    Hi,

    I want to do an animation of an object animating with a curve path, however when I expert this to the verge, the animation doesnt hold its position. Is there a way to get this fixed. And selected item has a transparent material its not transperant in the Verge on browser any fix for that too?

    Hi there,

    Animation along a path/curve in Blender will not come over into Verge as an animation. You will need to bake the animation first.

    If you are using Blender 2.9.3 you can access this as follows:
    Object > Animation > Bake Action.

    Depending on your animation you may have to play with the various settings to get a good keyframe animation result but typically I use only: Visual Keying and Clear Parents and the results are as expected.

    You can then access these animations in verge using the animation puzzles.

    Transparent materials are a bit tricky in V3D. Its actually one of the first things I had to figure out. A simple solution is to open the Scooter demo provided by Soft8Soft in the Verge Application folder and append the glass into your scene. Using this as a starting point adjust the parameters as needed. There is also a Blender Essentials Materials Pack you can download that has transparent materials you can use as starting points. The trick is not all methods of creating transparent materials in Blender will work in V3D. You have to build transparent materials using shader nodes that are compatible with V3D.

    You need to bake it to keyfrane animation. To get this kind if defirming along the curve you need to add armature to the object, animate it along a curve and bake to keyfranes.

    Hi Zeon & Mikhail,

    Thank you so much for the response, much appreciated. I got the Transperant shader working from the Scooter sample file as suggested by Zeon and it worked perfectly, thanks a ton :yahoo: :yahoo: . However I tried to bake the animation to keyframe as suggested by you both with different options but its not working, i really need this for a demonstration can you please help me out. If you have a sample file can you pls share the blend file with me? :-(

    Happy to help. Because there are so many ways you could have created the animation and rigging of your objects it would be better if you could dumb down your scene to just the objects in question and share the file. Then I can give you step by step instructions and a return file with it baked.

    Hi Xeon,

    Thanks again for responding, attaching the blend file for your reference, i have not rigged anything, its just a simple Sphere crushed to look like fluid with a Curve modifier and moving it along a target curve. Please help me out.

    Yes, you do not rig anything, but you need to do this if you want to achieve something like you have in blender. It’s the only way.

    this is a good explanation of how to do it.
    Then once you have it done…then you can bake.
