Hi all,

I have a question regarding the colors of x-particles in octane. I'm using a plane with a texture as emitting source in x-particles. So all the particles that are emitting are getting the colors of this texture. I use an octane tag on the x-particles emitter, and a sphere as particle that i drag into the particle field in the octane tag. If I want these to render in octane, I use the instance color node on the diffuse channel and emission channel of my 'octane particle' material. In that instance-color node i select my emitter as a source. So far so good. the particles rendering fine with the color of the texture in octane.
What I want to do is making trails with a x-particle trail generator, so that these trails get the same color from each particle. So i put an octane tag on the trail generator and render them as hairs. Then i put the same material with the instance-color node on the trails. Now If I render, all hairs have the same color, and the instance color doesnt do anything. Am I doing something wrong here? Anyone has a solution for this?

See my scene file in attachment.

Thx in advance!

Unless something has changed recently, I don't think we can this still...

Did you checked sample scene for xp trails? It's under tutorials section.

I am having exactly the same issue with X-Particles. The trails have all the same color and they don't inherit the color from particle.
I had a look in sample scenes but there is only explained how to add random color.
Is there a way how to do it ?

Same problem. Anyone find anything new on this?

unfortunately its not possible for any 3rd party renderer to inherit the leading particle color for the trail due to the INSYDIUM API. Ive asked them about it a few times but was greeted with silence, since obviously they try to push Cycles. perhaps if more of us can be more vocal something will change eventually

Same problem.

The API now has access to these attributes. Not tried it in Octane, but have been successful in another renderer, so I'm sure Otoy must have implemented the link too.

I don't know ANY API as you said. And it's not an Otoy job. Plugin is 3rd party development.

Hi @aoktar

Insydium became friendly with trail colouring as of X-Particles V4 build 690 (Early Access).
