x-Particles Wet Map Tag problem Tweet

[pcoombes]

Hi

I've run into a bit of a problem with the X-Particles Wet Map tag.

It's working and generating a Vertexmap, but I can't get it to render to the Picture Viewer and only to the Live Viewer if I hit the 'Send the scene' button.

In the texture I'm using for the floor, I'm using a Vertex Map node as the Amount input for a MixTexture node to generate a black and white map.

Is this a bug/limitation or is there something I'm not doing right?

Files attached.
Hit the Play button to see the effect.

Also, I get the same issue in R19.068 & Octane 2019.1.5-R3

Many thanks.

xpWetMap thing is not a supported object. You can use vertexmaps.

Thanks, aoktar,

The xpWetMap tag generates a vertex map, so as far as Octane knows it's just getting an animated vertex map in the Vertex Map node. Shouldn't that work?
Octane is just not updating that vertex map.

It doesn't recognize this type, just vertexmap/vertex color tags. Can't you convert xp tag to vertex map tag?

Yes, the xp Wet Map Tag outputs a vertex map - see the previously attached file.
You're saying use a Vertex Map and I'm saying I am using a Vertex Map.
The xp Wet Map Tag generates a Vertex Map and I'm using that Vertex Map in the material.

Octane doesn't update the Vertex Map unless I re-send the scene to the Live Viewer. And it doesn't work at all if I try and render it to the Picture Viewer.

I don't know how else to describe the problem!

I got it, don't worry! I read that very quick at morning, sorry!

For answer check the picture. There's not any dirty flags in vertexmap to detect the changes. As a workaround, use object tag with "force updates". Then it will update the mesh for every new frames.
The true solution is that the xpWetMap should trigger a flag in vertexmap.

Many thanks, aoktar, that works fine.
