xpTrail "color from particle" no working

[ak3d]

Hi.

I try to create the following:

- textured plane
- particles emitted from that plane, colors derived from the texture
- create trails in the same color as these particles

After many attempts I was able to get the particles color correct by using the "Instance color" shader. Unfortunatly I am not able to colorize the trails in the same way. I tried everything. These trails get their color from the particles but i am not able to render them properly with octane. I added the tag "render as hair" but I get no colors or wrong colors.

Please find a sample file attached.

Any help would be highly appreciated.

Thanks!

Hi,
here is a solution, by removing c4d shaders, and using a different projection in Planar/XYZ to UVW mode:
