Animation of PBR materials

Hi, I have made a nice rendering of my sailboat, I would like to make an animation of the waves in motion.
Can Bongo animate the Bump channel of a PBR material to make the water move ?
Can I load an .AVI etc of an animated bump map into the Bump channel ?
I can make the animated bump map in Adobe Aftereffects.


Yes, there is two ways you can achieve this effect. The first is to animate the offset of the bump texture to give it the impression of moving.

Waves

If you want to use a video or image sequence you can use the Bongo Video Texture

Hi Joshua,
Thank you for that, the offset method is pretty nice.
I will try making an animated bump map in AE and giving that a try.
Regards,
Mike.

Hi Again.
I have manged to get the water animated using a Bumpmap.AVI.
But… the viewport rendered animation in Bongo (top) looks totally different to the Cycles Rendered images in Bongo.(bottom)



Any Ideas ?

Can you paste your system info? I double checked with both a video, image sequence, and the offset method and Cycles seemed to render them alright. The video you’re using would also be useful so we can attempt to duplicate the issue here. @nathanletwory might also be able to help.

Quick guess would be to check texture mapping repeats.

Hi Guys,
I have attached the .3dm minus the boat model and my System info.

I’m not that much of a render specialist, but I think what you describe is normal. Allow me to clarify.
Below are 4 images.
The first 2 are the result of the 2 various Render engines that come along with Rhino 7: ‘Rhino Render’ (also referred to as RR7 or Cycles) and ‘Rhino Legacy Render’. The result of both differs slightly. A render engine creates an independent image to be used to your own content (e.g. assemble into a video).


RR7

Legacy render which exists for compatibility with Rhino 6.

Then there are 2 ‘Viewport display modes’ : Rendered and Raytraced . A display mode is a way of viewing the model in one of Rhino’s Viewport (see Rhinoceros Help)


Display mode Rendered

Display mode Raytraced

As far as I see and know the Raytraced display mode gives a pretty good (exact?) preview of what a final RR7/Cycles render will look like. But not the same goes for the Rendered display mode. In previous Rhino versions it was kind of a fast preview of a rendered image. Nowadays it’s merely still fast – fast enough to give a decent ‘rendered’ preview of an animation – but it does not give an adequate preview of a fully rendered image, no matter which engine is used. In particular texture and bump mapping but also shadows and reflections can be very different from an actual render.

That said, bump map on the ground plane should match quite closely.

I did make changes to the Raytraced / Rhino Render material handling code - maybe I made a mistake somewhere.

It does look like with a normal map Raytraced does the incorrect thing.

If I change to a different image the mappings match. Here I use the same image for base color and bump map:

I’ve logged this as RH-64943 Normal map on ground plane has incorrect mapping

Nathan,
Thanks in advance.
For one who doesn’t have a beast of a machine armed with a turbo GPU the ‘Rendered display mode’ is the only way to preview a rendered animation. So, for us animators, it would be very nice when the image comes close to the real thing.
Luc

Thanks guys,
I use a lot of software from different vendors, Autodesk, Trimble, Leica Geosystems, Faro etc
But their Tech support doesnt even come close to the support provided by McNeel.
Regards,
Mike.
