Animate B4W_GLOW_OUTPUT?

12 October 2015 07:47
Hi there is there anyway to animate the B4W_GLOW_OUTPUT so that it's a pulsating glow?

Basically i want a area to glow so that the user's eye is attracted to a button.

I'm new to blend4web (but not Blender) so you may need to spell it out to me.

Thanks in advance.

Hi!
I made an example: our node TIME can help in this task. I wrote all the explanations in the file, so I hope it won't be difficult to understand :)

Oh, and of course you need node material for it

Wow that was a quick reply, thanks for that.

That's exactly what I was after.

One thing I did notice was on a mac though, was your notes weren't lining up in the Node Editor (see below)

Actually now I have another issue, here's what I'm trying to do



ie I have a "dotted line" object and a "glow line" object which pulsates.

but I want to hide the geometry of the "glow line" but still see the glow so that we can see the "dotted line" underneath it, is there anyway to do that, because when I make the "glow line" material's alpha = 0 it does nothing, and when I set it not to render in either the material rendering options or the object rendering properties it seems to cause errors (ie the whole scene becomes white when viewed in the SDK viewer except for shadows )

Oh, I see. Well, next time I'll make a screenshot

Did you choose transparency type? Because it must work with 0 alpha:

Hello and welcome to Blend4Web forums!
Please use blend files from this topic as examples. I think this will help you to learn this technique quite easily.
