I am also very frustrated. I am trying to view a simple html scene that I exported and am hosting on a website. In desktop view, I can see the options for stereo viewing, but in mobile, on the iPhone X (Safari browser), those options are not visible.

I would really appreciate if there was a step-by-step tutorial that shows the basics of setting up a 3D scene that can be viewed in a mobile VR viewer (in this case, I am using the Utopia 360, but it's essentially a plastic version of the Google Cardboard).
That would also include how to work with the iPhone's gyroscope. Thank you!!

I've noticed in the regular blender, there is an option to have particles spawn in either Jittered, Random or Grid ordering. If you have geometry with ordered vertices, they spawn particles in a linear fashion (with the Grid option).

However, I can't find that functionality in the blend4web interface. Particles seem to only spawn from random points along a mesh. Is it possible to recreate that grid option in the blend4web settings?

Thanks for the breakdown! This is incredibly helpful. I never thought to animate the UV channels themselves.

As for the problem downloading - it has since resolved itself. For some reason, I was unable to download the full blend file - it stopped at about 500kb. Anyways - all good!

Thank you Pavel. I'll give them a try!

EDIT: I'm having trouble downloading the blend file you attached for some reason. Can you share a screenshot of the relevant nodes? Thanks.

Ok. Perhaps I'm going about this the wrong way. What I'm trying to do is in essence animate a "X-Mas light" effect - a series of lights in a row lighting up in a sequence from left to right. How would I go about doing this?

Ahhhh. Thank you! No wonder I was confused. Basically I'm trying to simulate a light effect, passing from one LED to another along a curved lined of LEDs. I was animating the UV texture transform in Material Nodes, but clearly Blend4Web doesn't support Actions for that.

Is it possible to animate the vertices themselves in a UV map and have that play out in an Action?

Hi,

In the docs for blend4web, there's an image of blender's NLA editor showing keyframes for a shader Action. How on earth do I create this? It's been driving me crazy all day. I know how to create an action from IPO curves as long as its a simple transformation, but no luck when I want to animate a shader in the node tree.

Ah thanks Alexander. I posted just before I saw your reply! I'll give that a try.

I've made a simple flow chart thing to show what I intend. I have a suspicion the answer lies in either the "Switch Select" or the "Conditional Jump" nodes, but I don't understand how either of those work ;-)

Hi,

Just started getting into Blend4Web. Totally new to visual scripting, but a longtime Blender user.

How do I set up a node tree, so that blender checks what material an object currently has, and based on that, changes the object to the second material in the material slot?

I've attached an image that shows what I currently have. I can click on an object to change it's material but can't do anything else.

Thanks!
