send me the scene and object file and I'll try to find out more
(skidbladnir at web.de )

Well it only happens in Modeler. I added the plugin in Layout and surfaced the object with the shader in the nodes edit mode.

Then in modeler it gives this message whenever I click on the surface or try and open the node editor. (not that I need to do that in modeler I was trying to change something else and noticed it happening.)

I downloaded the plugin from the site above at the top of the page.

It happens even on a simple object I put the surface on to test it. Maybe my plugin in is currupt. Check it out.

Ok, Modeler explains everything. I will take care of it in the next update.
